The majority of our divers using this BCD are, as well, diving dry suits. It's really a matter of choice on which you use for buoyancy underwater. There are two schools of thought on this. I for one, only use my dry suit for buoyancy once I'm off the surface. There are some that add only enough air to the dry suit to keep the squeeze off and then use the BCD for buoyancy. For a wrist dump, it may be a little more cumbersome. For a shoulder dump, which are the majority of suits that we see, it's really a non-issue, because when you raise your elbow to dump the suit, your hand is still in position to dump the BCD as well.
