The SC4 Pro is for golfers who want spin figures and a home simulator option from a compact radar unit, without needing to look at a phone between shots. What sets it apart is the combination of a built-in screen, spin rate with side spin and back spin, and access to E6 Connect simulation with a free course and driving range on iOS.

Our take
What it measures
The listing names eight key data points: carry and total distance, ball speed, swing speed, smash factor, apex, launch angle, launch direction, and spin rate with side spin and back spin. Doppler radar is the measuring technology.
Spin data matters more than most beginners realise. Too much back spin with a driver costs distance, and side spin explains a slice better than the ball flight alone.
Simulation and apps
The SC4 Pro works with E6 Connect. The free tier includes one course and a driving range, and more courses require an optional subscription. Voice Caddie stresses that simulators are only available on iOS, not Android, which is crucial for Android phone owners. The Voice Caddie S app adds range simulation and advanced metrics.
Hardware and setup
The unit weighs 590 g, comes with a remote, a USB cable and a manual, and runs on an included lithium polymer battery. The product details mention a 10 inch display, though that figure looks like a catalogue error for a unit of this size. Distances are also read out by voice, so you can practise without looking down.
Compared with the MLM2PRO and SC300i
The Rapsodo MLM2PRO uses dual cameras plus radar, measures spin, records swing video and offers simulation at over 30,000 courses. The Voice Caddie SC300i is the older radar unit from the same brand, with spin rate and apex but a simpler app. The SC4 Pro sits between them, with the screen and simulator link.
Who should look elsewhere
Android users who want simulation should look at other options, since that part of the package is iOS only. Golfers who want a full indoor simulator with photometric cameras will find the SkyTrak ST MAX more capable.
Verdict
Buy the SC4 Pro if you want spin data, a built-in screen, voice feedback and a simple path to home simulation on an iPhone or iPad. If you want swing video and a large course library, the Rapsodo MLM2PRO is the alternative, and the SC300i suits those who want a lighter radar unit.
