Trolling for walleye with a spinner rig and night crawler on the downrigger and underwater GoPro Hero. It proved difficult to entice a bite so close to the camera housing and canon ball but two walleye were brave enough to take the worm on camera. The water was a bit murky but you can still see what is going on as the walleye move in and hit the spinner rig with trailing night crawler in 20 feet of water. I'll be trying to get more footage of walleye... I'll just have to find some clear water and crazy walleye action.
