The original senko that has most likely caught more bass across the country than any other bait on the market, the Yamamoto 4in Senkos Bulk Packs gives the hardcore angler all the baits they need for tournaments or seasons to come. This bait dramatically changed the bass fishing, capable of a variety of techniques that work across the country. Its simplicity in design may discourage anglers from thinking this bait is much of anything, however its ribbed, salt impregnated body and tapered tail allows this bait to fall horizontally with a natural side to side shimmy action, much like a dying baitfish that is descending to the bottom. When rigged weightless, this bait displaces water and simply drives fish mad. This bait works extremely well when wacky rigged or Texas rigged weightless, however can be used at the end of a Carolina rig, weighted swimbait hook and more. Often imitated but never duplicated, this baits softness, rate of fall, and inherit natural action delivers results!
