The fine print
Spin is radar/algorithm-derived, not optically measured; accuracy typically several hundred RPM variable. No club path/face angle despite some marketing claims. VoiceCaddie S app is free with all core metrics and 3D range. E6 Connect optional: 5 courses free, additional courses require subscription (price not published).

Specifications

Core Technology
Core Tech TypeRadar
Sensor Technologyno cameras, 1 radar
Technology DetailPortable Doppler radar launch monitor. Sensor is a K-Band 24 GHz Doppler radar that tracks the ball's flight after impact.
Performance Data
Ball DataOn-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.
Club DataCalculated only, one club-side metric. The unit reports "Swing Speed" (club head speed), which is radar-derived.
Compatibility
Sim Readiness and Software IncludedE6 Connect (iOS and PC) and OptiShot Orion, plus the bundled VoiceCaddie S app (native 3D driving range, target mode, practice mode, swing-speed mode).
Device / PC ReqsBoth. Runs standalone on its own onboard display; pairs to a MOBILE app (Voice Caddie S / MySwingCaddie) and is also compatible with PC/Mac simulator software (E6 Connect / OptiShot Orion).
Subscription CostNo subscription required for core use, the VoiceCaddie S app (data storage, spin/ProMetrics metrics, 3D range) is free on iOS/Android.
Special Balls/MarkersNone, 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").
