Shimano's Ocea Bomb Dip 170F Flash Boost is designed for aggressive surface-feeding predators. Powerful popper designed for inshore and offshore fishing. It features the exclusive JET BOOST and FLASH BOOST technologies to increase performance. When aggressive fish like tuna and GT are feeding close to the surface, few lures beat a popper for action and the Ocea Bomb Dip 170F is no exception. From the very first cast you will notice how the Jet Boost technology propels the lure through the air, reaching distances you thought unreachable - useful when tuna are schooling away from your boat. And when retrieved, the 'pop' is strong and aggressive and draws fish in and up like few other lures. But this lure has more than just sound. Flash Boost technology creates a reflection of light within the translucent body, even when stationary, to allow predators to approach the lure with speed and aggression.
