Bowfishing lights help you in more ways than one. The most obvious is that they help you see the fish you’re shooting. Even if the water is murky, the light can create a visible shadow if a fish swims under it. Secondly, lights can actually attract fish, too. Think insects coming to a lamp. Last, a light can simply help you move around your boat or dock. You can change out equipment, nock an arrow, etc. more easily.
