Nothing life threatening, some annoying, some "duh" :
Flooded light, switched to backup
Flooded camera (within first minute of the dive): went back to the boat, gave the camera to a crewman, and said "don't put it in the camera tank, it's toast".
Leaking LP inflator hose at the connection to the valve (1): disconnected it, reattached it, fixed.
Leaking LP inflator hose at the connection to the valve (2): disconnected it, reattached it, it still leaked. Finished the dive with it disconnected.(note: the dive was at a site where the hard bottom was at 27 ft.)
Cable tie that holds the mouthpiece onto the reg snapped/came loose on giant stride entry(?) swam to boat platform,crew replaced it, as I held onto the dive platform.
