So, after months of scubaboarding and acquiring equipment (God, that was a serious expense!) the wife and I finally did the classroom/confined water dives this past weekend.

Although our BCs are weight integrated our instructor insisted on putting weight belts on us.

First of all, the BC's and weight belts do not fit properly together. The BC was either pushing down on the belt or floating up on me with the belt on. After day one I swore NEVER to wear a weight belt again as long as I lived and TOLD my instructor I'd be using weights in the BC.

My wife, go-along/get along type that she is tried sticking it out with the belt even though she made the same complaints to me later Saturday night about fit and comfort that I stated above.

More on this later.

Aside from the belt/BC thing, I was flopping around like a drunken sailor. Every slight "current" in the pool pushed me over and I'm flailing dangerously (of course it didn't help that there were 13 people in a pool that was about 50' x 15'. Eventually - like near the end of a 3 hour stint in the pool, they figured out that I was improperly weighted. Ended up putting 26 pounds on me. Well, I was more stable, but could hardly propel myself.

At the end of the ordeal, I talked to my wife who said she was going through the same thing.

And so, we just resolved to "get better" the next day.

First thing I did upon arrival at the pool on Sunday was to start filling my bc with 26 pounds of weights. Got a scowl from the instructor, but wasn't about to back down. I only have to see/deal with that - fine individual - a couple more times. I'll be going elsewhere for AOW. Bet on it.

Things went so much better for me! Felt MUCH more in control, comfortable and happy. Until it came time to doff the weighted BC underwater. Once it was off, I started losing balance and the tank/bc. Not about to make the instructor "right" I followed it, put one arm in, rolled to get the other arm in, and kept my momentum going as I was taught in countless martial arts classes, until I was standing and reattaching the harnesses. Nothing she could do except give me the "ok" sign and shake my hand. God, that felt good!

Now as for my wife, there was a different story.

She tried to do what they wanted and had the same problems as on Saturday. Out of control and uncomfortable. Finally, 30 minutes into the class, she decides she can't take the belt any more and begins filling her BC. After which she too was much happier, more stable and more comfortable. (BTW we were the only 2 in class with our own equipment, the dive store rentals everyone else used were non-weight-integrated BCs.)

When it was her turn to doff the BC, she damn near floated to the surface. Eventually, she was able to accomplish the skills well enough to get by. We'll have to work on that in the pool together as there may be a time in the future when we'll need to do that for real.

Then it was back to class for the last written tests. One piece of advise to those who are planning on taking the OW course: Get the eRDP calculator! Best $25 you'll spend for the tests! Yeah, I spent 3 days working out how to use the card and got it down. Then at my wife's behest, I bought the calculator. Using that, we finished our tests about 20 minutes before anybody else. LEARN how to do it without, just in case your batteries die, it slides off the boat into the water, or your dive computer goes belly up, but get the calculator for the tests!)

So, from what I've been told, the worst is over. Next weekend 6 boat dives: 4 for OW certification, 2 for PPB.
 
Hi, Canis Major, I posted this on SB2 regarding Catalina+boat diving...both of you enjoy yourselves!



"Well, of course, being shoredivr, I think of shore dives first...

I dove off a Catalina-based boat, the King Neptune I think it was, and had a great time. There's so much to see underwater there: the Garibaldis are just the most obvious fish.

When you're in a pool doing skill sets, there's nothing much to see except the other students. I remember my first open water training dive (in Roatan)
kneeling on the bottom, waiting for my turn to do a skill, looking at the gravel, and noticing that one piece started to move, then another piece, then another: they were little hermit crabs! I was instantly hooked: diving was cool!

I'm sure others will chime in, but here's two tips for boat diving:

get permission from crew or captain before coming aboard with your gear: they may not be ready for you yet

always listen to the pre-dive briefing, you'll hear stuff that's important to the boat and operation procedures, plus information about the dive site itself

Diving in kelp has a few tricks, your instructor will have tips on what to do if you get entangled in it: I was told to stop, get buddy's attention, back up slowly, get unhooked by buddy or unhook yourself from the kelp; snap it if you can't get untangled - individual fronds break easily; don't turn around to see where you're caught because often this just tangles you up more.


