i need to buy a mask and snorkel for my class and wanted to look at some diff. ones before i just bought from my local dive shop. is there any recommended brand? i am going to have it for a while so i want it to be good. thanks!
 
The most important thing is fit, try on a whole bunch and then make your decision. I got a dry snorkle and really like it, but I mostly use it for snorkeling, I use a fold up snorkle in my BCD pocket for diving if needed.
 
Choosing a mask is a highly personalized decision... I think you'll find as many differing opinions on them as you will offerings in the marketplace.

There's a recommended thread located here: http://reefcentral.com/forums/showthread.php?s=&threadid=1660155 In it, we talk about recommended places to purchase gear online, as well as some advice on purchasing a new mask.

Snorkels - they're great for snorkeling. Most divers never use it again after they get their Open Water certification (required), unless they actually go SNORKELING... And frankly, the only time that makes sense is when you're in clear water (can see the bottom from the surface) and for whatever reason, aren't scuba diving (like you're out of air and can't).

There are some that really enjoy the freedom of diving without tanks - they call it "freediving" - which usually involves heavy physical training and the art of learning to hold your breath for many minutes at a time. It's the same as "snorkeling," although that term is usually reserved for recreational, vacation-style stuff without the extreme physical conditioning of freediving.

At any rate, unless you plan on learning the art and challenge of freediving (in which case you'll end up spending comparatively big bucks on the perfect freediving snorkel - if you choose to dive with one at all), then I would avoid the purchase of a snorkel altogether and borrow one. If you can't, then buy cheap and simple... In most cases, the snorkel ends up in your attic in a matter of a month or two.

i didn't see anything in there that discusses where i should get my mask and stuff. i think i found this website from looking on RC that i really liked but now i can't find it. that was last week.
 
Well, masks are so personal - and need to be tried on - so I would hit as many dive shops as is practical and try them all. I would recommend black skirts over clear, and I would recommend as few individual pieces of glass as possible - single window is great, although personally I find a better fit out of a two-window mask than out of a single-window mask or "frameless" mask. I do use a frameless as a backup mask, however, since they stow so flat.

I would avoid clear-skirted masks for the reason I mention in the other thread, which I gave a link to in my previous post. I would also avoid four, six, and more window masks. These things look like a really great idea in the dive shop, but once underwater, they tend to refract light just like an aquarium does... So the more individual pieces of glass you have, the more likely you are to see the same image in each window, which is odd and confusing... To say nothing about the high volume that multiple-window masks create and the issues associated with that.

Anyway... Locations... Honestly, it's not nearly as important as trying the mask on. With today's soft silicones, you can pretty much get any mask to fit, but some will simply fit better than others. Some of my favorites include the Halcyon "low volume" two-window mask, Halcyon's frameless mask, any Scubapro mask, any Atomic mask, and any Dive Rite mask. I also see a lot of people who like the black-skirted Cressi mask, which seems to fit small faces really well.

Once you find the mask that fits you exactly right, buy it right there in the shop that you found it. Alternatively, http://www.Scuba.com is good, http://www.Leisurepro.com is fantastic (highly recommended) and http://www.Extreme-Exposure.com is tops - although pricey (worth it). http://www.DiversDirect.com is very good as well... And I love the guys at http://www.ScubaToys.com. Also, http://www.Austins.com in Miami will sell ScubaPro over the phone, even though ScubaPro frowns on the practice. So if you find the right mask and feel that the shop is jerking you around, then you can always find pretty much anything you want at one of those online shops.

have to agree with seajay. you have to try on a bunch of masks to find the right fit. I also keep a frameless as a back-up that tucks away easily in my pocket. As far as a snorkel...personally i think the cheapest snorkel you can find is the best! after you finish open water class you will almost never use a snorkel. My motto is... if you are using a snorkel when you intended to be scuba diving, that means you really messed up BIG. After a dive you should still have more than enough gas to just chill on the surface. Being you paid for that gas in the tank you should breathe the stuff you paid for while on the surface after a dive So a snorkel is almost worthless so it makes no sense to pay a lot of money for something you shouldnt really need to use.
 
By the way, if you happen to have a mustache, just shave it off because it leaks like crazy around the seal. My hubby tried shaving it just from the top (looked like a blonde hitler) then he just shaved the whole thing and the mask fit great.
 
