Key Tradeoffs
Manufacturer-published accuracy: +/-2% ball speed; +/-3 yards carry distance in Target mode; +/-3% carry distance in Practice mode. Measuring range 10 yds ~ 370 yds. Spin is an algorithmic estimate, not measured (lower confidence metric). Independent testing (PluggedInGolf vs Foresight GC2):…

Radar
Sensor Technology
0 (no cameras — radar-based) cam · 1 (single K-Band 24 GHz Doppler radar) radar
Technology
Portable doppler radar launch monitor. Senses ball motion via a single K-Band 24 GHz Doppler radar sensor placed on the ground ~5 ft behind the hitter, in line with the target. It combines radar data with a calibrated atmospheric (barometric) pressure sensor to correct distances
Ball Data
~7-8 metrics. On-device LCD: Carry distance, Total distance, Ball Speed, Swing (club head) Speed, Smash Factor, Launch Angle, Apex (max height). Via MySwingCaddie app only: Spin Rate (driver through 8-iron). Display modes include Target, Practice, and Approach/short-game modes.…
Club Data
Measured/derived: swing speed (club head speed) and smash factor from the radar. No club path, face angle, attack angle, or other club-face delivery metrics — those are not provided.
Sim Ready
Not a simulator unit. The SC300i is a range/practice launch monitor and does NOT natively drive simulator software (GSPro, E6, TGC/2K, FSX, Awesome Golf). Voice Caddie's simulator-capable product is the separate SC4 PRO (E6 Connect support)
