To understand the Kwikfish Xtreme, you must first understand the origin of the original Kwikfish. During the period of its design, lure prototypes included laborious hand-made samples from which final designs were created. Imperfections, however slight, were a fact of life. Kwikfish Xtreme designs are born as a product of the latest manufacturing techniques. Featuring finely tuned body parts, the lure actions are precisely controlled. Kwikfish Xtremes dive deeper and run true at a wider range of speeds than their predecessors could ever accomplish. Trolled or back-trolled, Kwikfish Xtreme models offer trout, salmon, steelhead and walleye anglers the most advanced wide-action lure ever created. Length: 3-3/8" Diving Depth: 12&'; Hook Size: 4 Non-Rattle Fixed eyelets (not screw eyes) No tuning required Side-to-side body construction Wide, slow trolling action Round bend treble hooks