And there is a shore dive on Catalina: Casino Point Underwater Park...."
 
Thanks SD!

So, tell me something.... I've heard that beach diving is "no fun, you don't get to see anything and it's dangerous." This from my instructor (and if you read above, you know the high esteem in which I hold her!) so I take it with a grain of salt. So what's the allure of being a "Shore Diver?"

Please... tell me about it. I'm intrigued by it, but if you don't see anything, what's the point? Thinking of joining the group at Wrinkles beach dives in La Jolla in Sept. but wanted to know what to expect.
 
26 lbs of lead in a pool???

If you have 26 lbs of lead in your BC, you can put your own gear on.
We split it up, try to keep a max of 10 lbs in your BC and the rest in your belt.

Yeah, well, I weigh 240 and am wearing 7mm suit and hood, 6mm boots and 5mm gloves.

Thinking about a weight harness. Anybody ever use one of those?
 
I am not an expert, and I am sure on individual basis it would change, but 26lbs in pools sounds like to much weight to me.
Maybe some one more experienced would have different opinion.

I completely agree and would have said something except for 2 things:

1. The belt thing put a pretty heavy wall between us and I really didn't want to generate any additional animosity between us.

2. All I have to go on is what I've read vs the stability I felt when they put that much on. I think they over weighted my wife as well - she's no where near my weight - figure 150 - and they loaded her down with 22 lbs!

And this is the person who's going to be teaching us PPB next weekend! If I hadn't already paid for the class and if we weren't going to be there for those 2 extra dives anyway, I would have gone elsewhere for the PPB class!

Also, aside from the comfort angle regarding the belts I would always presume that someone with thousands of dives would know better than me. I may have "slept at a Holiday Inn last night" by being on Scubaboard for the last 7 months but I don't believe that I know best about weighting or anything else in Scubaland.

But, on the other hand, the world did stabilize after they put that much in and according to the Adventure Dive Manual (for the PPB) I should have about 30 lbs for saltwater

7mm suit w/gloves and & hood - 10% of body weight + 3 to 5 lbs = 24 + 3 = 27 lbs (I am The Big Doggy after all).
Add 8 lbs for salt water (I think that's a little high, but I didn't write the book) = 35 lbs. Subtract about 4 lbs for my steel HP 100 tanks at 500 psi = 31 lbs.

For my wife it would be: 7mm suit - 15 + 3 = 18 lbs
Add 5 for Saltwater = 23 lbs
Subtract about 1 lb for her tanks (different brand of HP 100) = 22

I'm anxious to hear your thoughts about how we should weight for our OW dives!

(I need a shoulder shrugging icon for being unsure how to proceed!)

I've got a little bit of experience, with 67 dives mostly in the gulf with some in the Florida springs. From my personal experiance with your weight and all the neoprene 26lbs isn't that bad. I tried a 7/5mm full suit (I weigh 220lbs) and I needed about 26-28lbs. I usually dive with a 3/2mm in the winter and a shorty in the summer and for me 12lbs is perfect. However, I do have a new 5/4/3mm full suit that I'm itching to give a try to see how much wieght I'll need though I suspect I'll have to have around 18-20lbs. In short the more neoprene the more lead you'll need.

I always recommend for people to rent gear for their first 10-15 dives until they figure out what type of gear will work for them. However, the first thing I'd get is a wetsuit after the mask,fins,snorkle,etc. Then later on get the BC and everything else. But as you get more confortable the amount of weight you need will decrease to a point and after that it'll always be the same.
 
froggs:
Damn...with a 7mm jumpsuit, hood and gloves, what's the water temp of the pool???

Wasn't nearly as bad as the air temp! 83 at 9:00 a.m.! It was actually quite nice in the pool. Can't wait to find out what the ocean temp feels like. Should be really nice after sweating for 15-20 minutes in the wetsuit! :)
