GolfJoy GR3 Pro Overhead Launch Monitor
GolfJoy GR3 Pro Overhead Launch Monitor
Next-Generation Overhead Tracking
GolfJoy GR3 Pro Overhead Launch Monitor
The GolfJoy GR3 Pro is GolfJoy’s most advanced overhead launch monitor, combining triple-camera precision, enhanced AI processing and an expanded detection area to deliver exceptionally fast and detailed feedback from full swings through putting.
Advanced Golf Data Without a Floor-Mounted Device
Mounted above and in front of the hitting area, the GR3 Pro keeps the floor clear while allowing golfers to address the ball naturally. Its three high-speed cameras, dual LED lighting systems and upgraded processing hardware capture detailed ball, club and trajectory information in milliseconds.
The overhead configuration makes the GR3 Pro an excellent choice for premium home simulators, teaching studios, club-fitting environments and commercial golf facilities. Built-in positioning sensors also help accommodate spaces used by both right- and left-handed golfers.
Triple-Camera Precision
Three high-speed cameras capture detailed ball and club movement at impact.
Up to 42 Metrics
Comprehensive ball, club and calculated trajectory information for every shot.
Near-Instant Feedback
Calculation time and detection latency are rated at 0.2 seconds or less.
Clear Clubhead Playback
Review club position and ball contact for more informed swing adjustments.
Built for Speed, Accuracy and Natural Play
AI-Powered Shot Analysis
An upgraded processing chip works with GolfJoy’s advanced algorithms to analyze different shot shapes, trajectories and impact conditions. The system supports normal golf balls—including solid white balls—without requiring specialty marked balls.
Triple High-Speed Cameras
Three cameras and two LED lighting arrays capture high-definition impact information in milliseconds. This optical system helps the GR3 Pro measure ball movement and club delivery while providing clear visual feedback of the strike.
Expanded Hitting Area
The GR3 Pro provides a 60 × 60 cm detection zone, allowing golfers to position the ball naturally without repeatedly moving it into a small designated location.
Right- and Left-Handed Adaptability
Built-in GPS and gyroscope technology assist with monitor alignment and positioning. This is particularly useful in shared simulator rooms where right- and left-handed golfers need sufficient swing space.
Broad Shot Compatibility
The GR3 Pro is designed to capture full swings, high-lofted shots, chip-and-runs, delicate short-game shots and putts for a more complete simulator and practice experience.
Up to 42 Golf Data Parameters
Analyze ball flight, club delivery and calculated trajectory information for practice, coaching, fitting and simulator play.
