Originally published following the launch of the Garmin Approach R50, this article has been completely rewritten in September 2026. The first meaningful accuracy comparisons date mainly from late 2024 and the first half of 2025. Since then, users have had much more time with the device and Garmin has significantly developed its software. We have therefore revisited our original analysis, separating what the available measurements actually demonstrate from what still needs to be verified.
When the Garmin Approach R50 arrived in late 2024, it had almost everything required to shake up the launch monitor market. Three high-speed cameras, more than 15 ball and club metrics, a 10-inch — 25.4 cm — colour touchscreen and, crucially, the ability to use the device without an additional computer or tablet.
Garmin launched it in Europe at a premium price, but still far below the cost associated with the professional systems against which the R50 was immediately compared. The manufacturer also promoted access to more than 43,000 courses through Home Tee Hero, up to four hours of battery life and the ability to use the unit on its own or connect it to an external display or projector.
The comparison with TrackMan 4 was almost inevitable.
That was precisely the starting point of our original article. Handicap Golf put both devices side by side and hit nine shots: three with a 7-iron, three with a sand wedge and three with a driver. Some of the numbers were close enough to raise an enticing question: had Garmin managed to deliver some of TrackMan’s performance at a much lower price?
With hindsight, nine shots clearly do not constitute a sample large enough to establish the overall accuracy of a launch monitor. Handicap Golf, a channel specialising in golf tests and content, was providing a useful comparison rather than a scientific protocol. Nor should TrackMan automatically be regarded as absolute truth, with every different reading assumed to be wrong.
More importantly, discussing the “accuracy” of a launch monitor without specifying which metric is being assessed — and for what purpose — oversimplifies the issue.
The comparisons published in the months following the R50’s launch produced a much more nuanced picture: very convincing on some ball data, less certain on some club measurements and arguably more interesting once it is no longer viewed simply as a cheaper TrackMan, but as a different type of product.
Ball speed, carry and spin: what the measurements actually tell us
The original Handicap Golf comparison immediately highlighted one characteristic that would subsequently appear in other tests: ball speed measured by the Garmin R50 was often extremely close to TrackMan 4.
On the second 7-iron shot, Garmin recorded 105.0 mph versus 105.1 mph on TrackMan. With the sand wedge, the R50 showed 70.9 mph compared with 70.8 mph on TrackMan. Another driver shot produced 148.5 mph on Garmin against 149 mph on TrackMan.
Nine shots proved nothing by themselves. But they provided an initial indication.
In early 2025, Carl’s Place began a more structured comparison between the Garmin R50 and TrackMan 4. Wisconsin’s winter conditions initially forced the testers indoors, where Titleist RCT balls were among those used.
With the driver, the R50 measured an average ball speed of 146.6 mph (235.9 km/h) compared with 146.4 mph (235.6 km/h) on TrackMan. Carl’s Place calculated an average discrepancy of just 0.82%. With a 6-iron, the difference in ball speed was 0.72%. With a pitching wedge, it fell to 0.15%.
On ball speed at least, the different tests therefore tell a broadly consistent story.
Carry distance requires more caution.
With the driver, Carl’s Place recorded 218.4 yards on the R50 compared with 226 yards on TrackMan, approximately 199.7 versus 206.7 metres. The reported discrepancy was 4.01%. With the 6-iron, Garmin showed 175.5 yards compared with 181 yards, approximately 160.5 versus 165.5 metres, a difference of 3.14%. With the pitching wedge, the figures were considerably closer: 126.41 versus 128.5 yards, approximately 115.6 versus 117.5 metres, a difference of 1.65%.
Spin produced a similar picture. With the driver, the testers calculated an average difference of 7.27%, although they noted that one particularly divergent reading significantly affected the average. The R50 also tended to report slightly more driver spin than TrackMan in this particular series. The average difference dropped to 1.18% with the 6-iron and just 0.79% with the pitching wedge.
But it is important to understand what this experiment actually measures.
It establishes how closely two instruments agree or disagree. It does not automatically establish which one is correct.
TrackMan 4 relies on radar technology, while the R50 is a photometric system that observes the ball and club through three high-speed cameras. Comparing the two is extremely useful. Treating TrackMan by definition as a perfect measurement of physical reality is less so.
That is why the second part of the Carl’s Place test is arguably more interesting.
The testers took the R50 outdoors and compared Garmin’s reported carry distances with the carry distances actually observed.
With the driver, the average difference was 6.9 yards, or 3.4%. Some shots were within one yard of the observed distance, while others produced considerably larger errors. The biggest discrepancy was 34 yards, followed by other notable differences of 27, 16 and 12 yards.
