Does this BC product exist?

Walter....... I think this picture pretty much defuses any arguments about streamlining and it's a jacket. Go figure, huh!!!

I dunno Don... it doesn't look all that impressively streamlined to me. The console and what I presume to be a cummerbund adjustment strap are hanging out of the diver's slipstream creating drag, and that thing above the tank (possibly a cam strap) is doing the same.

It's not bad streamling, but it's not what I'd call "bragging good".

tell ya what Walter, it isn't and if you PM me your size and address I'll have a loaner sent for you to trial.

Sounds like a deal to me. I'll be happy to test dive it.

I know it's been said before, but that photo ain't exactly a poster child for excellent application. Having a tank sagging down around my knees like that would bug me no end. Single tank straps are OK for AL80's, but they don't support larger steel tanks very well and have a tendency to loosen up at inopportune times. And the hose routing is hardly what I'd call "streamlined".

I know she's a professional DM in Cozumel and all ... and for that application it's obviously just fine. But like any piece of gear, you have to consider the application ...

Bob, In my post I gave consideration to the application didn't I? And while I'm not trying to blow smoke, you and Ash are two of those who could help someone wanting to get into tech.

Okay you guy's......... I've shown you mine so show me yours!!! Put a picture of a bp/w showing better streamling and I'll stop flashing mine.

It's a Sherwood Luna. That was my first BC and when you're diving with more weight because of thicker neoprene, it puts you in a heads up position with a lot of air in the shoulders. It's the diver's skill and lack of lead which makes it work in the photo.

Dacor made the seachute many years ago. Wing in back Horsecollar in front, separate bladders, pain in the butt to put on & take off.

I have one of those from ScubaPro.

If you're face down, the air stays in the back of the jacket, keeping you horizontal. In fact, the larger air pocket is lower down, so it tends to not tilt your head up.

If you're vertical and lean back, most of the air goes to the sides and front, keeping you on your back.

Maybe someday the BP/W folks will convert to this superior air-cell geometry.

I've been reading about the different types of BCs and I understand that many people perfer bp/wings over vest because bp/wings have less drag. However when on the surface, the bp/wings type tends push the diver's face forward , but the vest will not.

Does anyone make a BC where you can control which bladder the air goes in to?

I'm thinking something with a bladder in front and in back. The diver would fill the front bladder when at the surface, but be able to deflate it for less drag under water and only use the rear bladder for bouyency compensation.

Well, I can't tell from that photo. Some vests are steamlined, others are not.

All overweighted divers will be heads up regardless of the BC. The angle and upward thrust of the kicks is what keeps them from sinking.

Not hard to be streamlined when it's empty...

It's easier to keep good trim with a backplate when you must carry additional lead because of thick neoprene and those silly AL80 tanks. The Luna jacket puts a lot of air in the back of the shoulders because it is anti-squeeze and not as bukly in the front as some other jackets.
