The Square Golf Launch Monitor, Judged on Specs, Costs and Owner Reports

Square Golf makes a small, camera-based launch monitor that sits beside the ball and is listed at about $699.99 at time of writing. It needs no subscription to get started, and it's aimed at people who want ball and club data in a spare room rather than a dedicated bay. For indoor practice, putting and chipping in a modest room, it's a reasonable fit. If you need club speed or smash factor on the day you buy, it isn't.

That short answer depends on details that marketing tends to skip. Room depth, handedness, the credit system and which software costs extra all change what you actually pay and what you get. This review works from the published specs, the maker's documentation and what owners report, and it does its own arithmetic on running costs.

Verdict in one paragraph

The Square Golf is a compact, no-subscription camera unit that suits indoor home practice in a short room, along with putting and chipping. The trade-offs are real. At time of writing the published data set doesn't include clubhead speed or smash factor, spin readings are better with Square's marked balls, the unit has to be moved for left-handed players, and it is built for indoor use. Because the maker's data list can change, check the current spec sheet before you buy. Don't confuse it with the Square Omni, which is listed at about $1,599 and is positioned for both indoor and outdoor use. We cover that split in the Square Omni review.

Good fit, poor fit

Buyers it suits

• Home golfers with a small room or spare bedroom
• Players who don't want yearly fees on top of the hardware
• Golfers who want putting and chipping reads indoors
• Families who want casual sim rounds through GSPro or the included courses
• First-time launch monitor buyers who want a lower entry point

Buyers who should look elsewhere

• Players tuning swing efficiency who need club speed and smash factor. This is the biggest gap in the data set, so check the current list before you buy.
• Golfers who mostly practise at an outdoor range. The best golf simulators for outdoor use guide and the FlightScope Mevo+ review cover that case better.
• Mixed left- and right-handed households who swap players often
• Coaches who need swing video and deep club data

What the spec sheet leaves out

A spec table tells you what a device is supposed to do, but it doesn't tell you how that feels across a month of use. The Square Golf is small and light, which helps when you want to store it between sessions or move it around a room. The flip side is that a small unit has to be positioned accurately every time, because the cameras only see what they're pointed at. If you're the sort of player who likes to change the room layout often, that positioning step becomes part of your routine rather than a one-off job.

Battery life is also worth thinking about. The maker's claim of about 8 hours is a useful guide for a session or two, but it won't tell you how the battery holds up after a year of charging. Ask the dealer how battery service works before you buy, since that's the question that matters most for a portable unit over several years.

Data it reports, and the gaps

Category	What it covers
Ball data	Ball speed, launch direction, launch angle, spin rate, apex, carry, run and total distance
Club data	Swing path, face angle, dynamic loft and angle of attack
Missing at time of writing	Clubhead speed and smash factor. Check Square's release notes for any change.
Spin axis	Owner and reviewer reports suggest it may be estimated from face and path rather than measured directly

The gaps matter more than the list. Without smash factor you have no direct read on how efficiently you're striking the ball. Clubhead speed is also the usual starting point for working out the distance gap between clubs. If your goal is to tune strike and gap yardages, look at the monitors with deeper club data before you commit.

How a camera unit like this sees the ball

Two cameras and infrared sensors capture the ball at and just after impact. The flight is then calculated rather than tracked along its whole path. That is the main practical difference from radar, and it explains why the unit needs so little room. There's no long ball flight to follow, so the unit only has to see the moment of impact clearly. For the wider picture, read how launch monitors work and the radar vs camera comparison.

Marked balls aren't required, but Square's pre-marked 2-piece and 3-piece balls are reported to improve spin readings. Other infrared devices in the room can interfere with the sensors, so if readings look erratic, check for them. Keep strong lights out of the camera's view as well. Those two habits do more for consistent readings than any setting in the app.

Room size and daily setup

Published comparisons cite roughly 10 ft of total depth as workable for this unit. A radar unit such as the Mevo+ is cited at about 16 to 18 ft. Check Square's own guidance for the exact figure before you measure your room.

Worked example: a 12 ft deep spare room

• The room is 12 ft deep, which clears the roughly 10 ft the Square Golf is cited as needing.
• The room falls short of the 16 to 18 ft cited for a rear-mounted radar unit, so a radar unit set up that way would not fit.
• With the net 7 to 8 ft from the ball, that leaves roughly 4 to 5 ft behind the ball for the golfer and the swing.
• The Square Golf sits beside the ball, facing the golfer, so the layout works in that room.

Left-handed players need the unit moved to the opposite side and re-aligned. If your household swaps players, build that into each session. The app's alignment guides help with placement, and owners describe setup as quick once the unit is in position. Low-speed putts register from about 1.6 mph according to the published specs, so check that number against the current manual. For room planning in general, see golf simulator room size and best golf simulators for small spaces.

Setting up each session

Plan the first few sessions as a learning period. Set the unit beside the ball, check the alignment guides in the app, and hit a short series of shots to confirm the readings look sensible before you start a practice routine. Once you know your spot, the setup becomes quick, and owners describe it that way. The step that takes longest is usually the first alignment, not the daily routine after it.

If more than one person uses the unit, write down the placement for each player. A left-handed golfer needs the unit on the opposite side, so a quick note or a marked spot on the floor saves time and keeps readings consistent between sessions.

Software: credits, GSPro and the built-in modes

Item	Detail
Included credits	1,000 course credits, one per hole in Square's course mode
Credit maths	About 55 eighteen-hole rounds from 1,000 credits, by our math
Range and putting	No credits used
GSPro	Reported to use no Square credits. The GSPro licence is a separate purchase, about $250 a year at time of writing.
Other titles	E6 Connect and The Golf Club are listed as compatible. Check the current list.
App features	Shot history, sort by club, saved sessions, player profiles, multiplayer mode and cloud storage
Paid tier	Some reviews mention an optional paid tier for extras such as video analysis or backups. That conflicts with the no-subscription message, so ask Square directly before you buy.

