The 4" Hog Impact by KEITECH beautifully mimics a craw or a larger insect larva. The arms, combined with the rear pincers, are always in motion, making them particularly enticing for Perch, Chub and Zander. The 4" Hog Impact can be effectively used as a trailer on rubber jigs and it also performs  incredibly well on Drop Shot, Texas, Carolina and other finesse rigs!
