The "Flash Boost" technology from Shimano is used in Bettyu Hiramasa lures. The lure's body construction has a mirrored insert that vibrates to offer constant internal reflection of light and UV. A counter-weighted spring system that ensures the vibration is maintained even when the lure is stopped amplifies this and makes it more appealing to fish even between movements. A lifelike holographic pattern that mimics the brightness of scales on the side of a bait fish is provided by the integration of Shimano's renowned "Scale Boost" finish. The Bettyu Hiramasa has a mid-tune and an unique centre of gravity, sitting erect in the water when halted to lessen the likelihood of entanglement and diving errors. An appealing sliding movement results from the increased stability, where the lure finishes resting side-on between jerks, making it perfect for anglers of all skill levels.
