What They Have in Common
Both are subscription-free, which matters. You pay once and you're done — no monthly fees eating into the value proposition over time. Both work without club stickers. And both are portable enough to set up and put away. That's roughly where the similarities end.
Where They Differ
Technology and what it can actually measure
The Shot Mate uses Doppler radar — a K-band 24 GHz sensor that bounces a signal off the ball and club head in motion. Radar is great outdoors, decent indoors with enough space, and gives you clean speed and distance data. What it can't do is measure spin. Spin requires either a camera that can see the ball rotating or special radar processing that this unit doesn't have. So you get club speed, ball speed, smash factor, and carry/total distance. Four numbers. That's it.
The Square Golf Original uses a high-speed camera with machine vision — it sits beside the ball and photographs the shot at high frame rates. Camera systems can read actual spin because they're capturing what the ball is doing through impact and into early flight. The Square Golf gives you 11 metrics: ball speed, direction, launch angle, spin rate, apex, carry, total distance, swing path, face angle, dynamic loft, and angle of attack. That's a legitimate data picture of your swing.
Catch: the Square Golf requires marked balls (dotted balls) to track spin. Those aren't included in the sticker price. Budget accordingly.
What you're paying for — and what you're paying ongoing
Shot Mate: $179.99, no subscription, no special balls. That's the full cost of ownership in year one, year three, and year five.
Square Golf Original: $699, no subscription, but you'll need marked balls for full spin tracking. Dotted golf balls run around $35–50 for a sleeve depending on where you buy them. If you're practicing weekly, that adds up. At three years in, the Shot Mate probably costs you $180 total. The Square Golf could run $800–1,000+ depending on how many marked balls you go through.
Neither has a subscription, which is genuinely refreshing at these price points.
Indoor vs outdoor — a hard constraint
The Square Golf Original is indoor only. It won't work at the range, on a simulator at a golf bar, or in your driveway. It needs controlled lighting and a stable setup. If you want to use a launch monitor at the driving range on a Saturday morning, this isn't your device.
The Shot Mate works both indoors and outdoors. GolfBuddy even gave it a waterproof port, so light rain isn't a concern. It has a kickstand, a built-in TFT LCD display, and requires no phone or app. Set it down, swing, read the numbers. That standalone experience is genuinely useful when you're at a busy range and don't want to fiddle with Bluetooth pairing.
Simulator software and course play
The Square Golf Original connects to GSPro via Bluetooth and includes 10 courses. If you want to play sim golf at home, this is a real option — camera data feeds the sim accurately enough to use. The Shot Mate has zero sim capability. It's a numbers display, not a simulator input. GolfBuddy publishes no connectivity specs because there's nothing to connect to.
Data storage and standalone use
The Shot Mate stores 1,000 swings on-device. No app, no cloud, no phone required. It also has a Practice Swing Mode that reads club speed without a ball — useful for speed training with a weighted club or SuperSpeed sticks. The Square Golf requires a phone, tablet, or PC via Bluetooth to display any data. If your setup doesn't have a screen nearby, you're stuck.
Who Should Buy Which
GolfBuddy Shot Mate — you're the golfer who:
- Wants to start tracking carry distances without spending more than $200
- Hits the range two or three times a week and wants fast, frictionless feedback
- Doesn't care about spin data or simulator golf — you just want to know if your 7-iron is actually going 165 yards
- Does overspeed training and wants club speed readings without hitting balls
- Travels or moves between ranges and needs something you can toss in your bag
Square Golf Original — you're the golfer who:
- Has a dedicated indoor hitting space — a garage bay, basement, or spare room with a net
- Wants to play sim rounds at home and doesn't want to pay a monthly subscription to do it
- Is actively working on their swing and needs real data: spin, attack angle, face angle — not just speed and distance
- Has a coach or is self-coaching with video and wants numbers that actually explain shot shape
- Is willing to use marked balls and buy replacements as needed
The Bottom Line
The Shot Mate is a simple tool that does what it says for $180 with zero ongoing costs. The Square Golf Original is a legitimate entry-level sim launch monitor that captures real spin data and connects to GSPro — but it's $699, indoor only, and needs special balls to work fully. Most golfers should start with the Shot Mate. If you know you want an indoor sim setup and want camera-based accuracy without a subscription, the Square Golf Original is a reasonable buy.
