They need to bring out vapechains or something to strap to your wrist or jacket or whatever for fishing. I remember losing a few packets of cigarettes over the side of the boat when I went bass fishing in the past.. if that happened to one of my mods I'd throw stuff.
I've lost one mod overboard and one scale and one brand new iPhone 6+ (12 hours old)... managed to retrieve the scale because it floated, the mod was retrieved but never really worked well again but the Nautilus Mini went on to serve me a long while still... it actually may still be in service because I piffed it to a mate and he still uses Nautilus Mini's.... the iPhone is still in 25' of water...
