Key Tradeoffs
Voice Caddie applies barometric/humidity/altitude calibration to improve distance accuracy; reviewers (Practical Golf, Plugged In Golf) describe it as giving very good estimates of swing speed, ball speed, and carry distance indoors but "certainly not perfect," with the caveat that carry is…
Sensor Technology
0 cam · 1 (single 24 GHz K-Band Doppler radar) radar
Technology
Portable Doppler radar launch monitor. Senses ball (and clubhead) motion via K-Band 24 GHz Doppler radar (microwave reflection off the moving ball) and applies barometric pressure calibration to adjust for altitude/temperature/humidity. It physically measures ball speed and…
Ball Data
5 core metrics: Carry Distance, Total Distance, Ball Speed, Swing (clubhead) Speed, and Smash Factor. No launch angle, no spin, no club path/face data. Measuring range 30-320 yards. (Note: carry is interpolated from the selected club/loft, which can make wedge readings less…
Club Data
measured (swing/clubhead speed only). No club path, face angle, attack angle, or other club-delivery metrics. The only club metric is clubhead/swing speed (radar-measured); Practice Swing Mode…

Subscription
none — no subscription. All features are on-device; no recurring cost, no app, no pairing.
Special Balls
none — no marked balls, no metallic spin stickers, no proprietary balls required. Rain or Shine Golf explicitly lists "No Special Marking Required." Standard golf balls recommended; foam/limited-flight balls will register but read short,…
Mounting
Portable / ground-level placement behind the ball (no tripod, no overhead/ceiling mount). Sits on the floor or a low surface on the same level as the ball, on the target line. Indoor and outdoor capable. · Place the unit on the ground/at ball level roughly 4-5 ft directly BEHIND the ball, aligned…
