Question Shoulder vs butt dump

[yaml]

why don't more bcds have a right rear shoulder dump? versus the much more common left lower front dump?

 

[fred32176]

Scubapro BCDs have an orange button and gray button on the end of the corrugated hose. The orange button inflates. The gray button or pulling on the corrugated hose will release gas. They also have a right shoulder and a left rear dump valve. I don't think I have ever used the right shoulder dump valve in water.

and I’m sure there are lots of different stories about BCD failure that don’t involve shoulder dumps.

Sounds like they were also over-weighted.

Sounds like they were also over-weighted.

Perhaps a little, although I think most (cold-water) drysuit divers would struggle to keep comfortably out of the water on the surface with an empty BCD. You can’t keep much extra air in your suit when you’re vertical bobbing on the surface, and your head is quite a lot of weight to support out of the water.

 

[PEDiver]

since that the vast majority of the time, a diver is either vertical or prone

Well there’s your problem.

 

[The Chairman]

Perhaps a little,

If I'm any more than a "little" overweighted such as with double steels, then I'm sporting a dual bladder BCD. There's just no need to put your safety and/or comfort at risk. I would rather dive a balanced rig, but no can do when I'm in the caves.

Well personally I've had enough of this bending your head back horizontal stuff

scuba diving trim
verb

to scuba dive at a trajectory or body angle that is most comfortable for the diver
allowing, a mostly unimpeded view of all around, without resorting to contortion
or unnatural bending of ones neck, and allowing easy use, of the shoulder dump
anytime it is required, with the body, at an angle of less, than fourty five degrees

Yes I'm adopting seahorse mode, thing is even with a 28lb weight belt and 9lb plate

I still can't do it


How are those trim weights working for youse all

I’ve had dive buddies with right-shoulder dump valves have the pull toggles get entangled underwater,

Get rid of the toggle, just leave the cord with a stopper knot that it can’t go back through the guide.

One thing to bear in mind is that any problem with a pull-cord dump on the shoulder will completely deflate your BCD on the surface. On two separate occasions, I’ve had dive buddies with right-shoulder dump valves have the pull toggles get entangled underwater, which held the dump valves open so that they couldn’t inflate their BCD on the surface.

Very strange, why did it stay open after it was cleared. I’ve actually found the rear kidney dump to be the most likely to foul going through a restriction so I cut the cord short, get rid of the toggle and put a small stopper knot instead, I’ve still had to cut it when it got caught in plating.

I knew a cave instructor that would twist those balls around a cave line if you ever got close. Like most cave instructors, he was a sadist. I loved him for that.
