Side by side
Voice Caddie SC4 Pro vs Square Golf Square Home Compared: Rear space is freed up by Square, but it cannot double as an outdoor range monitor
Quick verdict
When the rear wall is what limits you, Square deserves a look. It does not suit you if the same purchase has to work at an outdoor driving range, even when a covered range resembles an indoor bay.
Before you buy
Why, and what it costs you
A 13ft sensor-to-net span falls 2ft short of the SC4 Pro recommendation
A combined layout of 15ft is what SC4 Pro recommends. Square Home needs no radar unit behind the golfer, though its indoor mat and net still need safe spacing.
Where this comes from
5ft rear + 10ft front = 15ft, and 13 minus 15 = negative 2ft. Square is not given any full-room minimum.
The catch
Square Golf Home Launch Monitor
Outdoor sunlight is outside what the Home model is meant for.

How we worked this out

Added up, the sessions come to 7.5 hours. That leaves 2.5 hours on SC4 Pro’s 10-hour rating and half an hour on Square’s 8-hour rating.
How we worked this out
5 × 1.5 = 7.5 hours. Then 10 minus 7.5 = 2.5 and 8 minus 7.5 = 0.5. The reserves assume continuous rated use and no charging.

Say two opposite-handed players alternate for 20 turns. A beside-ball Square has to switch sides at every handover, while a rear-positioned SC4 Pro can stay behind the common tee line.
How we worked this out
With twenty alternating turns, 20 minus 1 = 19 handovers. The scenario assumes a shared hitting spot and enough swing clearance for both players.

- Which simulators work depends on the supported platform and the current software plan.
Option B
Square Golf, Square Golf Home

Spec by spec
Where they really differ
| Spec | Voice Caddie SC4 Pro | Square Golf Home Launch Monitor | In practice |
|---|---|---|---|
| Placement | 5ft behind the ball with a recommended 10ft to the net | Camera beside the ball, indoors and away from direct sunlight | 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 | Bluetooth-connected phone, tablet, laptop 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 | Removable lithium-ion battery rated up to 8 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. Non-standard practice balls are excluded | Supported marked balls. Supplied dotted balls and original TaylorMade TP5 Pix markings are documented | 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 | Square practice and pay-per-hole course credits. Check separate connector 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 only | Even when the hardware is small enough to carry, an indoor-only restriction is still a hard limit. |
Trade-offs
What each pick costs you
With Voice Caddie SC4 Pro
- Indoors, the radar still sits behind the ball and needs enough flight distance.
With Square Golf Home Launch Monitor
- Because it mounts at the side, it has to be moved to switch between right- and left-handers.
Change of plan
When the answer changes
Your practice happens outside as well as inside
Go with Voice Caddie SC4 Pro. When the rear wall is what limits you, Square deserves a look. It does not suit you if the same purchase has to work at an outdoor driving range, even when a covered range resembles an indoor bay.
Rear radar will not fit in your short indoor bay
Go with Square Golf Home Launch Monitor. A removable battery helps Square in a fixed indoor routine, yet the screen it connects to runs on its own power. SC4 Pro’s numeric screen is built in, so basic practice carries no such extra dependency.
Decision guide
How to decide
A 13ft sensor-to-net span falls 2ft short of the SC4 Pro recommendation
Square deserves consideration if the rear wall is your limit. It is the wrong buy when one purchase must also work at an outdoor driving range, even if a covered range looks much like an indoor bay.
Both published battery ratings cover five 90-minute sessions
A removable battery helps Square in a fixed indoor routine, yet the screen it connects to runs on its own power. SC4 Pro’s numeric screen is built in, so basic practice carries no such extra dependency.
A side camera can mean 19 sensor moves when handedness alternates
Rear radar is handy for group practice, provided the room fits. Square can still serve both golfers, and batching each player’s shots together cuts the number of moves and repeat alignment checks.
What this page can’t tell you
- The room figures reflect sensor geometry. They do not certify a safe room width, ceiling height or net installation.
- Manufacturer upper ratings drive the battery calculations, and the companion display is left out.
- No side-by-side test of accuracy, shot-tracking reliability or simulator latency is claimed anywhere here.
