Benefit: flexible setup for different bow setups and flight characteristics, from standard target arrows to hunting arrows. Angles - Rotary knob enables precise 90° or 120° helical configurations, improving arrow spin and flight. Benefit: consistent fletching alignment and repeatable performance that helps with accuracy and stability. Strong Magnetic Clamp - Securely holds fletching for mess-free, easy DIY arrow building. Benefit: clean work surface, faster setup, and reduced risk of misalignment during application. Use scenarios - At home or on the range: replace worn fletching or experiment with different fletching configurations. With 2, 3, or 4 vane options and 90° or 120° helicals, you can tailor arrows for practice or hunting needs. - During a practice session or competition: quickly switch configurations to test performance with different spins and stabilization. The magnetic clamp keeps fletching in place for precise, repeatable application. - In a workshop or field repair: assemble new arrows from mixed components and perform quick DIY repairs. The universal compatibility and secure clamp streamline the process, reducing setup time and waste.
