The catch
Voice Caddie SC4 Pro
Voice Caddie's comparison page says E6 compatibility does not extend to Android.
Side by side
Total spans of 15ft and 16ft should not settle this on their own. Where the available space sits matters too, particularly if a garage door, pillar or storage rack pins down the hitting spot.
Before you buy
Behind the ball, SC4 Pro asks for 5ft and Mevo Gen2 specifies 8ft. In the same rear zone, SC4 has 1ft of nominal margin while Mevo is 2ft short.
Where this comes from
Say 6ft is clear behind the hitting spot. 6 minus 5 = 1ft and 6 minus 8 = negative 2ft. Front flight requirements stay at 10ft and 8ft respectively.
The catch
Voice Caddie's comparison page says E6 compatibility does not extend to Android.
The catch
Published indoor requirements total about 16 feet, before any room for the player's swing.

Room layout, required devices, ball preparation and software access are the points to weigh between SC4 Pro and Mevo Gen2, before you build your practice setup.
For standalone feedback and a remote, go with SC4 Pro. For the FS Golf analysis workflow, go with Mevo Gen2.
Which one fits
Behind the ball, SC4 Pro asks for 5ft and Mevo Gen2 specifies 8ft. In the same rear zone, SC4 has 1ft of nominal margin while Mevo is 2ft short.
For an eight-hour event, SC4 Pro’s 10-hour rating leaves 2 hours, but without charging Mevo Gen2’s 6-hour rating falls 2 hours short.
Five included E6 courses appear on the SC4 Pro page that was checked, and Mevo Gen2 lists eight. The difference is three additional included courses and says nothing about simulator quality.
SC4 Pro: built-in numeric screen and remote control. Mevo Gen2: FS Golf on a compatible phone, tablet or PC. For a phone-free setup, check the separate display requirement before you buy.
In practice
Behind the ball, SC4 Pro asks for 5ft and Mevo Gen2 specifies 8ft. In the same rear zone, SC4 has 1ft of nominal margin while Mevo is 2ft short.
Say 6ft is clear behind the hitting spot. 6 minus 5 = 1ft and 6 minus 8 = negative 2ft. Front flight requirements stay at 10ft and 8ft respectively.
For an eight-hour event, SC4 Pro’s 10-hour rating leaves 2 hours, but without charging Mevo Gen2’s 6-hour rating falls 2 hours short.
10 minus 8 = 2 hours, and 6 minus 8 = negative 2 hours. Manufacturer battery ratings do not account for real weather or the separate app device.
Five included E6 courses appear on the SC4 Pro page that was checked, and Mevo Gen2 lists eight. The difference is three additional included courses and says nothing about simulator quality.
8 minus 5 = 3 courses. The package listed by each manufacturer and reviewed for this comparison is what both counts refer to. Platform and activation requirements still apply.

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.

FlightScope, Mevo Gen2
It uses 3D radar plus image processing for tracking, and the published indoor planning depth is 16 feet.
Spec by spec
| Spec | Voice Caddie SC4 Pro | FlightScope Mevo Gen2 | In practice |
|---|---|---|---|
| Placement | 5ft behind the ball with a recommended 10ft to the net | 8ft behind the ball and 8ft limited ball flight | 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 numeric screen and remote control | FS Golf on a compatible phone, tablet or PC | 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 about 10 hours | Rechargeable battery rated up to 6 hours with USB-C | 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. Non-standard practice balls are excluded | Aluminum stickers or Titleist RCT balls for accurate limited-flight spin | Markings and stickers must be the supported ones for measurement to work, and they cannot be swapped between brands. |
| Software ownership | Standalone practice, VOICECADDIE S app and compatible E6 Connect setup | FS Golf and eight included E6 courses. Other packages have separate terms | 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 Voice Caddie SC4 Pro. Total spans of 15ft and 16ft should not settle this on their own. Where the available space sits matters too, particularly if a garage door, pillar or storage rack pins down the hitting spot.
Go with FlightScope Mevo Gen2. Over long range sessions, SC4’s built-in screen means less gear to bring and fewer things to charge. Mevo’s USB-C and app workflow can still work for the event if you plan reliable charging.
Decision guide
Their 15ft and 16ft total spans should not be the only basis for a choice. The location of the available space counts as well, especially when a garage door, pillar or storage rack fixes the hitting spot.
Over long range sessions, SC4’s built-in screen means less gear to bring and fewer things to charge. Mevo’s USB-C and app workflow can still work for the event if you plan reliable charging.
Look at the real course list and at the device you need to run it. When a course you like falls outside the included selection, its extra license may matter more than the headline count.
