If you are shopping in the premium overhead category, chances are you have landed on the same two names everyone keeps circling back to: the ProTee VX and the Uneekor EYE XO2.
They are 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 is not "are these good?" They are 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 we would explain it to a customer on a call: price and subscriptions, hardware and what is included, data and capabilities, software, hitting area, install and calibration, and then the big one, how the data compared when we tested both systems in the same sim space. Watch the full hands-on comparison here, then read the section-by-section breakdown below.
The short version
ProTee VX is the "how is this this good for the price?" option. A value-heavy overhead system with strong ball and club data, no marked balls required, AI-driven club data that can reduce sticker dependency, and swing cameras included.
Uneekor EYE XO2 is the "fully built-out platform" option. A more mature ecosystem with a three-camera design, a slightly larger hitting area, and a deep Uneekor software suite.
Price and the real cost of ownership
On MSRP, the ProTee VX sits well below the EYE XO2. The gap is large enough that it forces a real conversation about what you are paying for. Pricing moves with sales and bundles, so check the current numbers on each product page linked below. 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, so plan for that if it is 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 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, the VX is hard to ignore. If you want the most established all-in ecosystem today and do not mind ongoing software costs, the XO2 makes a strong case.
Not sure which one fits your ceiling height, budget, and how you actually plan to use the room? That is exactly the call we have every day.
Get a Personalized PickHardware and what is included
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 does not 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: ceilings around 9 to 10 feet, positioned based on the recommended distance from the ball and hitting zone. You are 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. The ProTee VX includes two swing cameras with the unit, which is a major add when you are comparing total system value. On the Uneekor side, swing cameras are part of an optional ecosystem.
Data and launch monitor capabilities
Ball data. Club data. And whether you can trust the results. That is what people really care about. Both units cover the data categories most golfers need for serious practice and gameplay.
Marked balls
Neither system requires marked balls. That is 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 is an important nuance here: AI systems can improve as they learn a golfer's delivery. That shows up in the testing section below.
Software: you are buying a workflow
Most buyers think they are buying a launch monitor. In reality, you are buying a workflow. How you practice. How you play. How smooth it feels when you walk into the room and just want to hit golf balls.
GSPro
Most customers are going to use GSPro for gameplay. Both connectors are fairly seamless. A few clicks and you are 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: practice modes, in-house course play options, drills, and a suite that feels mature and complete. ProTee is building quickly, and GolfCore is positioned as a major step forward in course play, but Uneekor has more complete-platform depth right now.
Hitting area and real-world forgiveness
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 friction that kills usage over time.
The ProTee VX has a strong overhead hitting zone at roughly 25 by 21 inches. The Uneekor EYE XO2 runs slightly larger at roughly 28 by 21 inches, helped by the three-camera design. Both are strong, but the XO2's larger zone matters more in a multi-user sim room than most people expect.
Install and calibration
Overhead install can feel intimidating, but the process is usually more straightforward than people think. Both units follow the same practical flow:
- Get the unit level
- Establish your alignment reference
- Calibrate to the hitting area
- Verify the zone is where you expect it to be
For the test, we tried to mount both units close enough to create overlapping hitting zones so we could measure the exact same shot on both.
The stuff nobody talks about: when the test went sideways
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 we did not 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. Worth knowing if you ever plan to run two camera-based systems in the same bay at once.
How we tested the data
We hit large sample sets with wedge, eight iron, five iron, and driver on each system, captured inside each unit's native software (Uneekor View with club stickers on the XO2, ProTee Labs on the VX). Conditions were normalized as much as possible: matching temperature settings, zero altitude, calibration immediately before the test. One honest caveat: we are not swing robots, so human variability is real in any test like this.
Ball data results
The headline is simple: we 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, the XO2 reported slightly higher ball speeds than the VX in this test. Without a control reference we cannot conclusively say whether the VX was light or the XO2 was hot, but our practical read was that the XO2 looked a touch hot at the top end, especially with driver, and the VX's carry algorithm looked slightly conservative even when the raw inputs felt reasonable. Consistency across both units looked strong once extreme mishits were removed.
Directional ball data
Directional data is influenced heavily by strike quality and human variability. In this test, directional results were very comparable between the VX and XO2. Spin axis was close to neutral through wedge, eight iron, and five iron. With driver, the XO2 showed more volatility, but the swing pattern and strike quality were also less consistent in that portion of the test. The honest takeaway: both units produced directional ball results that made sense and were usable for gameplay and practice.
Club data and the AI learning effect
This was one of the most interesting parts of the entire test. Uneekor used club stickers, 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 did not pass the common-sense test.
Then, as more shots were hit, the VX club data started converging and became much more comparable to the XO2. Within a relatively small number of swings, it seemed like the system learned our delivery. Club speed, club path, and angle of attack looked consistent across both units. The practical implication is important: if the VX can deliver stable club data without stickers after a short learning curve, that is a major quality-of-life advantage for many buyers.
The verdict: which one should you buy?
Data-wise, both systems looked strong. Neither one raised red flags that would make us say avoid this. Both are absolutely viable for a premium home build. Here is the cleanest way to think about the decision.
Choose the 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.
Best for: Value-focused buyers who want premium overhead performance with the simplest ownership model.
Choose the 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 Uneekor platform depth even if it costs more to run long term.
Best for: Buyers who want the most complete, mature overhead platform and the bigger hitting zone for a multi-user room.

Talk to the Sim SquadFAQ
Is the ProTee VX as accurate as the Uneekor EYE XO2?
In our side-by-side testing, ball data was broadly comparable across both units for ball speed, spin, launch, and carry. The XO2 trended slightly higher on ball speed at the top end with driver. Both produced usable, trustworthy data for serious practice and gameplay.
Does the ProTee VX need club stickers or marked balls?
No. Neither the VX nor the XO2 requires marked balls. The VX also skips club stickers in favor of AI-driven club data, which converged to comparable readings after a short learning curve in our test. The XO2 uses club stickers for its highest-confidence club metrics.
Which has the bigger hitting area?
The Uneekor EYE XO2, at roughly 28 by 21 inches versus roughly 25 by 21 inches on the ProTee VX. The larger zone matters most in a multi-user sim room.
Can I run both launch monitors in the same bay at once?
It is tricky. In our test, the XO2's infrared spin-capture flash interfered with the VX's spin reading when both ran simultaneously. If you plan to run two camera-based systems in one space, expect to test them separately rather than on the same shot.
Do both work with GSPro?
Yes. Both connect to GSPro and the setup is straightforward for each. Note that Uneekor's GSPro workflow runs through Uneekor Launcher, which can carry an additional connector cost depending on the current model and terms.
Which one should I buy?
Choose the ProTee VX for the best value, lowest ongoing cost, and included swing cameras. Choose the Uneekor EYE XO2 for the most mature software ecosystem and the larger hitting zone. Both are excellent premium overhead options.
