Everything that SeaJay says should be taken to heart, because he is a professional diver that logs probably a thousand or more hours (
not minutes) underwater each year!
In regards to doing your 4 OW check dives in Cancun, are you really sure you want to do that..? I mean while it would be a fantastic place to be able to say that you were certified, I would personally rather be DIVING than have to be confined to doing skills tests with a group of other students that you probably don't even know... That said, I would suggest doing your check dives locally, so that you can then use your time in Cancun or Coz more to your favor.
Also, something to consider in regards to classroom stuff spread out over several weeks for 3 hours a week is that it's actually all very basic stuff when it gets right down to it. Oh sure, the 1st chapter of the OW book will scare the bejesus out of you making you THINK that you will DIE if you make even the slightest mistake. While everything that they say is actually true, as long as you're paying attention to your gauges and NDL's (
time -vs- depth) you'll be just fine, and like me wanting more and more and more... I say that because I was just certified in March for OW, but this past weekend I completed 3 more advanced level classes (
Nitrox, Advanced open Water and Night Diver). It was a really rough month of studying my butt off, but I set a goal for myself and I completed it. My instructor said that in all of his years of teaching that he had never before taught 3 classes in a single weekend. Our schedule was so stringent based upon PADI's limitation of 3 training dives per day, which meant that the 1st night dive had to be Friday, followed by 2 on Saturday with the 2nd being precisely at 12:01am to actually be recorded as a Sunday dive. Since I did those 2 dives on Nitrox, I was able to stack them to make it possible. It took some pre-planning on my part as well as the shop staff, but we pulled off a trifecta!
Also as SeaJay stated, be cautious of your equipment purchases too early on, because you may well end up switching gears with your intended diving goal, and what you have now will not work for you. If you only ever want to dive warm tropical waters during daylight with 300' visibility, then you'll be fine with the latest "fashion trends" that your LDS is offering by companies such as the one that "Coral Diver" works for (
don't get me wrong, they make great gear!). However, if you're more like me and you KNOW exactly what you want to do, then you'll want to begin acquiring gear which is far better suited to your needs. Unfortunately, you don't know what that gear is yet, so any purchases at this point beyond the "basics" would be a crap shoot at best.
My goal is to become a Cave Diver, which means that I'll need rugged, utility gear that is modular in concept so that I can quite literally build it out for the specif dives which I intend to be making. How do I know this..? because a few months back when I asked the very same questions that you have, SeaJay told me the very same things that he has just told you and several others here. Since I needed a BC right away to be able to do as much diving as possible since our LDS offers free boat dives on the lake nearly every weekend, I bought a very good used one on eBay for less than what I would have paid to rent one for 3 weekends... Guess what, it's already paid for itself about 3 times over!
I
know my gear, and I know that it won't fail me as long as I DON'T FAIL it!!! This past weekend I had zero issues in regards to the night dives as opposed to those that used rented or even brand new gear, because theye didn't have their fitting adjustments dialed in, couldn't figure out where this or that was placed on what D-ring, and basically had an overall miserable night diving experience.
I dive with a 19cf Pony Tank side mounted and inverted, with mu Octo on it rather than on my primary cylinder, and being the
only diver in our regional "group" to do so, I get asked a lot of questions about my rig. I have setup my gear for MY own purposes which are about 3-fold, but can add great potential benefit to any dive team in nearly any situation because I can reach around and pull a pin to release a tank to hand over to any diver in distress, or even hand over my primary AL-80 and regs while I use the Pony to surface and get additional assistance if necessary... Not only does it sound great in theory, but I've practiced it!
By all "basic" standards, I'm breaking pretty much every rule of diving by pushing the limits and getting ahead of myself, but I am also willing to burden the expenses to do so as well as evaluating each and every situation along the way. I'l also be the first to ABORT a dive if need be, and wrote about doing just that during this past weekends trifecta of classes in the "More Classes" thread that I started.
Basically the best possible advice that I can give is to do what I have done by utilizing the talents and skill sets of others such as SeaJay as a highly qualified mentor. SeaJay and I have not yet had an opportunity to meet, but we have spoken on the phone on a couple of occassions with our first call being a marathon session. I will very emphatically state that his advice has more than likely kept me alive at this point, because I was too gung ho right out of the box. I slowed my @ss down and began paying very close attention to what he had been trying to tell me from day one, and I would consider myself to be a much BETTER and SAFER diver for doing so!
One final piece of advice if I may, would be to "consider" rather than a regular 9-week class session, the possibility of spending a little more for a 1-on-1 session with your instructors(s). I went this route for $100 more, and what it entailed was reading & learning at home on my own, then scheduling to "hang out" at the shop for a couple of hours a couple of times in order to review the chapter lessons and take the tests. The 2 pool sessions were also 1-on-1 and done in 2 evenings at the local YMCA. Our LDS sent several classes of students to Vortex Spring in Florida this past March for a weekend, so that we could all do our check dives with our own instructors that we already knew.
Live long and prosper... DIVE SAFE!