With the 6-iron, the average difference was 5.5 yards, or 3.7%. The pitching wedge proved more problematic, particularly when its higher trajectories were exposed to gusting wind. Across all three clubs, Carl’s Place ultimately calculated an average difference of 3.72% between the R50’s carry figures and the distances observed outdoors.
Another finding deserves attention. Beyond distance alone, Carl’s Place reported that the starting direction and general shot shape displayed by the R50 corresponded well with what was actually seen in flight.
For an amateur who is primarily interested in dispersion and shot shape rather than differences of a few hundred revolutions per minute, that consistency matters.
The outdoor comparison was not a laboratory experiment either. The testers themselves noted the influence of the wind, particularly on higher shots. But it provided something missing from a simple R50-versus-TrackMan comparison: a check against the actual flight of the golf ball.
There is also a commercial context worth noting. Carl’s Place sells golf simulator equipment, including Garmin products. Its test is detailed and useful, but it comes from a company that also operates in the market being assessed.
Even with that caveat, the results illustrate something rather different from the implied promise of some of the earliest launch videos: the R50 can be exceptionally close on one shot and noticeably less so on another.
For an amateur trying to establish whether a 6-iron carries roughly 160 or 165 metres, the device may comfortably meet the requirement. For a professional attempting to determine whether a shaft change has produced precisely three additional metres of carry, the required tolerance is very different.
Club data remains the main area of caution
The earliest concerns surrounding the R50 related less to the ball than to the club.
In the Handicap Golf comparison, some measurements were almost identical. On one 7-iron, for example, clubface angle was measured at 4.9 degrees left by Garmin and 5 degrees left by TrackMan.
Other comparisons were far less reassuring. On one sand wedge, face-to-path was reported as 3 degrees left by the R50 and 10 degrees right by TrackMan. Attack angle also differed by several degrees on a number of shots.
Again, three shots with each club cannot establish a reliable trend.
One of the earliest detailed R50 reviews, published on 2 January 2025 by Matt Saternus of Plugged In Golf, raised a similar concern after comparing the Garmin with a Foresight GCQuad. Ball data was reported to align very closely with the GCQuad, while some club measurements proved less convincing.
Despite using the reflective stickers requested by Garmin, Saternus reported that some shots produced no club data and that other measurements differed noticeably from those recorded by the GCQuad.
Attack angle is particularly worth watching. In the comments beneath the review, one R50 owner reported differences of two to four degrees compared with TrackMan 4. One example involved a 7-iron reading of around -4 degrees on TrackMan compared with -7.5 degrees or more on Garmin.
That is one user’s experience rather than a controlled test. However, Saternus replied that he too had seen more extreme attack-angle values among the issues he encountered with the R50’s club data.
Plugged In Golf also uses affiliate links, another point worth noting when considering the source, although it does not in itself invalidate the observations made in the review.
For golfers, the distinction between ball and club data is far from academic.
A three-metre difference on a 180-metre carry is around 1.7%. That may be perfectly acceptable for someone building a general distance chart for the clubs in their bag.
A difference of two or three degrees in attack angle can lead to a substantially different interpretation of the swing, particularly during a fitting session or when working on technique.
Simply saying that the Garmin R50 is “accurate” is therefore not accurate enough.
The real questions are: accurate for which metric, how repeatable is that measurement and what decision are you trying to make with it?
One important caveat: the accuracy tests used older software
This is probably the most important point to add to our original analysis.
The principal measurements discussed above are not recent. Plugged In Golf published its indoor review on 2 January 2025. Carl’s Place initially worked indoors because of the Wisconsin winter, with published screenshots showing sessions dated 14 April 2025 indoors and 29 May 2025 outdoors.
In other words, none of these comparisons measures the Garmin R50 running the software available in September 2026.
Garmin has since released System Software 5.0.0, alongside GLM 4.3.0, with the update now available to all R50 users. In addition to new features, Garmin lists bug fixes and performance improvements.
Changes to the GLM software can potentially affect data processing and calculations associated with ball flight. It would therefore be unwise to assume that every discrepancy observed in 2024 or 2025 would be reproduced in exactly the same way today.
To our knowledge, no sufficiently documented comparative test has yet repeated these measurements using System Software 5.0.0 and GLM 4.3.0.
That leaves an important question unanswered: has Garmin simply expanded the user experience since launch, or has it also improved the consistency of some measurements?
A new comparison is needed to answer that.