Buy from your local dive shop --- you might spend another $10 on your mask, but you'll get a personalized fit, better customer service when it breaks and will support the local market.

Also be aware that Leisure Pro is grey market for alot of the gear they sell, which is why they sell below MAP and MSRP-- its not a MFG warranty on the products.
 
I agree with kmitch - there's value in buying from your local dive shop... If you can go in there and get personalized customer service and try something on and see it before buying it, then it's worth spending more. The LDS is also a place where you can get your tanks serviced and filled, rent gear that you need, receive training for the dives that you want to do, and find deals on dive trips. The LDS also tends to be the local hub for diving information such as, "Where's the coolest spot to dive," and "Has anyone ever found 'X' shipwreck."

...So it's beneficial for everyone to support their local dive shop.

That said, remember that in almost all cases, the online dive shops are ALSO often an LDS. In Leisurepro's case, for example (by far the largest online source of dive gear), they are a local dive shop in New York City. Buying from them IS buying from an LDS... Just as it is in many cases when you buy online.

...And frankly, I have, in every case I've ever experienced, received BETTER customer service from them than from my local dive shops in Savannah or Charleston, which are my geographically closest dive shops.

...Which shouldn't be a surprise - certainly the level of customer service and professionalism can be expected to be higher from a shop that is competing in the global market versus one that is only competing on the local level.

Pricing is interesting, too... In most cases, I have not found there to be a $10 difference between my LDS and online sources like Leisurepro... I have found there to be a $200 difference... Or $100 differerence. In many cases, percentage-wise, the difference in price exceeds 50% - AND I get better customer service, a more knowlegable staff, the goods delievered right to my door, and... Yes, often a BETTER warranty.

It's true that much of the inventory that some of these places sells doesn't come directly from the manufacturer through the traditional "manufacturer's reps." In some cases, it's purchased overseas, where a monetary exchange rate is so good that it brings the price of the item down. In many other cases, Leisurepro has acquired inventory from other LDSes going out of business. Regardless, all inventory DID come from the manufacturer, which is to say that by law, it is still under warranty regardless of how it got into the consumer's hands.

For those items that do NOT have a warranty (for example, if a manufacturer illegally claims that since it was purchased online, it is NOT under warranty), Leisurepro adds their own warranty at no additional cost... Which far exceeds what the manufacturer gives on the item anyway. I have had personal experience with just this sort of thing, and I can tell you that I was blown away by the level of warranty and service that I received from Leisurepro.

"Grey market?" Not exactly... More like, "Found the right supply chain," that's all... And with more and more consumers making purchases online, it's financially stupid for any LDS to ignore it, not participate in it, chastize it, and then complain about it. The bottom line in the U.S. is that it is the CONSUMER that dictates a paradigm shift, not the manufacturer and the "manufacturer's reps." That's how a free economy works, and those in the industry who provide the consumer with a better way or a less expensive way of purchasing are going to find themselves with a competitive advantage.

...And another LDS will go out of business while they complain that internet sales are killing them.

...And Leisurepro will come in, last minute, buy out their inventory, and sell it to their clients for less, knowlegably, and directly to their door... With a smile and a better warranty.

Do not believe the LDS that doesn't understand the paradigm shift. Being in business is "all about" understanding the marketplace, it's driving forces, and how to maximize profitability by predicting them.

When you buy out the products from a shop going out of business and then sell them for less then MSRP and MAP because you aren't an authorized dealer for your product and they therefor don't have the warranty, then it is grey market and you are killing the LDS.

That being said, I work for a store that has a large internet presence amongst technical divers.... I understand that dynamic of online retailers. But as someone who sells online, I am telling you that you will get better service at a good dive shop than online! If nothing else, buy your basic stuff off the internet but go to your dive shop for regulators, BCs, and other life support. Remember your life is worth the extra money you might pay, and that a good relationship with your dive shop will keep you diving and keep you happy!

Safe and Happy Diving

Negative. That's just the sort of flimflam that LDSes propagate in order to justify their losses.

Look... If they aren't an authorized dealer, then they can sell whatever they want for whatever the market will bear. Such is the law, which supports a free market. Welcome to the world of capitalism.

