Key Tradeoffs
Independent reviews rate ball-speed and distance numbers as solid for the price. Spin is the comparatively weak/derived metric, but accuracy reports differ: Plugged In Golf calls it the only metric that was "significantly off" (expected at this price) while Breaking Eighty found spin "usually…

Technology
Portable Doppler radar launch monitor. Sensor is a K-Band 24 GHz Doppler radar that tracks the ball's flight after impact. Ball-flight metrics (carry/total, ball speed, launch angle/direction, apex) are radar-measured; spin and the new "ProMetrics" set (spin axis, sidespin,…
Ball Data
On-device display shows 8 data points: carry distance, total distance, swing (club head) speed, ball speed, smash factor, launch angle, launch direction, apex (max height), and spin rate. The VoiceCaddie S app adds the ProMetrics set: spin axis, sidespin, backspin, and…
Club Data
Calculated only — one club-side metric. The unit reports "Swing Speed" (club head speed), which is radar-derived. The on-device data list (manufacturer) and independent reviews (Plugged In Golf,…

Special Balls
None — marked balls NOT required. Works with any standard USGA/R&A-conforming golf ball; no marked balls, no metallic spin stickers, no proprietary balls (Plugged In Golf: gets its metrics "without the use of specially marked golf balls").
Mounting
