What They Have in Common
Both run on a one-time purchase with no subscription attached — the Shot Scope app is free, and the Square Golf includes 10 courses plus GSPro compatibility out of the box. Both use Bluetooth to connect to your device. That's roughly where the overlap ends.
Where They Differ
Technology & What Each One Can Actually Measure
The LM1 is a Doppler radar unit. It tracks what the ball does after impact — ball speed, carry, total distance, club speed, smash factor. Five metrics. That's it. For a $200 radar unit, that's about what you'd expect.
The Square Golf Original is a photometric camera system that sits beside the ball and uses high-speed machine vision to capture impact. It tracks eleven metrics: ball speed, direction, launch angle, spin rate, apex, carry, total distance, swing path, face angle, dynamic loft, and angle of attack. That's club data and ball data in a single device with no add-ons required.
The difference matters because spin rate and launch angle are what actually tell you why your 7-iron is coming up short. Ball speed alone doesn't answer that question. If you're trying to optimize your ball flight or dial in a new shaft, the LM1 gives you part of the story. The Square Golf gives you most of it.
Indoor vs Outdoor Use
This is the clearest split between these two devices. The LM1 works indoors and outdoors. The Square Golf is indoor-only — it needs a net or hitting screen, and it won't function as an outdoor range device.
If you want something to use at the driving range on Saturday morning, only the LM1 does that. The LM1 also has a built-in 3.5" color display, so you're not squinting at your phone in the sun between shots.
The Square Golf is designed for a dedicated hitting space. If you have one, great. If you don't, it's the wrong tool.
Special Ball Requirements
The Square Golf requires dotted balls for accurate readings. This is worth pausing on. Dotted or special pattern balls typically run $50–$70 per dozen. If you're hitting 50 balls a day, five days a week, that adds up. It's not a subscription, but it's an ongoing cost that the sticker price doesn't reflect. Factor in roughly $150–$250 per year in balls if you're practicing seriously.
The LM1 works with any ball. Show up with whatever's already in your bag.
Simulation and Course Access
The Square Golf connects to GSPro and includes 10 courses. GSPro's library runs into the thousands of courses, so if you already have a GSPro license, you're plugging into a mature ecosystem. The 10 included courses give you something to play on day one without any additional spend.
The Shot Scope app is free but isn't a simulation platform — it's a practice and shot-tracking app. The LM1 doesn't appear to connect to GSPro or E6 or any sim software based on what's in the spec data. If simulation is why you want a launch monitor, the LM1 isn't that product.
Battery Life and Build
The LM1 gets about 5 hours on a charge via USB-C. The Square Golf gets 8 hours and has a removable battery — useful if you're running long sim sessions and don't want to stop to plug in. The LM1 carries an IPX3 weather resistance rating, which makes sense given it's built for outdoor use. The Square Golf has a 2-year warranty.
Who Should Buy Which
Shot Scope LM1 — you're the golfer who:
- Practices mostly at the range and wants a quick, honest read on carry distances without pulling out your phone
- Wants to track progress in club speed and smash factor over time using the Speed Training mode
- Has a $200 budget and needs something that actually works outdoors in real conditions
- Isn't building a sim room — you just want better data than your eyes can give you
Square Golf Original — you're the golfer who:
- Has a net or hitting screen at home and wants to turn it into a legitimate sim setup
- Is tired of practicing without knowing your spin rate, attack angle, or face angle — the data you actually need to improve
- Already has or is planning to get a GSPro license
- Can factor in the cost of dotted balls as part of your setup budget and is okay with indoor-only use
The Bottom Line
At $200, the LM1 is one of the few portable radar units with a built-in screen and no subscription, and it earns its place in a range bag. But it's measuring a fraction of what the Square Golf tracks, and it won't run a sim setup.
The Square Golf Original is genuinely a different class of device. Camera-based club data, GSPro integration, 10 included courses, 8-hour removable battery — all for $699 with no ongoing software fees. The dotted ball requirement is real, so build that into your math. But if indoor sim or serious ball flight work is what you're after, the LM1 isn't a stepping stone to this — it's a different product entirely.
