Shimano Exsence Silent Assassin 99SP not to be confused with the Shallow Assassin is the most technologically advanced bass lure Shimano has ever produced. Available in suspending and Floating versions, it is equipped with Flash Boost, Jet Boost and Scale Boost. The Excence Silent Assassin 99SP will certainly be the most appreciated lure by the most hardened gleaners. Length 99 mm. features Jet Boost for increased casting performance, perfect when fish are hunting from a distance. Flash Boost increases attraction by reflecting light, even when stationary and the Scale Boost stimulates predators to attack a bait very similar to forage fish. Using steady and smooth recovery, the Silent Assassin 90SP Flash Boost has a tight rolling action, but can be jerked, twitched for even more captivating. It's great for slower fetches just below the surface and the sinking version is the lure to turn to when fish are lower in the water column. Sinking: 0.80-1.40m.
