I have a similar issue at the surface
How does a crotch strap help to keep you vertical?

I switched to a LP Steel 80 and it sets me up perfectly at the surface and I'm not having any difficulty under water either. Now if I have to rent an Al 80 for multi dive days I end up with the original problem again!

It helps to counteract the effect the usual body contour has on the scuba unit (tendency to angle the bottom outwards). It also helps to keep the BC from sliding up which tends to accentuate the effect of pushing the diver on its face. At least that's how it has been explained to me.

To counter the face forward "problem" with back inflates, simply do as simbrooks said - on the surface, lay back against the BC like a recliner chair, with your legs in FRONT of you. Lay on the surface, don't try and float vertically with your legs beneath you, knees bent & fins behind you. Put your fins in front of you.

Roo's got it right on the money here ..... Just sit back in your Lazy-Boy and prop your knees up in front. Just lean back a bit flatter on your back for those long surface swims .. it puts most fins at a better angle in the water than face down with a snorkel.

If your back inflate is faceplanting you, then you're doing something wrong.

Good advice from everyone.
Thanks!

I'm going to use crotch straps because the BC actually does move around on me. The straps will help with that because it tends up move up on me.

I'll put two small pockets on the back of the thing and put some small weights there. Draw an imaginary cross on the back of the BC, I assume that the weights should be slightly above the horizontal center line..??

As a side note, I like this BC because the bladder is entirely in the back and is really stable at depth. I've tried some of the other jacket style BCs and they tend to squeeze me when inflated. Granted, one shouldn't have so much air in one that it does that, however, I could tell it was getting tighter, and with an already snug wetsuit on, I didn't like it.

The next step is finding the straps and pockets then learning how to attach the darn things. Any ideas?

Incidentally, I'm so looking forward to May 22nd. The TA Dive Club (not a member yet, however, will be by then) is going to do the first club dive at Circleville Twin Quarries in Ohio. I can't wait!!

Again, thanks again. Scubaboard would be nothing without your help!!
