The Stingray Diving Weight is a true multi-species inline weight and engineered with walleye anglers in mind. The unique design of the Stingray take a big bite out of the water column and highly versatile. Use them with crawler harnesses, trolling spoons and small or shallow diving crankbaits. The big lip on the Stingrays get the bait of your choice down to where the walleye are. As water strikes the top surface it forces the Stingray downward. When a fish gets hooked it will force the nose upward causing the Stingray to go to the surface & takes the fight out of the Stingray.
