Even tough-bite crappies, perch and sunfish don?t stand a chance against the IMPULSE? Helium Stonefly?s natural, slow-falling action. Fish it alone in shallow water or beneath a dropper spoon to reach deeper fish. Comes pre-rigged with a 1.6-inch IMPULSE? Stonefly body with dual antennas, a multi-segmented body and lifelike legs, so there?s no need to tip this jig.
