What They Have in Common
Both are subscription-free, app-only (no built-in screen), and include sim software out of the box — the Mevo with E6 Connect and 8 courses, the Square Golf with 10 courses and GSPro compatibility. Neither requires club face stickers for club data. That's a meaningful baseline overlap given how many competitors at these tiers are quietly charging you $200 a year for data access.
Where They Differ
Technology & What That Means for Accuracy
These two products are built on completely different foundations, and it matters.
The Mevo Gen 2 uses FlightScope's Fusion Tracking — a combination of 3D Doppler radar and image processing working together. The Square Golf Original is a beside-ball photometric unit, meaning a high-speed camera is watching the ball and club as they move through the hitting area. Each approach has real strengths and real weaknesses.
Radar is excellent outdoors and good at tracking ball flight over distance. Camera-based systems typically produce stronger spin data at short distances, but they need controlled lighting and a specific setup position. The Square Golf sits beside the ball, not behind it, which affects what it can and can't see. I'd guess spin accuracy from the Square Golf is solid in a dedicated indoor space with consistent lighting — but I don't work at Square Golf, and real-world results in less-than-ideal setups could vary.
The Mevo Gen 2 works outdoors without limitation. The Square Golf explicitly does not. If you ever want to use your launch monitor at a real driving range, the Square Golf is off the table.
Special Ball Requirements
This is a big one. The Square Golf Original requires dotted balls for its best data. These aren't standard range balls — they're specific balls with a dot pattern the camera uses as a reference for spin calculation. Budget for this: photometric systems typically use balls priced around $50–70 per dozen, and if you're practicing weekly, that adds up. The Mevo Gen 2 works with any ball, no special equipment needed.
This isn't just a cost issue. If you hit range balls at a public facility with the Square Golf, your data quality will suffer. If you hit range balls with the Mevo, you're fine.
Sim Software & Course Access
The Mevo Gen 2 includes a lifetime E6 Connect license with 8 courses, and it connects to GSPro without a fee. E6 is polished, runs well on PC, and has broad sim room adoption. GSPro is the darling of the serious home sim community for its course quality and active development. Having both without paying extra is genuinely good.
The Square Golf includes 10 courses and is GSPro compatible. Without knowing which 10 courses are in the Square Golf bundle, it's hard to compare directly — but the GSPro compatibility on both products means you're not locked into a proprietary software ecosystem on either.
Setup, Space & Portability
The Mevo Gen 2 needs to sit behind the ball — standard for radar units. It's under a pound and runs 6 hours on a charge, making it the obvious choice if you want something that goes in your bag on a Saturday.
The Square Golf sits beside the ball, which actually works better for some indoor setups with limited depth. It runs 8 hours on a removable battery — notable because you can swap batteries instead of waiting for a charge. At 7.5 inches long it's compact.
Neither has a built-in display. You'll need your phone, tablet, or laptop on both.
Warranty
The Square Golf's 2-year warranty versus the Mevo Gen 2's 12 months is a meaningful difference at these price points. A launch monitor is an electronics purchase that sees some physical stress. Two years of coverage matters.
Who Should Buy Which
FlightScope Mevo Gen 2 ($1,299)
- You play outdoors regularly and want to know your real carry numbers on an actual range, not just in a sim room
- You want to throw any ball in front of the unit and get clean data — no special ball logistics
- You're building a hybrid setup that lives both indoors and outdoors
- You want GSPro and E6 Connect without choosing between them
- You're already spending $1,000+ and the extra $600 feels proportionate to what you get
Square Golf Original ($699)
- You're building a dedicated indoor sim room and it will never move
- You're on a firm budget and the $600 gap matters
- You're comfortable managing a separate supply of dotted balls for practice
- You want a longer warranty on your hardware investment
- You've already priced out GSPro and know the Square Golf's included courses cover what you want
The Bottom Line
If you can use a launch monitor outdoors and care about hitting any ball you own, the Mevo Gen 2 earns its premium. The no-subscription model, any-ball compatibility, outdoor capability, and dual sim software access make it a genuinely complete package. The Square Golf Original is compelling at $699 if your use case is specifically indoor-only — but the special ball requirement is a real ongoing cost and inconvenience that closes some of that $600 gap. Run the math on dotted balls at your practice frequency: if you're hitting 3 times a week, you might spend $150–200 a year on balls, which means the Square Golf's effective year-1 cost is closer to $850–900.
