The heavy-duty design and construction of the Light Stryke 2.0 is made to endure the abuse of those that demand it. The Light Stryke takes the guess work out of bowfishing and features heavy-duty T-6 aluminum construction, toolless windage and elevation adjustment, and precision windage micro-adjust. Uses a Sealed pressure switch connection and powerful 5mW green laser. Compact design fits all recurve and compound bows with sight bushings. Includes pressure switch and constant on/off end cap. Approximate burn time with constant on/off switch is 6 hours.