The credit model is the unusual part. Credits are spent only in course mode, one per hole, so a lot of practice never touches them. Range and putting sessions are free to run, and a GSPro round doesn't draw on the Square balance. If you want to understand the wider cost picture, read the launch monitors without a subscription guide.

Where it falls short indoors

The biggest limit is the data set. Without clubhead speed or smash factor, the Square Golf can show you where the ball went and how it spun, but it won't tell you how efficiently you struck it. Players who want to measure strike quality over time will feel that gap quickly. The second limit is the room itself. A unit that depends on a short, controlled space works well in a spare room, but it doesn't suit a setup where the room changes often or where you want to hit in a large open area.

Light and other infrared sources are the practical risks. Bright lamps, sunlight through a window or other infrared devices can all make readings less consistent. None of that is a dealbreaker in a well-controlled room, but it's a reason to pick a dedicated, dark spot for the unit rather than wherever happens to be free.

Add-ons: the Swing Stick and marked balls

The Swing Stick is an accessory for swinging indoors without hitting a real ball. Reviewers frame it as fun for casual play and for children rather than as a serious training tool, so don't buy it expecting swing coaching. Check the current price before you add it to a basket. Marked balls come in 2-piece and 3-piece options sold by Square, and they are the simplest way to improve spin capture. Some sellers bundle an optional travel case, so ask what's included when you order.

Where the price stops being the whole story

The sticker price is the number most buyers compare first, but the total cost depends on how you practise. A player who uses only range and putting sessions will rarely touch the credit balance, so the Square Golf can be cheap to run. A player who plays a lot of course mode will spend credits steadily, and a top-up is a recurring cost even without a subscription. Work out roughly how many holes you expect to play in a month before you decide whether the included credits are enough.

GSPro changes the picture because it's a separate licence that sits on top of the hardware. If you plan to use GSPro for most of your sim time, budget for it from the start rather than treating it as an optional extra.

Three years of ownership, priced

Worked example: three years with GSPro

• Unit: about $699.99 at time of writing
• Software to start: $0, since no software purchase is required
• GSPro: about $250 a year, so $750 over three years by our math
• Three-year total: about $1,450 before marked balls and credit top-ups

Marked balls and credit top-ups are priced by Square at the time of purchase, so check those before you set a budget. The total above is the floor for a GSPro setup, not the full cost.

Compare that with monitors that charge yearly software fees at a similar purchase price. Those fees add to the total every year, so the three-year figure can end up well above the sticker price. The Rapsodo MLM2PRO review and our guide to golf simulator software subscription models show how those fees stack up.

Who gets the most from the price

The Square Golf makes the most sense for someone who wants a low-cost, low-commitment way into launch monitor practice. If you mainly want to work on your putting, chipping or short-game feel indoors, the data set is more than enough. Families who want to play casual rounds through GSPro or the included courses also get a lot of fun from it without paying a yearly fee.

It makes less sense for someone who wants detailed strike data or who wants to take the unit outdoors often. In those cases the extra money for a larger or different system tends to pay back in data you'll actually use, rather than in features you'll rarely open.

Square Golf beside nearby alternatives

The Square Golf and the Square Omni share a name and not much else. The table sets out the differences the published details support.

Item	Square Golf	Square Omni
Listed price at time of writing	About $699.99	About $1,599
Positioning	Indoor, compact	Indoor and outdoor
Club data	Path, face angle, dynamic loft and angle of attack in the app	Sticker-based club data
Display	Phone or tablet app	On-unit display

Cross-shopping usually comes down to outdoor use, the depth of club data you need and whether a yearly fee fits your budget. For a direct comparison, see Square Golf vs Mevo+ and Square Golf or the original SkyTrak. Those pages sit alongside the original SkyTrak review, the Rapsodo MLM2PRO review and the Mevo+ vs Garmin R10 comparison, so you can see how each option stacks up on your priorities. Don't merge the Omni into this review. It is a larger, separate product, and its numbers belong on its own page.

Warranty, returns and support

• Register the unit for the 12-month warranty
• Check the return window with the seller. Thirty days is common for unused items, but it varies.
• Buy from an authorised dealer to keep warranty handling simple
• Ask the dealer how battery service is handled. Battery wear is the likeliest long-term issue for any portable unit.

Questions owners ask in the first month

These questions cover the points that matter most in the first month of use.

What happens when the included credits run out?

Credits are used only in Square's course mode, at one per hole, and 1,000 credits cover roughly 55 full rounds by our math. Top-ups are bought from Square, so check the current price there. Range, putting and GSPro play carry on without them.

Can it read short putts on an indoor green?

Published specs list putts from about 1.6 mph, so check that number against the current manual. Camera units are generally described as handling slow shots better than radar units, which need the ball to move before they lock on. For how putting reads work on simulators in general, see how simulator putting works.

Does it need a PC, or will a phone do?

The Square app runs on iOS and Android, so a phone or tablet handles the app side. GSPro requires a Windows PC. Check each sim title's device requirements before you buy.

Will it work outside on a sunny range?

The unit is positioned mainly for indoor use, and some owners use it in shade outdoors. Strong light can interfere with the camera, so keep bright sun out of its view. For range use, look at the Square Omni or a radar unit.

Is the Square Omni just an upgraded version of this unit?

No. The Omni is a separate, larger model listed at about $1,599 at time of writing, with an on-unit display, indoor and outdoor positioning, and sticker-based club data. The original Square Golf is the compact, roughly $700 indoor unit.
