Stop missing shots because your launch monitor can't see the ball. LiteMark reflective dot stickers give your Foresight GCQuad, GC3, GC2, or HMT camera the precise optical reference points it needs to track every shot accurately. PRECISION-ENGINEERED FOR PHOTOMETRIC SYSTEMS: Each dot is precision-cut to the exact 4.2mm diameter specified by Foresight Sports for reliable ball and club face detection. Works with GCQuad, GC3, GC2, HMT, and other high-speed photometric launch monitors. PREMIUM 3M RETROREFLECTIVE FILM: Built with high-grade 3M retroreflective material for consistent, high-contrast visibility in any lighting condition - bright outdoor sun or dim indoor simulator rooms. WEATHERPROOF & LONG-LASTING: UV-stable, weatherproof adhesive bonds securely to smooth plastic, rubber, and metal surfaces and lasts up to 7 years without peeling, lifting, or losing reflectivity. APPLICATION: Works best on smooth, clean, dry surfaces. Peel the dot from its backing and firmly press onto the desired location on the ball or club face. Smooth out any air bubbles from the center outward. Apply 2-3 dots to the golf ball in a triangular pattern around the equator, and 2-3 dots centered on the club face. Compatible with Foresight Sports GCQuad, GC3, GC2, HMT, and other photometric camera-based launch monitors. Made in the USA.
