It doesn t matter what type as long as it fulfills your needs. The range of capabilities is wide. First off, prepare your camera so when you do catch a fish you are not messing around with putting stuff together. I have been guilty of this once before. A concern that can be raised is water getting the camera wet.
Many cameras come with a leather type case that affords some protection.
To keep it completely dry, simply put the camera and case inside a large plastic garbage bag and wrap it up. Hefty TM Steel Sak garbage bags. Once it s wrapped up just store it out of the way in the boat. It is guaranteed that if you don t do this and your partner hooks a good one, and you try to videotape the fight, you will be on the receiving end of an expletive laden verbal attack about putting down the camera and getting the net. In our boat, it is decided to tape after the fish has been netted to avoid the previously mentioned verbal pleasantries.
