Does Your Launch Monitor Actually Read Putts?

This is the question the rest of the build depends on, and there is no general answer. We checked each manufacturer's own documentation rather than assuming devices behave alike.

Simulated Putting Is Not a Failure Mode

Every major simulator ships a way to not putt, and it is worth understanding before you conclude you need measured putting at all.

Trackman's auto-putting is explicitly probability-based. Its documentation describes "Auto - By HCP: Putt like your Trackman HCP. The game will auto-putt based on probability calculations tied to your HCP", and a Tour Pro mode using "probability calculations derived from PGA Tour statistics." GSPro offers Auto-Putt Fixed, Auto-Putt Random and Pick Your Putt. SkyTrak offers Auto Putt, Auto Fixed and Auto Two Putt. Garmin's devices add strokes when putting is off.

What "Stimp" Actually Means

Green speed gets quoted constantly in simulator marketing, usually without context. The term comes from a specific USGA measuring device and it means something narrower than most people assume.

The USGA describes the Stimpmeter as "a simple, accurate device manufactured by the USGA that allows one to make a standard measurement of, and place a numerical figure on, the speed of a putting green. It does so by measuring ball roll distance." It is an aluminium bar with a V-shaped groove, and "a ball will always be released and begin rolling when the Stimpmeter is raised to an angle of approximately 20 degrees with the putting surface."

The procedure matters as much as the number: three balls rolled in one direction, which "should come to rest not more than 8 inches apart", then three balls rolled back the other way, with the two distances averaged. A stimp figure is an average of two opposing directions, not a single roll.

How that compares with what turf makers publish

Here is the part worth knowing before you shop on green speed. Among the putting-surface manufacturers we reviewed, only one published a stimp figure at all — Fiberbuilt, which states in prose that its putting turf "runs at a 9 on the stimpmeter". The others published no green-speed number on the pages we checked, describing their surfaces qualitatively instead.

Where a figure does appear, it is marketing prose rather than a specification with a stated test method. Nobody we reviewed published the measurement conditions the USGA procedure calls for. So treat a published stimp number as a useful indication of intent, not as a tested, comparable figure.

The Insight: Match the Mat to the Software

If you take one practical thing from this guide, take this. The number that matters is not how fast your surface is. It is how closely your surface matches the green speed your software is simulating.

Trackman's own setup guidance for manual putting says it plainly: use a putting surface that mimics a real green, because "If the stimp of your mat differs too much from virtual golf, judging pace becomes more difficult." You are learning pace on a physical surface and being scored on a virtual one. If the two disagree, you are training a feel that does not transfer — inside the same round.

Most software exposes the setting so you can align them. GSPro has a "Stimp" setting that "will change the speed in which the greens will roll." E6 CONNECT goes further and states that "green speed is measured using USGA methods", and that certain pin positions become unavailable depending on the stimp rating so that "every pin position is compliant with USGA guidelines." SkyTrak's equivalent is qualitative — Slow, Normal, Fast, Lightning — with no number attached.

Combo Mat or Dedicated Green

The honest split: a combo mat is the right answer if you want to finish holes without leaving the hitting area. A dedicated green is the right answer if you want to actually practise putting, because roll distance and contour are what make practice useful and a combo strip gives you neither.

Space, and the Numbers That Constrain It

Putting is the one part of a simulator build with published distance requirements, so use them.

• Trackman 4, manual putting: at least 3 m / 10 ft from tee to screen, on a smooth, even surface.
• FlightScope Mevo+: 5 ft from sensor to tee, and a minimum recommended 8 ft of flat roll distance — and the sensor is closer than it would be for full shots, so plan to move it.
• Foresight GCQuad: about 22" from the hitting area, with an alignment stick used to set direction.

The recurring theme is flat roll distance. A green that is long enough to roll a realistic putt is a bigger constraint in most rooms than the hitting bay itself. Measure the flat run you actually have before choosing a surface.

Putting Surfaces at ProSimHQ

• Fiberbuilt Player Preferred Series Combo Golf Mat & Putting Green — hitting surface and putting surface in one footprint. Fiberbuilt states its putting turf runs at a 9 on the stimpmeter.
• Big Moss Golf The Augusta Putting Green — a dedicated green for players who want real roll distance.
• Big Moss Golf Country Club Putting Green — a larger dedicated surface.
• Big Moss Return Ramp — returns holed putts, which matters more than it sounds during a practice session.

The full range is in golf mats and turf. If you are still choosing a device, our launch monitor range is the place to start — and check its putting capability against the table above before you commit.

If you are costing the addition rather than the whole build, our golf simulator cost breakdown puts a putting surface in context against the rest of the room.

Common Mistakes

• Assuming your launch monitor reads putts. Several widely owned devices do not, and two popular families differ between models.
• Buying a green before measuring flat roll distance. It is the real constraint, and published requirements exist.
• Chasing the fastest surface. Matching your software's green-speed setting matters more, and the USGA itself advises against pushing speed for its own sake.
• Treating a published stimp figure as a tested spec. Where a number is published at all, it is usually prose without a stated method.
• Forgetting the sensor has to move. Some devices sit at a different distance for putting than for full shots.
• Expecting club data on putts. Some devices need markers on the putter face for it; others do not record it at all.
• Dismissing simulated putting. For short rooms and for round play, it is the sensible choice rather than a compromise.

ProSimHQ Editorial Note

ProSimHQ is an independent retailer of simulation equipment from multiple manufacturers. Device capabilities, software settings, pricing and specifications change — verify putting capability against your own device's current manual before purchasing a putting surface. Statements attributed to manufacturers and software publishers are their published claims. Where a device's documentation is silent on putting we have said so rather than inferred a capability or its absence, and where a manufacturer's own pages disagree we have flagged the conflict rather than picking an answer.