In fact, AUTHORIZED DEALERS are able to do the same... It's just that the "factory" can then "pull" their "factory authorized" status. So what? Find another source for your inventory. Leisurepro did, and it seems to be working pretty well.

It also sends a BIG message to the "factory reps," which are NOT employed by the "factory" - that they're asking too much for the product, and it's time to rethink their supply chain.

Here's what a "factory rep" is: A "factory rep" is a company that comes in, buys 100 "dive widgets" and resells them to the LDS. If the LDS finds another supply chain other than them, then they threaten all kinds of stuff - including the "loss" of "factory authorized" status. So what? It hasn't bothered any of the internet sellers... In fact, it's working out quite nicely for them.

Look, if the whole thing really bothers you, then why don't YOU buy out the shop going out of business, then? Then you can sell whatever you want, whenever you want, and at whatever price you want... With whatever warranty you want. If you're really an employee at an LDS, then you'll realize that this isn't any different from what you've got with the "factory reps" - except that YOU are able to decide how to handle pricing, packaging, warranty, and everything else.

...Just like "the internet" does.


That being said, I work for a store that has a large internet presence amongst technical divers.... I understand that dynamic of online retailers. But as someone who sells online, I am telling you that you will get better service at a good dive shop than online!

Really? So I wouldn't get better service buying a new backplate from you than a "recreational" shop in Charleston?

Given that they've never even HEARD of a backplate in that particular shop, I'm pretty sure that I'd get better service from you if you know them, sell them, and understand them... Which, if you're a "technical" shop, I'm sure you do.

...But if you believe the rhetoric that you're spouting above, I'm "killing" my LDS if I buy from you because you're not geographically close to me. Silly, isn't it?

...And when it comes to life support equipment, especially of the "technical" kind, doesn't it make more sense to prioritize customer service and product knowledge over geographical region? I can tell you that when it comes to serious gear, I don't give a rat's patoot where I get it - just that it works as advertised and that I have the knowledge and understanding to use it properly.


If nothing else, buy your basic stuff off the internet but go to your dive shop for regulators, BCs, and other life support.

It's ALL "life support." I can assure you that a failed mask or a failed fin or a failed suit is definitely life-threatening in ANY "tech" situation. Imagine trying to exit 2 miles out of a cave with a broken fin... On time, so you've got enough gas to do it. Imagine popping out a mask lens at 200' on a wreck dive. You don't think that would be life threatening? What about a flooded drysuit in 60* water with two hours of deco obligation requiring you to stay wet? Exactly which part of your gear is "basic" and NOT "life support?"

You claim to be a "tech" shop, but your attitude tells me to be very afraid. :)

You say that your shop has a "large online presence." So are you in support of online purchasing or not? This baloney you're spouting about "killing the LDS" is totally hypocritical if you're doing business online... Which side of the fence that you've erected are you on?
 
haha, I think you're reading between the lines too closely.

If you've never worked at a dive shop and seen the equipment that people have brought in from leisure pro, then don't tell me its kosher. I've seen LP take a octo, change the faceplate on it from yellow to black and turn it into a second stage on a primary regulator. Customer took it diving and it started to free flow. Why? That particular model and brand has more differences between the primary second stage and the octo second stage than just a faceplate, and when parts kits designed and intended for the primary were installed into what was really an octo that LP sold as a primary, it nearly killed the diver. Tell the diver who nearly died because they tried to save a buck at leisure pro that they are legit.

Our online shop has a brick and mortar retail location. You will absolutely get better service from me by coming into the shop than you will if you buy online... example being that backplate/harness. You buy it online and I won't be able to help you fit it personally and give you the correct setup and placement for those d-rings like I can if you are physically standing in front of me. Sure in a location where no technical dive shops can be found, you will be better suited to go to the internet and 'do it yourself' but if we're talking a recreational diver, like the OP is, then he'll get better treatment in a dive shop than online. I am saying that as an instructor, as a person standing behind the counter, and as someone who sells online.

