Voice Caddie Swing Caddie SC300i Launch Monitor
The Voice Caddie Swing Caddie SC300i is a portable launch monitor that delivers a complete analysis of your swing, ball flight, carry and total distance, launch angle, and apex data — all in one compact, field-ready device. Building on the award-winning SC300 platform, the SC300i adds improved atmospheric pressure sensors and full spin data via the MySwingCaddie V2 app, bringing professional-grade performance metrics to golfers of every level. Connect wirelessly via Bluetooth to your smartphone, tablet, or computer to track every shot in real time, or use the unit as a standalone device without any app at all. State-of-the-art Doppler radar technology ensures uncompromising accuracy, and the device can be placed just 1.5 m (approximately 60 inches) directly behind the ball — no complicated setup required.

Technology in Detail
Doppler Radar Technology
The SC300i uses K-band 24 GHz Doppler radar — the same fundamental technology found in high-end professional launch monitors — to measure every relevant parameter of ball flight and clubhead motion. The radar tracks the ball from the moment it leaves the face through the full trajectory, calculating ball speed, launch angle, carry distance, total distance, swing speed, and smash factor with exceptional fidelity. Accuracy is rated at ±2% for ball speed, ±3 yards for carry distance in target mode, and ±3% for carry distance in practice mode. Improved atmospheric pressure sensors compared to the original SC300 further refine readings under varying weather conditions, making this one of the most reliable portable monitors in its class.
Spin Data via MySwingCaddie V2 App
Spin rate is one of the most critical data points for understanding how your ball behaves in the air, and the SC300i now delivers full spin data when paired with the MySwingCaddie V2 app. By combining radar readings with the app's processing algorithms, the SC300i calculates the rate and direction of ball rotation — information that helps you dial in optimal launch conditions for every club. This data is displayed in real time on your phone or tablet alongside all other shot metrics, giving you a complete performance picture that was previously only accessible with professional-grade studio equipment.
MySwingCaddie V2 App — Record, Review & Analyse
The free MySwingCaddie V2 app for iOS and Android transforms the SC300i into a full practice studio. Beyond displaying live shot data, the app includes a video analysis feature that lets you record your swing and overlay the corresponding shot statistics directly onto the footage — ideal for identifying swing faults and tracking improvement over time. All shot data is stored per club, so you can build detailed performance profiles for every iron, wood, and wedge in your bag. Statistics and trends are easy to review between sessions, helping you make smarter decisions on the course and on the range.
Voice Readout & Remote Control
After each shot, the SC300i announces your carry distance aloud via its built-in speaker, so you never need to walk back to the device to check your results — ideal for range sessions and on-course play. The included wireless remote control lets you start and stop measurements, change clubs, and navigate the on-device menu from a distance. Together, these features make the SC300i one of the most practical and user-friendly portable launch monitors available, eliminating interruptions to your practice routine and keeping you fully focused on your game.
5.3" LCD Display & Standalone Operation
The large 5.3" LCD display shows all key shot data instantly after each strike — no app or phone connection required. This makes the SC300i fully self-contained: simply place it 1.5 m behind your ball, switch it on, and start practising. Adjustable loft settings allow you to configure the device for every club in your bag, ensuring that carry and total distance calculations are correctly calibrated for each shot. With up to 20 hours of battery life from its lithium-polymer cell and convenient USB-C charging, the SC300i is ready for a full day of range work on a single charge.
