My first dive after completing my OW and I’m at 42’ diving on the wreck of the Antola in Aruba. I’m starting to get a bit buoyant so I give the inflator a tug to let some air out of the BC. The inflator hose came off the inflator and the pin holding the OPV cable slid out releasing the cable. I need to head to the surface with no way to inflate the BC on the surface. Luckily I surface an arms reach from another anchored dive boat and got a hand onboard.
