What They Have in Common
Both are Tier 1 portable launch monitors that work indoors and outdoors, use any ball (no special models required), and track the core metrics you'd expect at this price — ball speed, spin, launch angle, carry distance, club speed, smash factor, club path, and attack angle. Neither is cheap, and neither is aimed at the casual weekend golfer.
Where They Differ
Technology: Radar + Camera Fusion vs. Pure Photometric
This is the fundamental split. The Full Swing KIT uses a 24GHz dual-mode radar paired with a built-in camera — essentially two systems working together. The EYE Mini is purely photometric: two high-speed cameras mounted at ground level capturing the ball and club face through impact.
Camera-based systems have a real edge in spin accuracy, especially indoors. Radar units measure spin indirectly through ball flight modeling, which works well outdoors but can get shaky in short indoor spaces where there's not enough flight to lock in the numbers. The KIT mitigates this with its camera component, but I'd still give the edge in raw indoor spin accuracy to the EYE Mini's pure photometric approach — that's just what camera-based systems do well.
Outdoors, radar tends to track ball flight longer and more reliably. The KIT's dual-mode setup probably helps it in mixed environments. If I had to bet on which handles a windy outdoor range session better, I'd lean KIT.
What You're Actually Paying Over Time
Sticker prices: KIT at $4,999, EYE Mini at $4,500.
That $499 gap flips once subscriptions enter the picture. The KIT has no mandatory subscription — you get all 16 data points, E6 Connect, and GSPro compatibility with the hardware purchase. There's an optional $100/year cloud storage add-on if you want video synced to your account, but skipping it costs you nothing functionally.
The EYE Mini's free "Player" tier gives you ball and club data, which is solid. But to connect it to GSPro, E6, or any third-party simulator, you need the Pro tier at $199/year. That's the tier most buyers at this level actually want.
Three-year total cost of ownership:
- KIT: $4,999 (plus $300 if you want cloud storage every year)
- EYE Mini: $4,500 + $597 in Pro subscriptions = $5,097
By year three, the EYE Mini costs more than the KIT, and that gap widens from there.
Built-in Screen vs. Tethered to a Device
The KIT has a 5.3-inch Full HD OLED display built in. You can take it to the range, set it down behind the ball, and read your numbers — no phone, no iPad, no Wi-Fi required. That matters more than people think when you're on a range that doesn't have reliable connectivity.
The EYE Mini has no built-in display. You're running it through an iPad or a PC. That's fine for a dedicated sim room setup, but it's an extra dependency. If you're taking it to the range, you're squinting at an iPad screen in afternoon sun, or tethering to a phone hotspot to get data flowing.
Club Stickers
The EYE Mini requires metallic club face stickers to track club data. This is standard for photometric systems and it works, but it's worth knowing: stickers aren't legal in tournament play, so you'll be removing and reapplying them if you're also playing competitive rounds with the same clubs. The KIT doesn't require stickers for anything.
Portability
Both are marketed as portable. The EYE Mini weighs 7 lb 15 oz — that's real, measurable portability. Full Swing hasn't published the KIT's weight, which is a small frustration. The KIT's dimensions (10.23 x 6.57 x 2.32 in) suggest it's slim, but without a weight number, "portable" is harder to verify on paper. Worth handling both if you can before buying.
Who Should Buy Which
Full Swing KIT
- You want a launch monitor you can use at the range on a Tuesday morning without bringing an iPad and hunting for Wi-Fi.
- You're already planning to use GSPro or E6 and don't want a recurring fee to unlock that.
- You want swing video replay integrated into the same device — not a separate camera setup.
- You expect to own this for 4+ years and don't want subscription costs creeping up on you.
- You're buying for a mixed indoor/outdoor setup and want one device that handles both well.
Uneekor EYE Mini
- You're building a dedicated sim room with a permanent iPad or PC at the hitting station, and the "no display" limitation genuinely doesn't bother you.
- You prioritize indoor spin accuracy above almost everything else and want pure photometric data.
- You're okay with the Pro subscription at $199/year because you were already planning to pay for a simulator platform separately.
- You're coming from another Uneekor product and are already in their software ecosystem.
The Bottom Line
These are close. Closer than the price gap makes them look, and further apart once you run the subscription math. The EYE Mini is a strong photometric monitor with real indoor spin accuracy — but it costs more to operate, requires stickers, and needs an external display to function at all. The KIT costs more upfront and delivers more out of the box: standalone display, no subscriptions to unlock what you already paid for, video replay, and freedom from sticker management.
For most buyers choosing between these two, that's the right call.
