On a large shad lure designed for pike, a small weight maintains a slow descent for fishing in shallow water. Increasing the weight accelerates the sink rate and takes the lure deeper.
Screw it into an area with sufficient substrate, then check the lure’s trim by retrieving it slowly. The Mass Add can be used in conjunction with a Lure Fixer and a stinger; these accessories should be selected separately based on the lure’s length.
