RPT golf balls provide a precisely measured spin rate when paired with an MLM2PRO. Rapsodo Golf is currently working with Titleist to allow RCT golf balls to also display an accurate measured spin rate when used with an MLM. This feature is still being tested, but we hope to make it available soon.
Additionally, RPT golf balls (when paired with an MLM2PRO) also provide a spin axis measurement. The spin axis metrics will not be available on MLM units on account of the device’s design. This means every shot tracked by the MLM/RCT involve estimates of the curve and overall carry/side carry, Since the RPT golf ball provides both measured spin rate and spin axis, the metrics reported are extremely accurate for carry and curve.
