Who each one is better for
Honest persona fit, side by side.
Better for MLM2XPRO
- Family Setup
It sits behind the ball, so left- and right-handed players share it without moving anything; handedness is a setting in the app. Rapsodo says Core adds a second golfer profile and Studios three more.
Both fit
- Recreational Player
- Cost-Effective Buyer
