Hey Ali cabe tie a fishing net float to it if you can!
They were doing great deals duty free on Sony Action Cams see if Angie can get you one coming back from OS.
Thanks Phil, but I won't have the funds to buy a replacement anytime soon, not sure if I'd bother with another Sony anyway (even if I've still got a bunch of mounts/accessories that won't fit anything else). The picture quality is great, but the camera heats up way too quickly and I've had all sorts of problems with fogging. Tried anti fog inserts, paper towel inside the case, blasting it with the air-con in the car before closing the case to dry out the air inside (particularly on humid days), and storing with those silica gel packs they use to keep moisture out pretty much anything these days. But the heat the camera generates just seems to be too much when the outside of the case is by water (even the relatively warm water we get here). On a good day, I'll get 20mins max before fogging (usually not running constantly) and a bad day only 5-10mins.
Will probably look at an iON Air or maybe GoPro if I decide to replace it down the track.
