I retrieve the gopro from the lake and find out what it have seen during the days at the bottom.

You may try to put some selicagel inside of the can with batteries to avoid moisture condensation. The best way is to close the can on the shore - otherwise you will get moisture inside of the can with sea air - and then it will condensate as batteries are heating while running.

I try to close it on land before i go out, but it have leaked anyway so i have to poor the water out and try again. I don't want to seal it by silicone or something, i wan't to be able to open it. I did have a bag of silica gel in it the first time, but it got soaked, so i just go without it now. It seams that a jar is harder to get waterproof when its been used underwater, i have to open and close it a couple of times now to get it waterproof. (even that i cleaned the lid, and screwed it on hard). In the future i think i will not use a jar, just make a waterproof battery pack.

@@petleh82 sounds like a good idea. Here is what i do to waterproof cavities like jar : ceresit C14 solicone (its flexible enough to remove it when needed to open a box and perfect for sealing); epoxy & hardner to cast battery alone (just keep leads out the rest is 5mm around outer dimentions by polistirol forms).

What was the light flashing during the last night episode?
