On a trip not so long ago we assembled our BCDs and my spouse says the corrugated hose connection is leaking. Yup so is mine. After the last trip I disassembled the hose so the bladder could dry out. So not to lose the gaskets I set them aside. Guess what I forgot? Fortunately, the live-a-board had spares.While you are thinking of spares one of the most common failures in dive equipment is the BC inflator. Either the rebuild kit and the tool or a spare unit makes sense.
As for the OP, we rarely travel with spares but when we do it is usually in the form of deco regs.
