But it can quickly become a PIA at 85' with a very strong current trying to blow you into a wreck... Don't ask me how I know this! :bigeyes:

It wasn't an issue at all because I simply cut the depth in half to alleviate any concerns over drifting into the coral encrusted wreck, then enjoyed the hell out of the top-down view of the remainder of the dive site. 
What happened was my bungee cord snapped on my computer, so it was flying all about... Being a "commercial aquaculturist", I was far more concerned with ecological damage than anything else, so I popped to a safe distance while numerous other divers grabbed onto this and that while being blown into the wreck.
That's one of the reasons that I now have a re-newed way of thinking about the clutter issue and the entire DIR approach. Doing my first cavern/limited cave dive 2 days after the wreck situation above, I had my gear somewhat overhauled by the guys that know more than any of us could ever begin to hope to know (SeaJay's mentors!) and it made a world of difference in regards to potentially alleviating snags in a very confined environment.
I'm just a n00b though.
BTW: While I do have a couple of 100+ foot dives in at this point, I can't wait for the opportunity to go below 200' with SeaJay someday :bounce3: <-- No, it won't be a bounce dive!

Sorry I should have said: "Planned staged-decompression dives where there exists a statistically very probability of being bent (or worse) if said required decompression stops are shortened or omitted." As opposed to: "a deco dive where there exists statistically minor chance of being bent even if said "safety stop" is omitted." However to make this easier we simply say deco or non-deco dives. :rollface:

I knew exactly what you were alluding to and was just messing with ya. I do personally take a very different approach to many generalized thought processes however, which is why it pains me so much to ever hear anyone refer to "reefkeeping" as a hobby... It's not a hobby, IT'S A LIFESTYLE!
The difference is actually quite huge as with a hobby you can simply stuff whatever it is back into the closet and dig it back out 6 months later (like scuba gear for example), but the living breathing cell respirating animals that dwell with your reef tank require constant daily care, which removes them by definition from the status of "hobby".

them are some wise words! Thank you, you have helped me on here before with diving related topics.
First question: I simply would enjoy the ease of knowing, here is my exact surface interval, here is my conservative bottom time left, oops im floating up a bit at my safety stop and it beeps at me, oops im chasing a turtle and its time to head up (not that id chase a turtle for a picture) , doing an altitude dive, my AOW class taught me how to calculate it but hey if my computer can do it...I know how to do these things and I plan on always doing them but It would be nice to have a second "opinion"
Second question: I don’t want to spend that much, $300 seem right. Right now im just getting comfortable with dives under 20M and the few I have done I loved. But I figure if I make sure I know 100% (attempt to that is) what the "plan" is extra gear cant hurt. Minus the one time I pulled my knife out and cut my leg putting it back in :idea:
I am pretty green when it comes to diving, and have had some bone head accidents but it wont keep me outta the water because I really enjoy it.
oh and to round out your questions, I think messing with gear and tech stuff is fun and pretty cool haha
thanks again for the advice
Oh, my pleasure, my friend!
There's not much else in the world I'd rather talk about than diving. You joke about the bottom timer with the slate attached to it... And I see the humor in your joke, but that's exactly what every "technical" diver I know of does. No kidding.
...Which is very interesting, in retrospect... The "recreational" diver dives a computer because he thinks it's "technical," but the "technical" diver doesn't actually dive a computer - ask him, and he'll tell you that they're "recreational."
...Which I suppose, then, actually makes them "poseur-technical."
That said, I love them for logging dives, and use them as a bottom timer and depth gauge... The way most people I know do. The NDL part of the computer I have found to be inaccurate or misleading, especially if I'm doing things that the computer doesn't account for - like multiple mixes, mixes not able to be programmed, deep stops, or whatever.
Besides, when you do enough diving, you'll find the NDL readout redundant anyway. Most divers already know where their NDLs are, with alarming accuracy. It's not that they're geniuses, it's that NDLs - even on sophisticated computers - are usually determined as a function of "The Rule of 120." That is, the depth plus the time = 120.
For example, if you're diving to 60 feet, you can spend 60 minutes. 100 feet = 20 minutes. 40 feet = 80 minutes, and so on. For multiple dives, spend 1 hour at surface interval and do the same calculations using the Rule of 110. Simple.
Go hit your tables and see how that works out. It's a bit conservative at the extremes and a bit liberal in the middle. But if you know that, then you can pretty much have a pretty good idea of what to expect for your NDLs without even looking.
...Which should never be followed to the letter anyway. You should never know for sure if your NDL is 3 minutes or 4... That's too close to the edge.
After crunching on the Rule of 120 for a while, it'll make you wonder why you ever wanted to blow $300 or more on a computer.
Depth gauge? Yeah, you need one. Dive timer? Yeah. Electronic, downloadable logger? Love 'em. That they come all together if you buy a computer? Priceless.
...But buying a computer and diving on it's numbers and simply going up when it tells you to go up is a bit like driving a car without ever looking past the speedometer... Or trying to drive using a GPS instead of looking through the windshield.
The dive computer is designed to be secondary to the computer between your ears.
Yeah I know, that's why I did the :lolspin:
Hmm, my scuba gear pretty much sits in my kitchen year round once it's dried off.... set of doubles under the counter, one set by the door, deco's under the counter, regs n'stuff in the milk crate sortofoutoftheway.....Why lug all that downstairs when it's just gotta come back up next week? I guess diving is a bit more that a hobby for me :bounce2: IMO, YMMY, etc, etc....