Sure it is all 'life support' and I'd rather sell you the whole thing online because I'll make another buck. But going back to what I said earlier, the OP is a recreational diver, the chances of him having a 200' mask issue (in which case *** is he doing at 200ft?) are pretty slim. As a fellow diver, I understand it is an expensive hobby, especially when you initially get into it. If the difference between you diving and not diving is being able to afford your gear, and that means that you need to buy some of it online to do so, then buy that stuff online. But when your regulator breaks, its nice to have someone physically standing there to shake a stick at.

Sure I want you to buy online from my dive shop, I'll feed my family better if you do. But I also know that I can't give you the same service online as I can instore, so really I'd prefer you physically come in. Technical diving and recreational diving as they play out on the internet are two different things too... places like Leisure Pro don't sell enough tech gear to really make a mark, and the serious tech divers know better than to buy gear from the shop that 'has no idea what a backplate is'. If they live in west bumtown, they'll buy it online because thats the only place they can get that gear, and they'll buy it from a technical only online retailer so they know the place that is sending that backplate knows what it is.

Safe diving!

I'm sorry... Should I be reading your posts less closely?

LOL... Actually it IS kosher... Leisurepro is Jewish-owned. :)

What makes you think I have never worked in a dive shop?


I've seen LP take a octo, change the faceplate on it from yellow to black and turn it into a second stage on a primary regulator. Customer took it diving and it started to free flow. Why? That particular model and brand has more differences between the primary second stage and the octo second stage than just a faceplate, and when parts kits designed and intended for the primary were installed into what was really an octo that LP sold as a primary, it nearly killed the diver.

Really? Exactly what brand and model was this?

...And how did this "nearly kill the diver?" And what does the color of the faceplate have to do with diving with an unsafe second stage?

Think about this for a moment... If the backup second stage is not able to be used as a primary second stage, then what's it's point?

...And why would you give that to a diver that needed gas? I would think that if your buddy was suddenly out of air, you'd want to give him a good-performing, safe regulator... Not some piece of junk that breathes like crap or freeflows easily. Certainly that would make a really bad situation worse!

...Any "technical" diver knows this - and so they never consider the "backup" second stage to be okay to perform any less than than their "primary" second stage.

...Which is why I have doubts about you being a "technical" diver in a "technical" dive shop. Real "technical" dive shops don't call themselves "technical," don't differentiate between second stages as "primary" or "backup" based on performance, don't use the word, "octo," and certainly do not care what color the faceplate is. What's the name of your shop? Where are you located?

...And here's the harm in identifying yourself as someone who works in a "technical" dive shop if you really don't... Others might believe you - and you are definitely not pointing people in a safe direction when it comes to life support equipment.


Tell the diver who nearly died because they tried to save a buck at leisure pro that they are legit.


They are very "legit," and I have purchased many things from them. I've always gotten the best of service from them. I also suspect that they do more business in one day than "your technical shop" does in a year.

If someone you know "nearly died" because of a free-flowing regulator (I'm beginning to suspect a lot of things you're spouting here), then I would question the diver himself... Why was this diver unable to cope with a freeflow? Where was his buddy? And why did this diver dive on a second stage that freeflowed so easily? Did he not know it when he got in the water? Did he not know it at 10' of depth? 20'? Can this diver not do an ESA from 10'?

If you have a difficult time understanding how a problem like you describe is actually the diver's fault, then at least blame the last person to service the regulator. If it had never been serviced, then it's the manufacturer's fault. Blaming the issue on the shop where the regulator was purchased is completely ludicrous.


Sure I want you to buy online from my dive shop, I'll feed my family better if you do.

I see... So you don't have an issue with "buying online," you have an issue with Leisurepro. Buying online is okay just so long as it's at your shop.


But I also know that I can't give you the same service online as I can instore, so really I'd prefer you physically come in.

I think what you're implying is that if someone comes in to your store (vs. buying from you online), you can give them more personalized attention, and help them purchase what you think is best for them, based on your experience and expertise.

Look - I don't mean this offensively, but if you're going to propagate to your clients some of the things you've said here, then I would stay far away from your store. See, that's one of the advantages I find to purchasing online... No salespeople to argue with who "think" they're "helping." Simply sell me what I want, thank you.


Technical diving and recreational diving as they play out on the internet are two different things too... places like Leisure Pro don't sell enough tech gear to really make a mark, and the serious tech divers know better than to buy gear from the shop that 'has no idea what a backplate is'.

