Yes. R-Motion will work with Almost golf balls. In the settings menu, please select "ALMOST GOLF BALL" option, when using ALMOST golf balls. Otherwise, keep the setting to default value of "REGULATION BALL".
Regular foam balls are discouraged from being used, as their use would lead to somewhat inaccurate results.
However, we encourage the use of regulation hard balls for use with R-MOTION as they will produce the most accurate results.
