When Gary Yamamoto designed the Senko in the early 90’s, he had no idea he was changing the future of fishing. Now it seems that every company has a similar "do nothing" copy of GYCB's creation, but none have figured out how to make one quite as effective as the original. Over the ensuing period of time, the original Senko, available in four-, five-, six- and seven-inch sizes, has been bolstered with two-tone and laminate models. There's a Senko in the lineup for every possible application and for every angler, from the first-timer to the tour-level pro. Whether you fish it weightless, wacky-style, Texas-rigged, on a Carolina rig, or on a shakey head or flipping jig, this simple slab of plastic will revolutionize your game and increase your catches. 4"The 4"  Yamamoto Senko is not magic, but it's close. It's one of the most productive bass lures in the world. Bass can hardly resist the Senko's unique horizontal fall when fished weightless or wacky style. Not only does the Senko have incredible fish-catching action, but it casts like a bullet and gets into the strike zone quickly.

There's not a big bass out there that wouldn't love to whack a 9X. Why deprive them? Weightless, it can still get down fast in the productive 10- 20 foot depths than most bank beaters bypass, and the 7X makes a great night fishing bait...if you're not afraid to battle scary monsters in the dark.5 pack