Ummmm... *I* buy a lot of stuff from Leisurepro. So do many of my "technical" buddies.

I don't know where you're getting your ideas about Leisurepro, but yes, most of the people there know exactly what a backplate is. In fact, many of the employees there dive backplates. That's why they're a popular item for sale there: http://www.leisurepro.com/Catalog.aspx?op=dtSearch&Term=backplate

Who told you they don't sell backplates?


If they live in west bumtown, they'll buy it online because thats the only place they can get that gear, and they'll buy it from a technical only online retailer so they know the place that is sending that backplate knows what it is.

Where did you get this stuff? And exactly what makes a retailer "technical only?"

SeaJay,

Not worth arguing and wasting more time with you, I wish you the best of luck with your tech dive gear from leisure pro.

BTW - the incident with the divers octo from leisure pro happened while I worked at a shop in atlanta that caters to recreational divers. recreational diving- handing off an octo rather than donating from your mouth on a long hose is the norm. That was several years ago, I now work for another shop that caters to technical divers, so yes, you are correct, I'd advocate for donating out of mouth now rather than octo. Faceplate color on the octo has nothing to do with it, the parts and o-rings designed for the alternate were not the same parts kits for the primary, so when LP repackaged what was built as an alternate and required those parts as a primary, they nearly killed someone.

I'm glad you enjoy shopping at leisure pro, I wish you the best of luck and safe and happy diving in the future.

PS - its because of nonsense debates like this that I stay off scubaboard and the like... since leisure pro doesn't sell anything for my rebreather its a non issue :D

If anyone could consider this a waste of time, it would be me... I'm the guy that owns a commercial dive operation, and as long as I'm sitting here pointing out the obvious technical flaws in your diatribe, I'm not under water, making money. Still, I care about this community and I fear that if left unchecked, your influence could lead some to dive unsafely.

For that reason, despite the fact that I could consider this a "waste of time," I don't.

I don't see why you would consider it a waste of time... You're the one that started this stuff and made claims of being in the "technical" dive industry.


I wish you the best of luck with your tech dive gear from leisure pro.

Thank you.

I don't buy "technical dive gear" from LeisurePro... I buy dive gear from Leisurepro... As well as many other places, just like I mentioned above. Even the most "technical" of dive shops don't call themselves "technical." To do so would be business suicide - no diver starts "technical," and rarely does a diver actively persue "technical" diving... They simply dive a lot, and find themselves pushing "recreational" dive limits. "Technical" divers are a minority group within the minority group of scuba divers in the first place... To create a shop that caters exclusively to divers of a "technical" sort would be rediculous. The market simply wouldn't bear it, and without the income created by new divers looking for their first certification and their first bit of dive gear, the shop would quickly crumble.

...Which is why no shop ever refers to itself as "technical." By definition, that is "beyond recreational dive limits," and legally and liability-wise, stupid... As well as financially stupid. Dive shops that cater to divers that dive beyond recreational dive limits would never call themselves "technical" - only the shops that identify themselves as "recreational" consider other dive shops "technical." It's simply a loser's excuse for why they carry crappy gear and lose their divers to the shop down the street as soon as they get certified. The reality is that there is no definitive difference between "technical" and "rereational" diving... And as a whole, people in the dive industry know that.


BTW - the incident with the divers octo from leisure pro happened while I worked at a shop in atlanta.

Really? What shop? What was the diver's name? What brand of gear was he using, and what model was he using?


...the parts and o-rings designed for the alternate were not the same parts kits for the primary

Really? What brand and model?

I would be surprised to see such a thing exist in the dive industry... Every manufacturer's parts kit that I've ever purchased is the same for all of their regulators. The reason is simple... If all of their second stages use the same parts kit, there's less confusion, less inventory, and the dive shop tech won't inadvertently receive the incorrect parts kit and attempt to install it on the incorrect regulator.

...But then again, I very rarely see a "parts kit" purchased by a shop anyway - typically, a well-stocked shop will simply have a healthy supply of all of the o-rings and lube and parts that it needs so that they don't have to purchase a "parts kit" for each regulator. This also allows them to use higher-quality o-rings and lubricants than what typically come supplied in the manufacturer's "parts kit."


