Our view
The Voice Caddie SC4 Pro makes a strong argument at around £480. It is one of the only launch monitors at this price with all three of: a built-in screen, spin metrics, and E6 simulator compatibility. Most devices at this price point compromise on at least one of those three things.
The built-in screen is the most practically useful feature for golfers who want data without the friction of phone pairing. Carry distance, ball speed, smash factor, launch angle, and spin rate are all displayed immediately after each shot. The magnetic remote control means you can select clubs and adjust settings from the hitting area without walking back to the device. Voice output calls out your distance after each shot — useful for range sessions where you want to stay in your routine.
The ProMetrics engine adds spin axis, side spin, backspin, and dispersion when connected to the VoiceCaddie S app. These are meaningful additions — spin data at this price point is unusual and gives golfers insight into shot shape and curvature that most budget devices cannot provide.
The E6 integration is a genuine bonus. Five courses are included free with no ongoing subscription required for basic use — if you just want to play virtual golf on those five courses, you can do so from day one at no extra cost. Additional courses are available via E6 subscription if you want more.
The honest limitations are the app. Earlier Voice Caddie app versions received criticism for usability. The VoiceCaddie S app is an improvement, though Android support was still in development at time of writing — check current compatibility before purchasing if you are an Android user. When connected to the app, the built-in screen switches to SIM mode and shows no individual shot data — a quirk worth knowing about.
Independent reviews note that when the device is connected to the app you lose the built-in screen data, which feels like a design compromise. The indoor accuracy is solid for the price provided setup guidelines are followed carefully.

The combination of built-in screen, spin data, and free E6 courses makes it the most complete entry-level package available. iPhone users will get the best experience — Android users should check app compatibility before purchasing.
