Why This Monitor
Pro-grade, piece by piece
Effortless Clip-On Setup

No complex ceiling modifications, no drilling into joists. The overhead mount clips on securely and holds the unit steady session after session. You'll go from unboxing to hitting in minutes.
Accurate, AI-Driven Performance
Equipped with a high-performance processing chip and proprietary AI algorithms, the GR2 ensures precise shot data across various shot types — including accurate readings for all golf balls, even pure white ones.
The intelligent sensing system adapts to your unique swing characteristics in real time, delivering consistent, reliable data whether you're powering drives or working on wedge control.
Comprehensive Data Capture — 32 Metrics
Mounted in a front-facing overhead position, the GR2 collects 9 club data metrics and 19 ball data points for each shot — providing valuable insights to elevate your training and performance.
Club speed, smash factor, attack angle, club path, face angle, dynamic loft, ball speed, launch angle, spin rate, spin axis, carry distance, total distance, apex height, hang time, landing angle, and more — all in real time.
Innovative Smart Putting System
The smart putting system activates automatically when you're within 4 yards of the green. Experience over 200+ short putt scenarios with 3 cup groups and 11 power devices that simulate realistic green conditions.
Practice lag putts, breaking putts, and pressure putts without any manual mode switching — the GR2 intelligently detects when you've switched to your putter and adjusts automatically.
Wide Detection Range
A large sensing area eliminates the need for manual ball repositioning between shots, enhancing the practice experience and keeping your flow uninterrupted.
Hit from a natural stance without worrying about precise ball placement. The GR2's expansive detection zone accommodates the full range of club types and shot shapes.
Clear Clubhead Playback
Get vivid, detailed playback of clubhead position and ball contact for precise analysis of alignment, clubface control, ball spin, and launch angle — boosting your technique with every swing.
The high-definition slow-motion replay gives you a visual understanding of your strike pattern that numbers alone can't convey.
