If you’re shopping in the premium overhead category, chances are you’ve landed on the same two names everyone keeps circling back to: the ProTee VX and the Uneekor EYE XO2.
They’re both ceiling-mounted, camera-based launch monitors built for serious home simulators and commercial installs. They both give you the core ball and club metrics that actually matter. And they both plug into the gameplay ecosystem most golfers end up using anyway, especially GSPro.
So the question isn’t “Are these good?” They’re both good.
The real question is: what are you actually paying for with the EYE XO2, and what do you actually get for the money with the ProTee VX?
This post is structured the same way I’d explain it to a customer on a call. We’ll walk through price and subscriptions, hardware and what’s included, data and capabilities, software, hitting area, install and calibration, and then the big one: how the data compared when I tested both systems in the same sim space.
The quick snapshot
ProTee VX: A value-heavy overhead system with strong ball and club data, no marked balls required, and AI-driven club data that can reduce sticker dependency.
Uneekor EYE XO2: A more mature ecosystem with a three-camera design, a slightly larger hitting area, and a deep Uneekor software suite.
If you just want the high-level take before we go deep, here it is.
- ProTee VX is the “how is this this good for the price?” option. The ownership model is simpler, and it includes swing cameras.
- Uneekor EYE XO2 is the “fully built-out platform” option. You’re paying for an established ecosystem and a premium overhead experience that feels very complete.
Price and the real cost of ownership
ProTee VX: Lower up-front hardware price and typically fewer required recurring costs for core use.
Uneekor EYE XO2: Higher MSRP and more common recurring costs depending on how you use the Uneekor ecosystem and connectors.
Price isn’t everything. But in this category, the price gap is big enough that it forces a real conversation.
At the time of testing, the ProTee VX was priced at $6,500. The Uneekor EYE XO2 MSRP was $11,000 (it can go on sale, but MSRP-to-MSRP it’s a meaningful jump).
The bigger difference is what happens after you buy it.
Subscriptions and software costs
Most golfers who buy either of these end up adding GSPro for gameplay. GSPro is its own subscription, and you should plan for that if it’s your end goal.
Where it gets interesting is how each system connects into GSPro.
- The VX does not require a separate integration subscription for GSPro in the same way some ecosystems do.
- Uneekor’s GSPro workflow runs through Uneekor Launcher, which can introduce an additional recurring connector cost depending on the current Uneekor model and terms.
Uneekor also offers in-house course play through their ecosystem, which carries its own annual cost. ProTee has GolfCore coming, positioned as a bigger course-play option, but at the time of testing pricing was not confirmed.
If you want the simplest ownership model and fewer ongoing costs, VX is hard to ignore. If you want the most established “all-in” ecosystem today and don’t mind ongoing software costs, XO2 makes a strong case.
Hardware comparison and what’s included
ProTee VX: Two-camera overhead unit and includes two swing cameras with purchase.
Uneekor EYE XO2: Three-camera overhead unit with a premium hardware build and optional swing camera ecosystem.
On paper, both are overhead camera-based systems, but there are real differences worth calling out.
Camera count
The ProTee VX is a two-camera unit. The Uneekor EYE XO2 uses three cameras.
More cameras can support additional consistency and redundancy in how a unit captures impact and early ball flight. It doesn’t automatically mean “better,” but it is a meaningful difference in hardware design.
Mounting and placement
Mounting plates are provided on both. Typical placement is similar for both units: ceilings around 9–10 feet and positioning based on the recommended distance from the ball and hitting zone.
You’re not choosing between “easy to mount” and “hard to mount.” Both sit in the same install class.
Swing cameras
This is where the VX brings a lot of value. ProTee VX includes two swing cameras with the unit, which is a major add when you’re comparing total system value.
Data and launch monitor capabilities
ProTee VX: Full ball and club data set for sim and practice, with AI-driven club measurement that can reduce sticker use.
Uneekor EYE XO2: Full ball and club data set, with optional club stickers used for highest-confidence club metrics.
Ball data. Club data. And whether you can trust the results. That’s what people really care about.
In terms of what each unit can provide, both cover the data categories most golfers need for serious practice and gameplay.
Marked balls
Neither system requires marked balls. That’s a quality-of-life win. Less friction means more reps, and more reps is the entire point of having a simulator.
Club stickers and the VX AI angle
Uneekor can use club stickers to support club data capture accuracy. ProTee VX leans on AI-powered club data measurement that can reduce or eliminate the sticker workflow over time.
There’s an important nuance here: AI systems can improve as they learn a golfer’s delivery. That shows up in the testing section later.
Software comparison
ProTee VX: ProTee Labs for practice and testing, with expanding ecosystem (GolfCore mentioned as upcoming).
Uneekor EYE XO2: Uneekor View, Launcher, and a broader established suite including practice modes and in-house course play options.
Most buyers think they’re buying a launch monitor. In reality, you’re buying a workflow.
How you practice. How you play. How you connect. How smooth it feels when you walk into the room and want to hit golf balls.
GSPro
Most customers are going to be using GSPro for gameplay. Both connectors are fairly seamless. It’s a few clicks and you’re ready to go.
Practice software: ProTee Labs vs Uneekor View
Uneekor’s practice workflow lives inside View and related tools. ProTee’s practice experience centers on ProTee Labs.
Both are strong. The difference is look, feel, and how each company is building out the surrounding ecosystem.
Uneekor’s ecosystem advantage today
Today, Uneekor has the more established ecosystem. You have practice modes, in-house course play options, drills, and a suite that feels mature and complete.
ProTee is building quickly and GolfCore was positioned as a major step forward in the course-play ecosystem, but Uneekor has more “complete platform” depth right now.