...so when LP repackaged what was built as an alternate and required those parts as a primary, they nearly killed someone.

That's the third or fourth time you've said that - I sure wish you'd back it up if you're going to make that claim. What was the diver's name? What brand/model regulator? What "additional parts" did Leisurepro not put on an "octo" to make it worthy as a primary second stage? How did this create a freeflow? And why was a freeflow life-threatening for the diver?


...since leisure pro doesn't sell anything for my rebreather its a non issue :D

What kind of rebreather do you own?

Rebreathers don't replace open circuit gear. A diver using a rebreather will still need stage bottles (or "bailout bottles") with regulators, hoses and gauges. He'll also still need wetsuits, drysuits, fins, masks, lift bags, spools, reels, lights, gear bags, Pelican cases, wings, webbing, line, and yes, even tank fills. It's just that now, he'll also have a need for Sodasorb, various rebreather maintenance items, and in some cases, batteries for his rebreather. What makes you think that having a rebreather somehow negates a diver's need to find a source for dive gear? Don't even get me started if the diver's on a scooter... Or spearfishes... Or is into photography or videography... Or owns a boat to dive from. :)

I would think that if you were really diving with a rebreather, you'd love Leisurepro.

I didn't see you take the obvious opportunity to mention your "technical" dive shop's name. I personally don't know of a "technical" dive shop in or around the D.C. area... Do you sell helium? Argon? Do you have a Haskel booster?

I'm doing an interesting dive with a max depth of 285 ft in about two months off of North Carolina on an unknown shipwreck. What would you recommend as a back gas? Alternatively, what brand of rebreather would you recommend, and what END would you recommend while I'm on the bottom?

Ya gotta stop using the word "tech," kmitch... It makes you look like a stroke. :) A "tech" is the guy that services the regs, man... Not a description of the dive.

Divers Supply, Marietta, GA. It was Sherwood, don't remember the model, it's been about 5 yrs since this happened. Just memorable incident. Customer's name isn't internet appropriate material. It took us days of installing and testing and calling Sherwood before the serial numbers on the 2nd stage were matched to an octo rather than primary. Struck us as very bizarre as well. We'd been putting in another parts kit, but when we put in the parts designed for the octo rather than primary, viola, problem solved. Doesn't make sense either, they should copy and paste and just change faceplate color for efficiency when making parts kits.... who knows what they were thinking.

When they came back in after we got the correct parts in there, we asked where they purchased it (we are an authorized dealer for the brand, but didn't happen to sell this one to the customer in question). Responded with Leisure Pro. Follow up with Sherwood after the fact revealed what happened.

Again, the model exactly and customer name have passed to history, I see thousands of regs a year, and while I think I've got a good memory for customer names, it's not that good! ;)

What kind of rebreather do you own?
Dive Rite O2ptima FX. I didn't say anything about rebreathers replacing OC gear? But Leisure Pro doesn't sell much that applies to my rebreather that I don't already have from diving OC, unless of course they started a new business plan that I haven't seen yet... And when my rebreather breaks, its nice to have an authorized dealer to take it back to. I don't mind paying extra for service. Do you need my handset serial numbers to verify that I own one?

Reef Central isn't designed for me to poach business for my dive shop. I'll mention the name of shops I've previously worked for since I'd no longer be advertising on their behalf, but as a current employee, there is no place for me to advertise their name here. Yes we fill Helium, Argon, Bank 30%, and have a Haskel Mini and Regular booster (for when we take the CCRs to honduras)... there are 4 CCRs on the showroom of the floor right now, at least 5 sets of doubles on the fill station since we're going to canada to do some trimix dives there later this month.

My dives off NC typically are 130ft or shallower, so I'd use 30% as a back gas or bailout on the unit. If you're going to add helium into it then I'd need to pull out my tables which aren't here at work to figure out what the equiv narcosis depth of given gases would be to determine what would be best at 285. I personally don't get off on going deep, I'd rather stay 200ft or shallower and stay for a long darn time (like the week in Cozumel I just came back from, 160ft for an hour with hardly any deco). I prefer eCCRs to mCCRs, I choose the O2ptima because I don't like packing scrubbers and like that the parts are easily available in the US, unlike units like the Inspo or Evo where you have to go to the UK for parts. But on the other hand I love the vision electronics package that AP diving puts on their units. Not a fan of Megs due to their weight and I fly with my unit regularly.

happy diving

It took us days of installing and testing and calling Sherwood before the serial numbers on the 2nd stage were matched to an octo rather than primary. Struck us as very bizarre as well.


