Full Review
The Voice Caddie SC4 is radar-based, which sets it apart from the photometric monitors like the Garmin R10 at a similar price. Radar technology works well indoors without needing strong lighting. The SC4 has a built-in screen showing your shot data immediately after each swing, so you do not need to look at your phone. It measures 8 data points and supports E6 Connect for simulator play. The accuracy is solid for a radar unit at this price. The SC4 is a good choice for golfers who want a monitor that works reliably indoors without fussing with camera placement and lighting.

Who Is This For?
The SC4 is the radar alternative at the budget price point. Choose it over the Garmin R10 if you are setting up an indoor bay where lighting control is difficult, or if you simply prefer not having to check your phone after every shot.
