Mmm, yes. The troll game is strong and funny with this one.

Seriously though - Cellphones, Go Pro, Go Pro Session, something cheap from eBay. Nikon makes a $110 waterproof point and shoot.

If you want to spend some coin, the Nikon AW-1 was pretty cool mirrorless weather (read as NOT WATER) proof crop frame camera. Pretty much anything Sony these days (5000-series on up to the A7- series). Canon and Nikon too, if you prefer traditionalé.
