Your 7-iron flies 165 on the garage screen and 155 at the range on Saturday. So which number do you trust, and is the gadget worth the money if it can’t agree with the grass?
Here is the straight answer. A decent home simulator gets your ball speed almost exactly right and your carry within a few percent. The driver is where it drifts, and your garage is often a bigger cause of that than the box on the floor.
Short answer: Good consumer launch monitors land within about 1.5% to 6% of a TrackMan on carry, depending on the club. In a side-by-side test the Garmin R50 read ball speed within 1% and wedge carry within 1.65%, but driver carry came up 4.01% short. Expect wedges and mid-irons to match closely and the driver to wander by 5 to 10 yards.
The launch monitor accuracy chart nobody puts in one place
Brochures quote “within 2%” and leave it there. Independent tests tell a messier story, so here are the ones with real numbers, set side by side. The reference column matters: a TrackMan is the yardstick most testers use, and a rangefinder walk to the ball is the next best thing.
| Unit | Compared against | Wedge carry gap | Mid-iron carry gap | Driver carry gap |
|---|---|---|---|---|
| Garmin R50 | TrackMan 4, indoors | 1.65% | 3.14% (6-iron) | 4.01% |
| Rapsodo MLM2PRO | Measured carry, outdoors | 5.64% | 3.14% (6-iron) | 2.59% |
| SLX Hybrid Mini | TrackMan 4 | 0.3% | 2.3% (7-iron) | 5.9% |
| Swing Caddie SC4 Pro | TrackMan | Not tested | 2.1 yd avg (7-iron) | Not tested |
| SkyTrak (original) | TrackMan, range | Carry within 3%, total up to 6% off, worst with driver | ||

Ball speed is close to perfect, and that is the number that matters
Every simulator builds the flight from a handful of launch numbers. Ball speed is the big one, and the good units nail it.
In the R50 test, driver ball speed read 146.6 mph against TrackMan’s 146.4 mph. With the pitching wedge the gap was 0.15%. The SC4 Pro averaged within 1.8 mph of TrackMan over 50 shots with a 7-iron.
So when the carry number disagrees, the fault usually lies in spin or launch, not speed. That is good news, because it means the device is reading your strike honestly.
The rule: if ball speed matches the range and carry doesn’t, look at spin, launch and your room before you blame the hardware.
Why your driver reads short indoors
The driver is the club every test struggles with. The R50 read driver carry at 218.4 yards against TrackMan’s 226, a gap of about 7.6 yards. The SLX Mini missed driver carry by 5.9% while getting wedges within 0.3%.
Spin is the usual culprit. The R50 read driver spin 7.27% higher than TrackMan, and more spin on a drive means less carry. Club data without the supplied stickers was, in Carl’s words, “a lot less trustworthy”.
shots hit higher into the wind tended to come up short in the R50’s readings

Then there is you. Owners on the Golf Simulator Forum report indoor and outdoor carry splits of 10 to 15 yards with the same unit. One poster put the range side of it bluntly:
In short you are hitting what amounts to fliers on the range.

Others in that thread blame a cut-short follow-through in front of a net, or a mat that strikes differently from turf. The owner with the 10 to 15 yard gap simply took a full club less on the course.
The rule: treat your indoor driver number as a range, not a fact. If it is consistently off by the same amount, learn the offset and move on.
TrackMan vs SkyTrak: how big is the accuracy gap?
This is the comparison most buyers have in their head. The best evidence is a 2018 University of Ljubljana master’s thesis that set the two side by side across several golfers and clubs.
It found a systematic error in how that SkyTrak unit measured side angle, which feeds every number calculated from it. SkyTrak data came out slightly less accurate overall and noticeably worse for less skilled golfers and longer shots. When the author used each system’s data to sort good swings from bad, the TrackMan model hit 85.4% accuracy and the best SkyTrak model 75.0%.
The GolfWRX range comparison was kinder: carry within 3%, total distance up to 6% off, with the driver the worst. Both tests used the original SkyTrak, not the current ST MAX, so read them as the floor for the brand.
Worth knowing: camera units like SkyTrak see spin directly, while a radar-only unit such as the Garmin R10 measures ball speed, club speed, launch angle and direction, and calculates the rest. That is why cameras tend to win on spin indoors.
The rule: TrackMan stays the most accurate launch monitor in these tests, but a SkyTrak gets you within a few percent on carry for a fraction of the outlay.
Room size changes the answer more than the badge
Radar needs to see the ball fly. Garmin asks for a minimum of 15 feet for the R10, 7 behind the ball and 8 to the net, and Golf Insider UK’s R10 review found it needed about 10 feet to the net for consistent data. Indoors, that tester struggled to get shots captured at all with the suggested setup, then got clean reads once outside.
Camera units sit beside the ball and need far less room. Golfers Authority’s photometric vs radar guide puts photometric units at about 10 feet total against 16 to 21 feet for radar.
The rule: in a short garage, a camera unit will be more accurate than a better radar squeezed into too little space. Measure first with our guide to golf simulator room dimensions.
The units that earn their place
If you want the closest thing to TrackMan numbers without the TrackMan bill, the Garmin R50 is the one with a published test to back it: ball speed under 1% off and wedge carry within 1.65% of a TrackMan 4. It sits in the premium tier, around the same money as a Full Swing Kit.

The Garmin Approach R10 is the radar pick for a long garage or the range. Golf Insider found carry and total generally within 5 yards on wedges, with club path and face angle out by roughly 1.5 to 4 degrees.
The Garmin Approach R10 is not as accurate for tracking spin and lateral error.

Which one I would buy
- If you play twice a month and want winter practice in a short garage, buy the MLM2PRO and the RPT balls. Skip it if you won’t pay for its subscription.
- If you have 15 feet or more and want to take it to the range in summer, buy the R10. Skip it if fixing a slice is the point, because its face and path numbers aren’t sharp enough.
- If you are building a proper room and want numbers you can gap your irons with, buy the R50. Skip it if you already own a good radar and just want a screen.
Questions buyers ask
Is a golf simulator accurate enough to gap my irons?
For wedges and mid-irons, yes. The tests above put those clubs within roughly 1.5% to 3% on the better units, which is 3 to 5 yards on a 7-iron.
Why do I hit it further on the simulator than the range?
Often it is the range that lies. Range balls, fluffy lies and wind all move the outdoor number, and owners report 10 to 15 yard gaps with the same unit.
Can I trust the wedge numbers outdoors?
Less so. The MLM2PRO’s biggest miss in the Carl’s Place test was the pitching wedge, at 5.64%, which the tester put down to wind higher up.
Do I need special balls?
For measured spin on a Rapsodo, yes: Callaway RPT. Radar units like the R10 work with ordinary range balls.
The verdict
A good simulator is accurate enough to practise on and to gap every club from wedge to hybrid. It is not accurate enough to settle a driver argument to the yard, and nothing short of a TrackMan in a big room is. Pick the unit that suits your space, learn its offset, and trust the ball speed. Our best golf launch monitors for 2026 ranks the full field, and if you are still choosing between a full setup and a box on the floor, read golf simulator vs launch monitor first.
