Does anyone have a S/H auto shoulder dump valve they would sell to me? (It's for a sacrificial drysuit which will get wrecked on a gnarly caving project, so no point shelling out on a brand spanking new dump valve.) Push button preferred rather than pull cord; then again, beggars can't be choosers.
Separately, I'm looking for second hand Apeks cuff dump valves. CDG Newsletter 221 (October 2021, page 4) has a note about improvements to the CDG DIY P valve system. I want to make some more of these.
There are a few versions of the Apeks cuff dump but the type I'm after is the one with a back plate which has thick spokes connecting the outer rim to a central point. I've attached a picture which shows one modified into a P-valve.
Many divers dislike cuff dumps, so often swap them for a proper shoulder dump valve. The old cuff dump usually gets chucked in a box somewhere. If anyone can dig deep and help with either request above, please could you send a P.M?
