The Lake Effect 3D Panfish Bump Board keeps crappie, bluegill, and perch measurements quick on the boat, in the ice shack, or walking docks, using a 12' blue-and-white high-visibility layout that reads clean in low light and snowy conditions. The ultra-portable, lightweight floating measuring stick mounts to a boat or sits loose on the ice, making length checks easy when sorting keepers or tracking trophy fish for photos. Its raised bump edge squares the nose of the fish for accurate measurements and the floating body prevents the board from disappearing down a hole during fast fishing.12 in. high-visibility blue/white measuring layoutUltra-portable lightweight floating constructionRaised bump edge for accurate length checksMountable on your boat or use as a loose board on the ice