The R50 of September 2026 is a more complete product
While the hardware remains fundamentally the same, its software environment has developed considerably.
Garmin already took an unusual approach in 2024 by turning the launch monitor itself into a simulator terminal. The 10-inch touchscreen can display data, impact videos and Home Tee Hero directly on the unit. It can also be connected to an external display or projector, while Garmin claims up to four hours of battery life.
Version 5.0.0 now pushes the training side considerably further.
The new Bag Mapping feature allows golfers to measure and track the average distance produced by each club. Garmin has also introduced dedicated distance-control and trajectory views, along with the ability to set a target distance on the driving range. The aerial range view and general practice experience have also been revised.
Home Tee Hero has evolved as well. Golfers can now chip when on the green or putt when close to it, customise auto-putt distances and move their position on the tee. Garmin has added forward tees, Match Play, Skins and Stableford formats, while multiplayer now supports up to eight players. The update also adds new club categories including Approach Wedge, Approach Wedge Hybrid and Mini Driver.
None of these features proves that the three cameras measure a golf ball more accurately than they did in 2024. They demonstrate something else: the value of a modern launch monitor no longer depends solely on its sensors. It also depends on its software, interface and the manufacturer’s willingness to continue developing the product after launch.
Two years on, that aspect works in the R50’s favour.
The R50’s real advantage may not be replacing TrackMan
This is ultimately the biggest change in our assessment since the product launched.
The original question — “can you get a TrackMan for much less money?” — was appealing, but probably the wrong one.
A fitting centre, golf coach or professional facility is not simply buying a device capable of displaying ball speed and carry. It is buying a working platform, a software ecosystem and a set of analytical tools where accuracy — and particularly repeatability — may be required to support decisions based on very small changes.
A private golfer may have an entirely different brief.
With the R50, the golfer can place the device beside the hitting area, switch it on and immediately have a screen, a practice environment, measurement data and a simulation platform. If a larger experience is required, an external display can be connected.
That autonomy may be one of the product’s most significant innovations.
It comes at a price. Garmin launched the R50 in Europe at around the €5,000 level, while full access to Home Tee Hero requires an active Garmin Golf membership. In France, Garmin currently lists its Premium membership at €9.99 per month or €99.99 per year.
At an unchanged annual price, five years of membership would therefore add roughly €500.
But considering only the cost of the launch monitor is equally misleading. The integrated screen and software may remove the need to buy equipment required by some competing solutions. Conversely, anyone wanting to build a full projected simulator will still need a suitable hitting mat, impact screen or net, projector and enough space to install everything safely.
That raises another interesting question: with a total budget of €5,000 to €6,000, is it better to buy an R50 or spend less on the launch monitor and invest more heavily in the simulator environment itself?
That deserves a separate investigation.
Two years on, the promise is easier to define
The Garmin Approach R50 has not made TrackMan 4 obsolete. Nor does the available evidence allow us to claim that it systematically delivers equivalent accuracy for a much lower price.
But the available tests do allow several conclusions to emerge.
Comparisons carried out in 2024 and 2025 show remarkably close ball-speed readings and generally consistent results across several other ball metrics. Carry and spin can show greater differences. Club data deserves more caution, particularly attack angle in the tests that examined it closely.
Carl’s Place’s outdoor work adds a particularly useful perspective. When compared not simply with TrackMan but with observed carry distances, the R50 finished the test with an average discrepancy of 3.72% across the three clubs used. Windy conditions and several substantial individual errors prevent this from being treated as a metrological validation, but it does bring the experiment closer to real-world golf.
One uncertainty remains in September 2026: the principal accuracy comparisons were conducted using earlier software versions. A new test using System Software 5.0.0 and GLM 4.3.0 is needed to establish whether some of the discrepancies seen in 2024 and 2025 remain today.
For a clubfitter or coach making decisions based on very small changes in club path, face angle or attack angle, that uncertainty matters.
For a private golfer looking to map club distances, work on shot shapes, analyse ball striking and quickly create a complete simulation environment, the requirements are different.
And that is probably where the R50 has aged better than the earliest comparisons suggested.
In 2024, Garmin appeared to be offering a device designed to approach professional launch-monitor performance for substantially less money. Two years later, the R50’s strongest argument appears to lie elsewhere: it combines a high-end photometric launch monitor, a standalone analysis console and a portable golf simulator in a single device.
The revolution may not have been about measuring exactly like TrackMan.
It may have been about reducing how much equipment you need around a launch monitor before you can really make use of it.
And on that measure, the Garmin Approach R50 looks more relevant today than it did at launch.
