Some prefer to remove the knob so it can't snag.fisherdvm: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??
fisherdvm: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??
The inflater valve dump does have more finesse than most pull dumps. With practice you can feather the pull dumps just about as well. Use whatever you are comfortable with. During the dive I loathe needing to lift the inflater to dump and always use the back bottom dump.
