By integrating Shimano’s market leading Flash Boost technology, the Sephia Flash Boost Egi range features an internal panel which shimmers continuously. This patented system uses a reflective mirror suspended by micro springs, which harnesses light and UV rays to attract squid throughout the water column. The continuous movement of the mirror within the body is produced by kinetic energy which is highly effective to these visual hunters when the jig is paused, as this is when the squid is most likely to strike. Available in three sizes - 2.5, 3.0, and 3.5 .
