How is spin rate and spin axis measured?

Through our partnership with Callaway, we are using specially engineered balls using Callaway’s Truvis Technology and Rapsodo patented RPT (Rapsodo Precision Technology) pattern where we can measure spin and spin axis hyper accurately.

Does the MLM2PRO support other types of balls to measure spin (IE RCT or metallic dot?)

No, the Callaway x Rapsodo RPT balls are the only balls that can be used to measure spin and spin axis on. the MLM2PRO.

Will I get spin rate and spin axis if I use a regular golf ball instead of the Callaway RPT balls?

Currently, we are not showing spin numbers without the RPT Ball. If estimating spin meets our accuracy thresholds, it can be a potential release in the future.

Do I have to use the Callaway x Rapsodo RPT balls in order to get data?

You do not need to use the RPT balls in order to get data on the MLM2PRO. The RPT balls are needed in order to get any spin data on the MLM2PRO.

Where can I purchase more golf balls?

Additional golf balls can be purchased on the Rapsodo website for $ dozen.
