| narked, i think you mean the OPV. as nick said, the ADV doesn't "click".
my OPV is shut when doing pos and neg checks but i open it 15 "clicks" for the dive. also, as nick said, very difficult to operate the OPV ourselves.
as a matter of interest, was the OPV secured properly in the case prior to the dive and / or could it have become "unseated" upon entering the water and therefore got somehow "jammed" inside the case? |
