Yo-Zuri’s Bonita 1157 Series high-speed trolling lure features patented color-change technology on top and a smooth scale pattern on the sides. Its tight swimming action is especially effective on wahoo and tuna. The patented body, flat-forged stainless hooks and ball-bearing swivels and through-wire construction combine for maximum durability. Two sizes cover a variety of conditions. The 6-inch, 180-gram model trolls at up to 10 knots; the 8-inch, 310-gram version up to 15 knots.