Hitting area and real-world forgiveness
ProTee VX: Strong overhead hitting zone at roughly 25" x 21".
Uneekor EYE XO2: Slightly larger hitting zone at roughly 28" x 21", helped by three-camera design and Uneekor workflows.
Overhead systems live and die by their hitting zones.
If the zone is too small, people start making compromises: awkward ball positions, weird setup habits, and “why does this feel annoying?” friction that kills usage over time.
Both VX and XO2 are strong here, but XO2’s zone is a bit larger. That matters more in a multi-user sim room than most people expect.
Install and calibration
ProTee VX: Similar install difficulty to other overhead systems with straightforward calibration workflow.
Uneekor EYE XO2: Similar mounting complexity with calibration that’s familiar for the Uneekor platform.
Overhead install can feel intimidating, but the process is usually more straightforward than people think.
The practical flow is simple:
- Get the unit level
- Establish your alignment reference
- Calibrate to the hitting area
- Verify the zone is where you expect it to be
In the test, I tried to mount both units close enough to create overlapping hitting zones so I could measure the exact same shot on both units.
The attempted “same shot” test and what went wrong
ProTee VX: Flagged IR interference during simultaneous operation, which impacted spin capture workflow.
Uneekor EYE XO2: Uses infrared flash to capture spin, which can interfere with other camera-based systems running simultaneously.
The plan was to have both launch monitors capture the exact same swing by overlapping the hitting areas.
But ProTee Labs flagged external infrared light interference. The XO2 uses an infrared flash to capture spin, and that interfered with the VX’s ability to read spin accurately in that specific setup.
At that point, I didn’t feel comfortable continuing the “same shot” test. If spin capture is compromised, it contaminates the data set.
So we pivoted to a more realistic approach: full shot sets on each unit, tested separately.
Data test methodology
ProTee VX: Large sample testing set captured inside ProTee Labs with consistent environmental settings.
Uneekor EYE XO2: Large sample testing set captured inside Uneekor View with club stickers used and consistent environmental settings.
I hit large sample sets with wedge, eight iron, five iron, and driver on each system.
The goal was to capture meaningful averages and see if any patterns emerged across:
- Ball speed
- Launch and spin
- Carry
- Directional behavior
- Core club metrics
Testing conditions were normalized as much as possible: matching temperature settings, zero altitude, calibration immediately before the test, and club stickers used for Uneekor shots.
Also worth repeating: I’m not a swing robot. Human variability is real in any test like this.
Ball data results
ProTee VX: Ball data looked consistent and usable across clubs, with some carry outputs feeling slightly conservative.
Uneekor EYE XO2: Ball data looked consistent and usable, with reported ball speed trending slightly higher at higher speeds.
The headline is simple: I did not see a dramatic difference between the two units across most core ball metrics.
Ball speed, backspin, launch angle, and carry were broadly comparable.
The trend that stood out was at higher speeds. As club length increased, XO2 reported slightly higher ball speeds than VX in this test.
Without a control reference, I can’t conclusively say whether VX was light or XO2 was hot. My practical interpretation from the test was that XO2 looked a touch hot at the top end, especially with driver.
I also noted that VX’s carry algorithm looked slightly conservative, even when the raw inputs felt reasonable.
Consistency across both units looked strong given the human variability and the fact that extreme mishits were removed from the dataset.
Directional ball data
ProTee VX: Directional outputs tracked closely with XO2 across irons, with stable spin axis behavior.
Uneekor EYE XO2: Directional outputs tracked closely with VX, with more spin axis volatility showing up during higher-speed driver swings in this dataset.
Directional data can be influenced heavily by strike quality and human variability.
In this test, directional results were very comparable between VX and XO2. Spin axis was close to neutral through wedge, eight iron, and five iron. With driver, XO2 showed more volatility, but the swing pattern and strike quality were also less consistent in that portion of the test.
The honest takeaway is that both units produced directional ball results that made sense and were usable for gameplay and practice.
Club data and the AI learning effect
ProTee VX: Club data improved noticeably after the first set of swings, suggesting an AI learning curve on a fresh profile.
Uneekor EYE XO2: Strong club data workflow with stickers used for higher-confidence readings.
This was one of the most interesting parts of the entire test.
Uneekor used club stickers. That’s the established workflow.
ProTee VX used an AI-powered club data approach without stickers. Early on, face angle readings were clearly off in a way that didn’t pass the common-sense test.
Then, as more shots were hit, the VX club data started converging and became much more comparable to XO2. Within a relatively small number of swings, it seemed like the system “learned” my delivery.
Club speed, club path, and angle of attack looked consistent across both units and aligned with what I’d expect to see in real life.
The practical implication is important: if the VX can deliver stable club data without stickers after a short learning curve, that’s a major quality-of-life advantage for many buyers.
Final verdict
ProTee VX: Best overall value if you want premium overhead performance with lower ownership cost and strong practice workflow.
Uneekor EYE XO2: Best overall ecosystem depth today if you want a mature software suite and platform completeness.
Data-wise, both systems looked strong. Neither one raised red flags that would make me say “avoid this.” Both are absolutely viable for a premium home build.
If you want the cleanest way to think about the decision, it’s this.
Choose ProTee VX if you want the best value in the overhead category, you want to minimize ongoing costs, you like the AI-driven club data approach, and you want swing cameras included.
Choose Uneekor EYE XO2 if you want the most established ecosystem today, you value the three-camera design and slightly larger hitting area, and you want the Uneekor platform depth even if it costs more to run long-term.
You’re going to get value out of either one. See our PDF summary of the full data test to check out the results for yourself.