Doesn't make sense either, they should copy and paste and just change faceplate color for efficiency when making parts kits.... who knows what they were thinking.

...Then I guess you understand why I've been so suspicious. The story is pretty incredible.


Do you need my handset serial numbers to verify that I own one?

Heh... No. :) Forgive me for drilling you so hard - I'm sure you understand, what with all of the stuff that slings around out here on the 'net. :)

Odd... In this last post, you sound like a completely different person. I stand corrected, then. :)


My dives off NC typically are 130ft or shallower, so I'd use 30% as a back gas or bailout on the unit. If you're going to add helium into it then I'd need to pull out my tables which aren't here at work to figure out what the equiv narcosis depth of given gases would be to determine what would be best at 285.

Unusual that the shop would bank 30%... It's somewhat of a non-standard mix, unless you guys are doing the "rec triox" and 30/30 mixing thing. Even then, physiologically 30/30 simply looks like EAN32, which is a standard mix. I've never seen anyone bank anything but air (common) or 32% (unusual, but big for shops that encourage EANx or "nitrox"). Do they really have such a demand for 30% that they choose that to bank?

BTW, you shouldn't have to "figure out what mix would be best at 285." Simply use standard gasses. See, if things are standardized, you get to know it all really well and it becomes second nature so you don't have to constantly do calculations for 5 or 10 or even 20 feet. It's just not such an exact science that you need to dial in "the right mix.' I'll probably spend most of the dive just off the bottom anyway, around 260' - less if I'm on the deck. Standard gasses will put my END between 80' and 100', regardless of where I am in the water column, because I'll switch if I go out of that range.

...Such is the luxury of using standard gasses.


I personally don't get off on going deep, I'd rather stay 200ft or shallower and stay for a long darn time (like the week in Cozumel I just came back from, 160ft for an hour with hardly any deco).

I guess it depends on what you're used to.

BTW, you can stay as long as you like at any depth you like... Any other teaching is false and propagated by self-professed "recreational" agencies in order to abbreviate their initial classes and smooth the learning curve (read: "pass more people"). You've simply got to spend the time in decompression (which you do anyway, even when diving withing "recreational" dive limits), and be breathing the right gas at the right depth (END within limits and PPO2 within limits). From there, it's simply a matter of having enough gas to make your stops.

...Which is the beauty of a rebreather. You've got a lot more gas with you if you're on one than with open circuit - since much of what you breathe out is recycled. That's it. Using a rebreather is simply a benefit because you don't have to take as many bottles with you, that's all.

What was your profile like on your 160' dive? What was this "short" deco, and why was it abbreviated? Did you mix heliox or something?

Yeah, I honestly don't seek deep stuff either - there's a lot of logistics that go into play when depth goes below 250' or so, and a lot of gear won't handle the pressure... I'm thinking housings, scooters, and the like.

Unfortunately, that's where my job is. It means a 3-day boat trip, lots of cold, dark water, and little possibility of getting help fast if the fit hits the shan. However, the payoff... :)

Understood, and I figured out thats what you were looking for... theres alot of people who talk to talk but don't walk the walk. I don't spend time on dive forums for that reason, too many couch divers.


...Then I guess you understand why I've been so suspicious. The story is pretty incredible.

Which is why I remember it so vividly. I've never seen so many equipment techs unable to stop a seeping 2nd stage. When you consider different sized o-rings, it makes sense. Sherwood recently did a major line overhaul of their regs to move things like the brute out of their line and put the SR1 as their front runner. I can visualize the reg's second stage, but don't remember its name for the life of me. It's chewing on me now.... haha

Yep. We seasonally go between 32% and 30% banked. Most N. Carolina divers use 30% because the MOD is for 1.4 in the 130ft range, and the recreational wrecks are all in the 110-120ft range. Olympus Dive Center (who I also used to work for, I still make their website) banks 30% and that is their 'bread and butter' fill. Since NC is so close for us, alot of customers do weekend trips down there. 30% is a great mix to cover anything above 130ft.

