Ideal for pressured water and wary bass, the Shimano World Diver 99SP Flash Boost Jerkbait targets suspended fish with a compact profile and a true deep-diving range of 6' to 8'. A wealth of innovative lure technologies makes this one of the best deep-diving jerkbaits you can fish. The World Diver 99SP's suspending design uses Flash Boost technology to generate continuous flash on the retrieve and subtle wounded-bait movement on the pause. Reflective foil attached on micro springs inside the body maintain visual attraction even at rest. Scale Boost composite-pitch holograms add layered light reflection that mimics real baitfish scales, helping you draw reaction strikes from fish holding deeper in the water column. Jet Boost technology enhances casting distance and accuracy by shifting internal weight during the cast, then rebalancing on splashdown so your retrieve maintains a natural, lifelike cadence. The World Diver 99SP Flash Boost from Shimano quickly earns go-to jerkbait status when you need depth, realism, and consistent flash to hook suspended fish.
