Callaway Chrome Soft X RPT is a tour-grade golf ball with a unique printed pattern that allows Rapsodo MLM2 PRO to measure spin speed and spin axis with high precision. The ball has the same construction as the standard Chrome Soft X, including a urethane cover and a firm core, but is equipped with the RPT pattern to allow precise tracking of the ball’s rotation when used with the MLM2 PRO Impact Vision camera. This makes the ball particularly useful for indoor practice and simulator use where accurate measurement of the ball’s spin is important.
