Drysuit dump valve (bare)

[Troutmaster]

I have the valve all the way open and I may be a little light as well, I am going to try the recommendation of right shoulder down, left arm up. I was going from horizontal to vertical to a few degrees past vertical to get the valve where I thought it needed to be to get the air out.

I think the sugestions here are better than the way I was doing it. Thank you to all the SB folks, my first post was very productive!

The water was alittle chilly that day (36 deg F), I was in the water 90 consecutive minutes and with diving concepts mid weight fleece over underarmor "cold gear" I stayed toasty except my fingers, maybe dry gloves are in my future.

Even through a thick hood, if you listen carefully in-between breaths, you should be able to hear the bubbles leave the exhaust valve. You should not have to break trim to dump gas from your suit; rolling slightly to the right is all that's required.

I have the Viking bayonet-style drygloves (Atlas 620 orange gloves worn with midweight liners). They mount very nicely to the Bare bell-style latex wrist seals. Not too expensive either (about $100). I ordered them from Bob3 here on ScubaBoard. Great guy to work with.

Originally the OP mentioned possibly moving the valve?? maybe you guys can correct me if I am wrong, but I seem to recall the valve gasket being welded into place on the nexgen. If memory serves me right, it is a hard-ish plastic sealing surface that is inserted into the NexGen material and so just patching (which involves sending the suit back to the factory for welding anyways) and poking a new hole like on a neoprene suit is not going to be ideal....

just thinking aloud

tregrrr, good thought. I am almost certain now this it a technique problem, not an equipment one.

I am making a tank size change (waiting to get it back from hydro) and an undergarment change. As soon as I have those items in hand I am heading to the pool to weight out. Then I am going to lay on the bottom and put air in, and vent air out, then repeat until I get it figured out.

As soon as the ice melts I am going to do the same in some open water.

what kind of clothing are you wearing underneath? i found that soft shells don't let air pass through as easily as fleece. The Bare undergarment has a few rivet holes in the arm area to let bubbles out better. I also found that if the bcd shoulder strap is too tight it could restrict the movement of air in the suit. if all else fails, i do the 'chicken wing' and difficult bubbles come out no problem.
