GoPro Hero4 Session BASS POV - Dave Mercer's Facts of Fishing! - Pro angler, host of Facts of Fishing THE SHOW and Bassmaster Elite Series emcee Dave Mercer catches a Great Lakes smallmouth bass and captures the release with a GoPro Hero4 Session BASS POV! The big question is how did we do the Bass POV view shot? This unique shot was accomplished using the super small GoPro Hero4 Session and a custom made break away fish mount. Once the fish reaches a set distance it releases so we can get the camera back.
