Square Golf Launch Monitor (UK, 2026): The £700 Camera Unit, Honestly Assessed

HomeSimGolf rating: 4.2 out of 5

The Square Golf launch monitor costs around £700 in the UK and is the only camera-based unit anywhere near that price. That single fact explains the attention it’s getting: camera systems sit beside the ball rather than behind it, which makes them the right architecture for small UK garages and garden rooms, and until Square arrived the cheapest credible camera option cost more than double. Published testing and community reports rate its ball data as remarkably close to premium units, with a known weakness in side-to-side dispersion, particularly with the driver.

Here’s what it is, where it genuinely competes, and who should pick it over the Garmin R10 or Rapsodo MLM2PRO.

What the Square Golf actually is

A compact camera-based (photometric) launch monitor, roughly 19cm long and 7cm square, that sits to the side of the ball and reads club and ball at impact. It runs about 8 hours on a charge, tracks a hitting zone of roughly 15cm square, and connects to your own simulator software or its built-in courses. It ships with marked balls, which matter more than they sound, covered below.

The positioning is the point. Radar units like the Garmin R10 sit behind the ball and want to see ball flight, which in practice means around 14 feet of total room depth for reliable indoor readings. A camera unit beside the ball needs far less. Square’s own comfortable-setup guidance is roughly 10 feet deep, 10 feet wide, and 9 feet tall, which describes an ordinary UK garage bay or garden room. If your space fails the radar test in our small garages guide, this category is where you should be looking.

UK price and what’s in the box

UK pricing sits at £699.99. In the box: the unit, charging cable, alignment aids, and three marked balls. There’s no compulsory subscription for core function, and its software connections don’t carry an extra connection fee, which is a genuine differentiator in a market where unlock fees and subscriptions are creeping into everything. Budget for extra marked balls over time as the supplied ones wear.

Accuracy: strong core numbers, honest weak spot

We haven’t lab-tested this unit ourselves; the picture below is assembled from published US testing and owner reports across the main simulator communities, which are unusually consistent about both the strength and the weakness.

The strength: core ball data. Side-by-side sessions against premium camera systems costing many times more report ball speed within 1 to 2 mph and carry distances within a couple of yards for most clubs. For a £700 unit, that’s the headline, and it’s why the value conversation keeps coming back to Square.

The weakness: directional dispersion, especially with the driver. Reports consistently note side-to-side error that can reach several yards with the longest clubs. In practice that means carry numbers and practice feedback you can trust, and shot-shape reads with driver that you should treat as indicative rather than gospel. For course play in GSPro that’s a modest annoyance; for someone specifically working on fixing a driver miss with precise start-line data, it’s the reason to look upmarket.

The marked-ball question. Square uses marked balls for its tracking, and this is the same running-cost consideration we flagged with the Rapsodo MLM2PRO in our three-way comparison: the sticker price isn’t quite the whole price if you’re committing to specific balls for best accuracy. It ships with three; heavy users will buy more.

Software: GSPro out of the box

The Square connects to GSPro and E6 Connect, alongside built-in courses on its own app. GSPro compatibility at this price is a big deal for UK buyers: GSPro is the enthusiast standard, and the R10 at a similar price point needs a third-party bridge to get there, while the MLM2PRO’s strength is its own Rapsodo ecosystem rather than open connection. If your plan is a proper GSPro setup in a garage on a sensible budget, Square is currently the cleanest route at this price. See our software comparison for how the platforms differ once you’re connected.

Square Golf vs Garmin R10 vs Rapsodo MLM2PRO

The decision logic is cleaner than most three-ways. Buy the Garmin R10 if you want one unit for the range and home, and you have the depth indoors. Buy the MLM2PRO if the Rapsodo app ecosystem and video replay appeal. Buy the Square if your space is tight, your destination is GSPro, and indoor practice is the main job. On pure indoor value per pound, the Square currently makes the strongest case of the three.

Who should actually buy it

Buy the Square Golf if: your room fails the radar depth test, you want GSPro without spending SkyTrak money, and your priority is trustworthy carry and speed numbers for practice and simulator rounds.

Look elsewhere if: you need precise driver shot-shape data (step up to a premium camera unit), you want one device that lives in your golf bag for the range (the R10 remains the pick), or you’d rather avoid marked balls entirely (see the SkyTrak options in our three-way comparison).

Frequently asked questions

How much does the Square Golf launch monitor cost in the UK? Around £699.99. It ships with three marked balls, and replacement marked balls are an ongoing cost worth factoring in for heavy use.

Is the Square Golf accurate? Published testing and owner reports consistently find ball speed and carry distance close to premium camera units, within 1 to 2 mph and a couple of yards for most clubs. The known weakness is side-to-side dispersion, especially with the driver, so treat shot-shape data with longer clubs as indicative.

How much space does the Square Golf need? Roughly 10 feet of depth, 10 feet of width, and 9 feet of ceiling for a comfortable full-swing setup. Because it’s camera-based and sits beside the ball, it suits small garages and garden rooms that radar units struggle in.

Does the Square Golf work with GSPro? Yes, it connects to GSPro and E6 Connect without an additional connection fee, alongside built-in courses in its own app. Native GSPro support at this price is one of its strongest selling points for UK buyers.

Do I have to use marked balls with it? The system is designed around its marked balls for tracking. It ships with three, and buying spares is part of the real running cost, similar to Rapsodo’s RPT ball requirement for full spin accuracy.
