TRAINING & FITTING MODES
SWING & SHOT ANALYSIS
Enhance your practice by choosing specific data points
APPROACH ANALYSIS
Set target distance to practice specific shots (up to 219 yards) & change pin positions
PUTTING ANALYSIS
Practice putting distances ranging from 3 ft to 120 ft
ON-COURSE PRACTICE
Play simulated courses with tour-level realism. Adjust distances, pins, and conditions to practice like a pro.
CUSTOMIZED PRACTICE
Create any shot scenario. Adjust ball position, pin location, and conditions to replicate practice rounds that the pros play.
CLUB FITTING MODE
Fitters can compare up to 15 club groups, capture up to 100 shots per group, and generate instant fitting reports. Analyze trajectories, dispersion, impact, and stroke patterns — including putting.
