I should be getting a "Nautilus Lifeline Marine Rescue GPS" today. I may not need it yet, because I mostly dive in lakes with no current and decent boat-traffic, but I saw a killer deal pop up. Plus, I might not have time to PLB shop whenever I randomly decide to go on an ocean or vacation-dive. I guess it's like insurance you only have to buy once.
I've read they occasionally/rarely flood and to be careful to not over-tighten the screw, so I was thinking of double-bag-vacuum-sealing it after putting some batteries in it, and just cut it open when needed or to check functioning occasionally. Alternatively, putting it in a 2nd housing depending on it's size.
Since this thread is 121 pages long, does anyone have a good recommendation for SOLAS fabric or tape? I can obviously grab a random brand off Amazon, but figured people might have a favorite or tested one they'd recommend. I'm also good with a sewing machine, so fabric preferred if possible.
