Are BC dumps really needed?

[james croft]

I could get by without them.

Knock it off you guys, you made me cry like a baby by making fun of me(my) polls!!

Didn't anyone tell you its the motion of the ocean not the.....errrr....never mind.

The inflation tube is fine if you're vertical. If you're horizontal, it requires some shifting to get to air up to it to dump. Much easier to reach back to my rear dump.

Every BC needs one Over Pressure Valve. It keeps the bag from bursting. If you have a means to power inflate there is a real risk of popping the BC without an OPV. More than one is unnecessary.

You don't see OPV's on oral inflate only devices such as a safety sausage, because it's pretty hard to pop one with just your lungs.

I'd be lost without my back dump.

If the question is the rapid exhaust/pull dump at the top of the corrugated inflator hose they aren't needed and is just another problem waiting to happen. As most have said the rear dump should get the most use if you're diving horizontal.

Rear dumps seem particularly useful if for whatever reason, your bouyancy has gotten away from you and you are now over-bouyant. You can then simply swim on a slightly downward angle and adjust your bouyancy using the rear dump.

Bottom dump gets 90%+ use for me, if i do need a top dump my wing has a pull dump on the right hand side.

I very rarely if ever use the press button hose dump and no way am i using the hose pull - seen too many detach/snap.

Just as in nature, we all need a dump valve, and it should be at the bottom (below the bladder).

H2Andy made me say that.

If you have proper trim it's easier to use a bottom dump than anything else.

I read a comment of BSAC (?) when I googled bc dump valve... a british member said that he and his diving buddies cut the cord off their dump valves as ?? something to do with their being caught in the open position??

He claimed that he has more control over how much air is vented off by using the corrugated inflator hose... thus has better control of his ascent ??

In the confined environment (which I dont' do) do cave and wreck divers find the dump valve more functional than the corrugator hose??
