I have tried to be a better photographer on my fishing travels, buying a nice (at the time) SLR Canon Camera and Canon wide angle lens some time ago, but have found the weight and bulkiness when packing and the fragility of the unit to knocks and water a major deterrent for me. I have tended to leave it at home when traveling on fishing trips and mainly used waterproof point and shoot type cameras, many of which have leaked and have needed replacing.
On a recent trip to the Seychells a friend had a Gopro 3 Black which we used for stills and video and I am completely blown away at the quaility of the pics and videos. This along with the tiny size, minimal weight, plastic waterproof and protective housing which does not leak and does not rust or corrode, I am definitely thinking of going this option.
I am looking at getting the latest Gopro 4 Silver which has a built LCD screen, if Santa (my wife) is listening.
Here are some pics taken with the Gopro 3 Black.
