Bettyu Hiramasa lures feature Shimano’s 'FLASH BOOST' technology. A mirrored insert is housed within the lure’s body structure, vibrating to provide a continuous internal reflection of light and UV. This is amplified by a counter weighted spring mechanism that ensures the vibration is maintained even when the lure is paused, continuing to invite fish between movements. Shimano’s signature ‘SCALE BOOST' finish is integrated providing a life-like holographic pattern to emulate the brilliance of scales on the side of a bait fish. The Bettyu Hiramasa features a mid-tune and is designed with a specific centre of gravity, sitting in the water in an upright posture when paused to reduce the chance of entanglement and diving mistakes. The improved stability creates an attractive sliding action where the lure finishes resting side-on between jerks, making it perfect for anglers of all skill levels.
