What is the Voice Caddie SC4 Pro?

The Voice Caddie SC4 Pro is a portable Doppler radar launch monitor measuring 13 shot parameters (carry, ball speed, swing speed, smash factor, launch angle, apex, spin rate, spin axis, back spin, side spin, dispersion, total distance, launch direction). It works indoors and outdoors, is compatible with E6 Connect (5 courses included without subscription) and requires no subscription for the VoiceCaddie S app.

Does the SC4 Pro work indoors and outdoors?

Yes. The Doppler radar technology works independently of ambient light. Outdoors, place the device approximately 1.5m behind the ball in line with the target, with the red marker aligned with the ball. Indoors, allow approximately 3m between the ball and the net or impact screen.

How do I set up the SC4 Pro correctly?

Place the unit at hitting surface level, approximately 1.5m behind the ball, in line with the target. The ball must be aligned with the red marker on top of the device. If hitting into a net or screen, allow approximately 3m between the ball and the net/screen. Then download the VoiceCaddie S app (iOS/Android) and pair the device via Bluetooth to access all 13 parameters.

Which simulator is the SC4 Pro compatible with?

The SC4 Pro is compatible with E6 Connect and Optishot Orion. The purchase includes 5 E6 Connect courses without subscription: Aviara Golf Club & Resort, Bandon Dunes, Stone Canyon Club, Sanctuary and Wade Hampton Golf Club. A paid E6 subscription gives access to over 100 additional courses — this cost is linked to E6, not Voice Caddie.

What parameters does the SC4 Pro measure?

The SC4 Pro measures 13 parameters. In standalone mode (without smartphone): carry distance, total distance, launch direction, swing speed, ball speed, smash factor, launch angle, apex and spin rate. By connecting the VoiceCaddie S app, 4 additional parameters are available: spin axis, back spin, side spin and dispersion.

Does the SC4 Pro work with all types of golf balls?

No. The SC4 Pro requires standard golf balls conforming to R&A / USGA rules. Foam practice balls or non-standard lightweight balls may affect measurement accuracy.

What is the battery life of the SC4 Pro?

The SC4 Pro offers approximately 10 hours of battery life in continuous use. Charging is via USB-C (cable included). Battery level is visible on the device screen and in the VoiceCaddie S app.

How do I update the SC4 Pro?

Updates are free. They are performed via the VoiceCaddie S mobile app (iOS/Android) or via the VC Manager software on PC or Mac. Regular updates may extend features and simulator compatibility.

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

The SC4 Pro and SC300i both feature a built-in screen, a magnetic remote control, and smartphone-free use. The main difference lies in the number of parameters analyzed: 13 vs 8. The SC4 Pro adds spin axis, back spin, side spin, and dispersion, which are absent from the SC300i. It is also compatible with the E6 Connect simulator (5 courses included), which the SC300i does not offer. The SC300i remains an excellent choice for essential data at a more accessible price.

Is a subscription required to use the SC4 Pro?

No. The VoiceCaddie S app and firmware updates are completely free. The 5 included E6 Connect courses are accessible without subscription. Only an optional E6 subscription is needed to access additional courses — this cost is linked to the E6 software, not Voice Caddie.
