Does the SC300i work without a smartphone?

Yes, the SC300i can be used completely standalone thanks to its built-in LCD screen. After each shot, it instantly displays the essential data: carry distance, total distance, swing speed, ball speed, smash factor, launch angle, and apex. The MySwingCaddie mobile app is entirely optional. To access spin rate and detailed club statistics, the app is required.

What data does the SC300i measure?

The SC300i measures a total of 8 parameters. On the built-in screen (without a smartphone): Carry Distance, Total Distance, Club Speed, Ball Speed, Smash Factor, Launch Angle, Apex. Via the MySwingCaddie app (iOS / Android, free): Spin Rate.

Can the SC300i be used both indoors and outdoors?

Yes. The Doppler radar technology works independently of ambient lighting conditions. Outdoors: place the device approximately 1.5 m (5 ft) behind the ball, aligned with the target line. Indoors: use the same position behind the ball, whether hitting from a mat or into a practice net.

How accurate is the SC300i?

The SC300i delivers accuracy of ±3% for ball speed and up to ±3 yards for carry distance in target mode. In practice mode, carry distance accuracy is ±5%. Automatic calibration through atmospheric pressure sensors ensures reliable measurements in all conditions.

Which phones are compatible with the SC300i?

The SC300i is compatible with all iOS and Android smartphones and tablets via Bluetooth. The MySwingCaddie app is available as a free download on the App Store and Google Play.

Does the SC300i measure ball spin?

Yes, spin rate is available through the MySwingCaddie app (iOS and Android). This data is particularly useful for analyzing ball flight characteristics and optimizing trajectory depending on the club used.

What is the difference between the SC300i and the SC4 Pro?

The SC300i and SC4 Pro share the same Doppler radar technology, a built-in display, and standalone operation without a smartphone. Number of data parameters: 8 for the SC300i (including spin rate via the app) versus 13 for the SC4 Pro, which additionally provides spin axis, back spin, side spin, and dispersion. Simulator features: the SC4 Pro is compatible with E6 Connect (including 5 courses), while the SC300i does not offer golf simulation. App: the SC300i uses MySwingCaddie, while the SC4 Pro uses the Voice Caddie S app. The SC300i is the ideal choice for golfers seeking essential data at a more affordable price point.

Is a subscription required to use the SC300i?

No. The MySwingCaddie app (iOS & Android) is completely free, with no subscription or in-app purchases required. All data, statistics, and session history are freely accessible after download. There are no recurring costs after purchase.

Does the SC300i work with standard golf balls?

Yes, no special balls are required. The SC300i's Doppler radar measures the flight of any standard golf ball, whether practice or premium game balls. Unlike some competing launch monitors that require expensive specially marked balls, the SC300i is compatible with all your regular golf balls.

How can I get the best measurements with the SC300i?

For optimal results: place the SC300i approximately 1.5 m (5 ft) behind the ball aligned with the target line, make sure the device is centered directly behind the ball and square to the target line, allow at least 2 to 3 m (6 to 10 ft) between the ball and the net or screen indoors, and avoid metallic surfaces that could create interference. The built-in atmospheric pressure sensors calibrate automatically.
