Hi guys. Before I want to spend pellet money, I first want to hear if it would work in the first place. We have a fishing spot at a river, and I want to see what size fishes are swimming around. But will a camera actually see anything past half a meter in say 1.5 meter deep river water? Can I use my normal camera in a waterproof housing, or will n true underwater camera be better? I'm thinking there might be focus issues with a normal camera perhaps.
