The Stan Outdoors SX4 Thumb Release is built for archers who want fast, repeatable performance when every shot matters. Engineered to close the gap between intention and execution, its spring-assisted hook helps minimize the effect of micro-movements, so the release feels smooth, controlled, and consistent from the first draw to the final string break. The hook biases into the same position shot after shot, giving you dependable execution under pressure. Precise tuning is simple with custom T10 Torx hardware that securely locks thumb post placement, finger position, travel, and tension adjustments without stripping. Fully adjustable ergonomics let you dial in the feel to match your shooting style, while trainer lock support and wrist strap compatibility add practical versatility for practice sessions and tournament use. The compact small size and black aluminum construction deliver a secure feel in hand with a clean, performance-focused design. Made in the USA, the SX4 is designed for archers who value consistency, speed, and refined control in a thumb release that performs as hard as they do. Stan Outdoors SX4 Thumb Black (Small) 8495