FWIW:and just so know actual Emo Boys are offended, this is an inside joke that plauged SeaJay all last week!!! No he's not an Emo Boy, but it isn't because he wasn't trying... Emo just didn't exist when he was a kid!^ I'm tellin' ya, the dudes pretty damn smart for an Emo Boy! :lol2:
<-- Thinks we need an emoticon with guy-liner, just for SeaJay!
<-- Is probably going straight to hell for this!!! :blown:

Hahahahaaa!
"Me emo?" Ha! I think we've ALL still got black fingernails, Trent Bleedingwrists.
...And I'm proud of my guyliner. Goes with me bringing my own toilet paper into the hotel. (Who uses that scratchy stuff, anyway?)
Who'd have ever thought that commercial divers would have black fingernails and a preference on toilet paper?
Oh, my pleasure, my friend!

I pretty much agree! That's how I dive. Of course you do need two of them btw :eek1: That said I would, however, love a Liquivision X1. Now that is a computer I could actually use (with proper backup tables of course, always). It's worth it just for how easy they are to read. Oh, and if I found $1600 just laying around....

"Liquivision X1?" Never heard of it. Had to to a Google search for it...
http://liquivision.com/news.php
I'm confused about the Jerzy Blaszczyk "record" of 140m. CCR divers have been diving to nearly 900 ft - 270m - for almost half a decade now. Where does this cheeseball get that 140m is some kind of "known record?"
Why is there always so much difference between "marketing" and "the truth?"

Hmm, had to go read that part myself. I had to read it twice. What they are saying, I believe, is that in that particular cave system no one has ever penetrated that deep. I don't know anything about that system so I can't comment as to its difficulty/how far back you have to go to get that deep.
The great thing about the X1, imo, is that it runs v-planner live. I was also able to -read- not just see, a friend's who was on a hang 5-10' below me (off Long Island, btw, not in nice blue water) it was so bright and clear. It actually looks - underwater - like is does on that page you linked to. Again, nice to have, if I had a lot of extra cash

Ah, I see.
For a really impressive resume of cave-diving records, look no further than the WKPP:
http://www.gue.com/?q=en/node/791
Read the article. 26.000 feet is about five miles of penetration - without a computer.
Bushman's Hole (cave system) in Africa is the site of the deepest record dives, I believe, at 270m (891 feet).
...Which may mean that this guy Jerzy Blaszczyk is diving perhaps deeper than anyone has ever dived THAT CAVE or perhaps longer than anyone has ever dived THAT CAVE, but by no stretch of the imagination is it some kind of record.
If that's a "record," then I know people setting "records" every day - there's a lot of people all over the world who add line to the "end of the line" in caves everywhere.
...Not to poo-poo this guy's accomplishments (or intended future accomplishments, since it hasn't happened yet) or anything, but that's not fair to people that really DO hold records.

To be perfectly fair, they never claimed this to be any kind of "record". They simply said this expedition was going to attempt to push past the deepest known dive at the site.
Yes, yes, I know about WKPP, it is impressive.
I'm really not big on any "record" that requires a hundered support personel, underwater habitats, and the like. At that point, IMO, they may as well be commercial saturation divers, but without actual proper chambers on site. I read in a recent issue of Wreck Diver Mag. about some idiots :wildone: doing a record "wreck dive" in some lake in Italy. They all would all have died without the support crew. Idiots :fun2:
Personally, I'd be happy to make it to the Doria in a couple years :bounce3:
