Head-to-head
Garmin R50 vs Voice Caddie SC4 Pro: R50 can solve rear sensor clearance without fixing an unsafe swing space
The short answer
Mark the hitting position, rear wall and net stand-off separately. A camera beside the ball can solve a rear-clearance problem, but it cannot fix an unsafe swing arc or an impact screen installed too close to a wall.
Before you choose
The reasoning and the trade-offs
A 14ft sensor-to-net envelope misses the SC4 Pro recommendation
SC4 Pro calls for 5ft behind the ball and recommends 10ft to the net, totaling 15ft. R50 sits beside the ball and avoids that rear-radar requirement.
What this is based on
5 + 10 = 15ft. A 14ft available sensor-to-net length is 1ft short. No minimum complete R50 room depth is inferred.
Main trade-off
Voice Caddie SC4 Pro
E6 compatibility is not available on Android according to Voice Caddie's comparison page.

Both provide an on-unit display, so the required companion-display count for basic practice is zero on each. Their screens serve different jobs.

What matters in practice
The differences that matter
A 14ft sensor-to-net envelope misses the SC4 Pro recommendation
SC4 Pro calls for 5ft behind the ball and recommends 10ft to the net, totaling 15ft. R50 sits beside the ball and avoids that rear-radar requirement.
How we reached this conclusion
5 + 10 = 15ft. A 14ft available sensor-to-net length is 1ft short. No minimum complete R50 room depth is inferred.
A five-hour range visit exceeds the R50 battery rating
SC4 Pro is rated around 10 hours, leaving 5 hours against a five-hour plan. R50 is rated up to 4 hours and needs another power arrangement.
How we reached this conclusion
10 minus 5 = 5 hours of nominal reserve. 4 minus 5 = negative 1 hour. These are rated-runtime comparisons rather than field tests.
Neither needs a phone just to show native practice numbers
Both provide an on-unit display, so the required companion-display count for basic practice is zero on each. Their screens serve different jobs.
How we reached this conclusion
R50 integrated touchscreen = 0 required companion displays. SC4 Pro numeric display = 0. Course software and projection have additional requirements.

Meaningful differences
What changes the fit
| What changes | Garmin Approach R50 | Voice Caddie SC4 Pro | Why it matters |
|---|---|---|---|
| Placement | Beside the ball, approximately 1.5ft from the tee location | 5ft behind the ball with a recommended 10ft to the net | Measure the usable rear and front distances separately. Beside-ball cameras still need safe swing and impact clearance. |
| Viewing results | Built-in 10-inch touchscreen with impact video | Built-in numeric screen and remote control | A built-in numeric screen, a full touchscreen and a companion app create different practice routines. |
| Power arrangement | Rechargeable battery rated up to 4 hours | Rechargeable battery rated about 10 hours | Include the phone or computer and any continuous power cables when planning a complete session. |
| Ball and club preparation | Standard golf balls. Tracking stickers required for specified club metrics | Standard golf balls. Non-standard practice balls are excluded | Supported markings and stickers are measurement requirements. They are not interchangeable across 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 | Check the exact included license, compatible device and paid features before comparing total setup costs. |
| Practice location | Indoor and outdoor use | Indoor and outdoor use | An indoor-only restriction remains a hard limit even if the hardware is small enough to carry. |
What you give up
Every choice has a cost
If you choose Garmin Approach R50
- Club measurements need the supplied tracking stickers, and the side-mounted unit must move when right- and left-handed golfers alternate.
If you choose Voice Caddie SC4 Pro
- The radar still needs rear placement and enough ball flight indoors.
Recommendation switch
The decision flips if...
You lack room behind the hitting spot
Choose Garmin Approach R50. Mark the hitting position, rear wall and net stand-off separately. A camera beside the ball can solve a rear-clearance problem, but it cannot fix an unsafe swing arc or an impact screen installed too close to a wall.
You want standalone numeric feedback at the range
Choose Voice Caddie SC4 Pro. SC4 Pro is easier to treat as a numeric practice appliance during a long range day. R50 adds visual impact feedback and a richer built-in screen, which may be worth carrying a charger for.

Neither needs a phone just to show native practice numbers
Choose R50 for visual shot review and on-device Garmin simulation with the required membership. Choose SC4 Pro when a numeric screen, remote and compatible E6 path cover the plan. A shared standalone label does not make their simulator interfaces equivalent.
What this comparison cannot tell you
- Room calculations describe sensor geometry. They do not certify a safe room width, ceiling height or net installation.
- Battery calculations use manufacturer upper ratings and exclude the companion display.
- No side-by-side accuracy, shot-tracking reliability or simulator latency test is claimed.
