My dive club went for a dive today in the local quarry. On the second dive one of my buddies lost signal on his left tank. After the dive it was found that the battery compartment to the transducer (oceanic style) was flooded (freshwater). Any insight Or experience with resolving this issue? Hopefully the battery compartment is sealed from the board, but it’s hard to tell. Im hesitant to recommend disassembling the entire unit, because those side screws look really easy to strip.