What was your profile like? What was this "short" deco, and why was it abbreviated? Did you mix heliox or something?

Short deco only in the sense that it was on the CCR. After 50mins my time to surface (mind you I wasn't constantly at 160, some up and down taking pics) was 15 mins, first deep stop at 70fsw. Most of the stops I worked off before I even got there. Other thing is that on the rebreather when I get shallow for my 30ft stops I pump up my PO2 fairly high and off gas faster. In the end I had a slow ascent with a 5 min "safety stop". Gas varied, air part of the week, trimix the other half. I don't remember the mix off the top of my head, we just kept topping off what we'd used that day so it wasn't a clean 15/35 mix or something. I got the rebreather for taking pics (its paid off) and after 200ft the logistics of picture taking changes enough to not warrant it for me, plus the overhead hassles. I can sling a 40cft bailout on my rebreather down to 200, but past there I really need a high o2 mix and a low o2 bailout, and probably have to move into al80s. Being as I'm 5'6" and 120lbs (woman), thats alot of crud to haul just for a few extra feet.

PS-what do you mean by 'standard gasses'? Obviously you aren't using air at 285 (PO2 is 1.4 at 220), so you must be talking about like a 15/35 type mix? Since I don't dive that deep regularly I'd still have to pull out the tables to find out END on them - too much stuff in my head to commit something like that to memory! I guess for commercial diving it's applicable.

Beaufort, SC..... must dive Jocasse a bunch?

Sometimes. :) I've spent more time in Lake Murray, though. A couple of years ago I assisted with a job of raising a B-25 out of the lake. That was pretty cool. :)

...Did a little work, too, with the Hunley submarine in Charleston. Of course, that was just offshore.

...Right now, I've been working all week for Embarq, doing some line work both at depth and on top of towers... Fiber problems. I'm also working on a couple of big projects - one off of Savannah, GA, looking for a lost nuclear bomb (http://www.lost-h-bomb.com if you want to see the TV show about it - I'm the diver heading the team... And not wearing gloves) and one off of North Carolina (platinum recovery). There's another project a few hundred miles off of Venezuela that will be next, but I plan to use funding from the NC dives to cover expenses for that recovery. Frankly, it's needed - deep dives hundreds of miles off of Venezuela are really, really expensive. :)

Honestly, I get bored any more just going diving for the sake of diving. I mean, I still love it, but what really turns me on is diving with a purpose... So I basically go where the excitement is, and base my training on need rather than going and doing dives that fulfill what I've been trained for thus far. It's kind of an opposite way of diving than what most agencies encourage.

I think you mean that the PPO2 is 1.4 in the 130 ft range... But I get your drift. :)


and the recreational wrecks are all in the 110-120ft range. Olympus Dive Center (who I also used to work for, I still make their website) banks 30% and that is their 'bread and butter' fill.

Strange. A localized phenomenon. :)

Hm. Didn't it worry you to not know exactly what you were breathing?


I can sling a 40cft bailout on my rebreather down to 200, but past there I really need a high o2 mix and a low o2 bailout, and probably have to move into al80s. Being as I'm 5'6" and 120lbs (woman), thats alot of crud to haul just for a few extra feet.

Yep - very bulky. The rebreather was probably a really good idea.

That said, you do realize that no matter whether it's a single AL40 or four AL80's, they still weigh nothing in the water, right? Okay, they're a couple of pounds negative full and a couple of pounds positive empty, but effectively, they weigh nothing. I've seen girls smaller than you handle a lot more.

Too cool to find a female "technical" diver - I can count on one hand how many I know. Nice to see it in such a male-dominated "sport."

Standard bottom gasses are:

10-100 32% or 30/30 (O2/He)
110-150 21/35 (O2/He)
160-200 18/45 (O2/He)
210-250 15/55 (O2/He)
260-400 10/70 (O2/He)

Decompression mixes would be:

20 100% Oxygen
70 50% Oxygen
120 35/25 (O2/He)
190 21/35 (O2/He)

For the dive to 285', I'd have 10/70 as a backgas.
