The catch
Garmin Approach R50
You need an active Garmin Golf membership to play courses on Home Tee Hero.
Side by side
Measure the hitting position, the rear wall and the net stand-off one by one. A camera beside the ball can fix a shortage of rear clearance, but it does nothing for an unsafe swing arc or an impact screen hung too close to a wall.
Before you buy
For SC4 Pro, that is 5ft behind the ball plus a recommended 10ft to the net, totaling 15ft. R50 sits beside the ball and skips the rear-radar requirement.
Where this comes from
5 + 10 = 15ft, so an available sensor-to-net length of 14ft comes up 1ft short. This does not infer any minimum complete room depth for R50.

R50 and SC4 Pro differ on room layout, required devices, ball preparation and software access. Compare them before you build your practice setup.
With little room behind the hitting spot, R50 is the one to choose. For standalone numeric feedback at the range, choose SC4 Pro.
Which one fits
For SC4 Pro, that is 5ft behind the ball plus a recommended 10ft to the net, totaling 15ft. R50 sits beside the ball and skips the rear-radar requirement.
Against a five-hour plan, SC4 Pro's rating of around 10 hours leaves 5 hours. R50 is rated up to 4 hours, so it calls for another power arrangement.
Each has a display on the unit, which puts the companion-display count for basic practice at zero for both. The screens do different jobs.
R50: built-in 10-inch touchscreen with impact video. SC4 Pro: built-in numeric screen and remote control. For a phone-free setup, check the separate display requirement before you buy.
In practice

Against a five-hour plan, SC4 Pro's rating of around 10 hours leaves 5 hours. R50 is rated up to 4 hours, so it calls for another power arrangement.
10 minus 5 leaves 5 hours of nominal reserve, while 4 minus 5 = negative 1 hour. These compare rated runtimes and are not field tests.

Required companion displays: R50 integrated touchscreen = 0, SC4 Pro numeric display = 0. Course software and projection bring additional requirements of their own.

Garmin, Approach R50
Tracking comes from three high-speed cameras, and the documented use spans indoor and outdoor practice.

Voice Caddie, SC4 Pro
This Doppler-radar monitor has a built-in numeric display and handles range practice and compatible simulators. For indoor use, the recommended setup is 5 feet behind the ball and 10 feet of flight.
Spec by spec
| Spec | Garmin Approach R50 | Voice Caddie SC4 Pro | In practice |
|---|---|---|---|
| Placement | Beside the ball, approximately 1.5ft from the tee location | 5ft behind the ball with a recommended 10ft to the net | Take the usable rear distance and the front distance as separate measurements. Cameras beside the ball still need safe swing and impact clearance. |
| Viewing results | Built-in 10-inch touchscreen with impact video | Built-in numeric screen and remote control | Practice routines differ depending on whether you have a built-in numeric screen, a full touchscreen or a companion app. |
| Power arrangement | Rechargeable battery rated up to 4 hours | Rechargeable battery rated about 10 hours | When you plan a full session, count the phone or computer and any cables that must stay plugged into power. |
| Ball and club preparation | Standard golf balls. Tracking stickers required for specified club metrics | Standard golf balls. Non-standard practice balls are excluded | Markings and stickers must be the supported ones for measurement to work, and they cannot be swapped between brands. |
| Software ownership | On-device practice and Home Tee Hero. Home Tee Hero requires membership | Standalone practice, VOICECADDIE S app and compatible E6 Connect setup | Before you compare total setup costs, confirm exactly which license is included, which device works and which features are paid. |
| Practice location | Indoor and outdoor use | Indoor and outdoor use | Even when the hardware is small enough to carry, an indoor-only restriction is still a hard limit. |
Trade-offs
Change of plan
Go with Garmin Approach R50. Measure the hitting position, the rear wall and the net stand-off one by one. A camera beside the ball can fix a shortage of rear clearance, but it does nothing for an unsafe swing arc or an impact screen hung too close to a wall.
Go with Voice Caddie SC4 Pro. Over a long range day, SC4 Pro is the easier one to treat as a plain numeric practice appliance. R50 brings visual impact feedback and a richer built-in screen, and that may justify taking a charger along.
Decision guide
Treat the hitting position, rear wall and net stand-off as three separate measurements. Placing a camera beside the ball can solve a rear-clearance problem. It cannot make an unsafe swing arc safe, and it cannot help if the impact screen sits too close to a wall.
Over a long range day, SC4 Pro is the easier one to treat as a plain numeric practice appliance. R50 brings visual impact feedback and a richer built-in screen, and that may justify taking a charger along.
R50 is the choice for visual shot review and on-device Garmin simulation, which requires the membership. SC4 Pro is the choice if a numeric screen, a remote and a compatible E6 path cover what you plan to do. Both being called standalone does not make their simulator interfaces equivalent.
