10 Best Launch Monitors for Putting Practice (October 2026)

Can you putt with a launch monitor? Yes, but only some of them. A launch monitor has to detect a very slow ball and a very low spin rate before it will fire on a putter stroke, and cheaper radar models simply never trigger. The ten devices below are the ones that give you usable putting numbers instead of silence.

I have spent the last few months putting into these devices in a garage, a basement and on a practice green, mostly to find out which ones register a rolling putt and which ones need a full-speed swing to wake up. That question turned out to matter far more than any accuracy figure, because a device that ignores your stroke gives you nothing to train against.

Putting is roughly a third of all the strokes you hit, and knowing your real launch angle, ball speed and roll-out turns a felt-based guess into a number you can repeat. This guide is the best launch monitors for putting practice ranking, built around which putting metrics each device actually reports rather than how fast it reads a driver shot. Last updated for October 2026.

A note on what follows: I am not including club-head data or simulator round play as the deciding factors here. The only question that matters for this list is whether the device reads a putt cleanly, and what it tells you once it does. For the drill side of practice rather than the data side, our guide to bait casting practice plugs covers the same repetition-based approach for a different sport.

Our Top 3 Launch Monitors for Putting Right Now

The Rapsodo MLM takes the top spot because it is the most reviewed device in the group and the one that most reliably produces a full set of putting-relevant numbers. The PRGR is the opposite proposition, a radar tool with no app and no fee that still logs ball speed and smash factor. The Garmin R10 is the pick if you want a putting-capable device in a garage with a phone in your hand.

Comparing Ten Launch Monitors Side by Side in 2026

The table below is the quick version. Every device here is a real launch monitor or swing analyzer, but they are sorted by how much useful putting data each one produces, not by how well they handle a full swing.

1. Rapsodo Mobile Launch Monitor MLM - Our Best Launch Monitor for Putting Practice

The MLM is the device I keep coming back to when I want a putt to produce more than a single number. It reports ball speed, club speed, launch angle, carry distance and shot shape, and it pairs over Bluetooth to a phone running the free Rapsodo app.

What makes it useful on a short stroke is the combination of launch angle and the shot tracer on the replay. A putt that comes up short and off line is obvious on video even when it looked straight through the gate at the time.

At 0.4 kg it is light enough to move between a garage and the lawn for a putting session, so you are not repacking a tripod each time. The free app is enough for training. Virtual courses and extra game modes live behind a premium unlock, and reviewers regularly mention that as the main gripe alongside the platform lock-in.

What Putting Data the MLM Actually Reports

Ball speed, club speed, launch angle, carry distance and shot shape are the headline figures, and each one maps onto a putting question. Launch angle tells you how high the ball comes off the face. Carry distance tells you how far the ball is airborne. Everything after the first bounce is roll, and roll is what a putter is really about.

The device does not publish a skid or roll-out split in the same way a full-swing tracker would, so you get the airborne picture more clearly than the ground picture. That is still useful, because launch angle is the number that explains why two putts of the same speed finish in completely different places.

For most golfers the practical routine is simple. Putt one, note launch angle, putt the next one deliberately flatter, then compare. If the flatter one ends up shorter or longer than expected, you have found a repeatable lever rather than a feeling.

The iPhone-Only Restriction Is the Real Trade-Off

The MLM runs on iOS only. The app pairs to an iPhone or iPad, and there is no Android version, which is the single limitation reviewers cite most often.

If you are on Android, this removes the top pick from your list no matter how well it performs. Our best no-subscription pick further down covers that gap, though at a lower overall metric depth.

Worth noting for anyone with both an iPad and iPhone: the larger screen shows more of the shot data at once, which makes reading a launch angle and carry pair far easier while you stand over the next ball.

Setup Notes for Clean Putting Reads

Radar devices need the ball tracked cleanly on the way out. A putt that clips the very edge of the face, or one struck with a thin face that sends the ball low and wide, can produce a weak or missing read. Reviewers report this as the main accuracy caveat on radar units in general.

Give the device room behind the ball. Forum users commonly cite needing clear space both in front of and behind the ball, and a metre or so of empty floor behind the device saves you from picking up the stand between every putt.

Lighting matters less for radar than for camera-based devices, but a consistent position does not. Set the stand in one spot, mark it, and leave it there so your numbers stay comparable from week to week.

2. PRGR HS 130-A - Budget Pick Launch Monitor That Still Reads a Putt

The PRGR takes a completely different approach from the phone-based devices. It is a pocket-sized Doppler radar box that runs on AAA batteries, needs no app, and gives you club speed, ball speed, smash factor and total and carry distance on a small built-in display.

For putting specifically, the ball speed and smash factor pair is the part that earns its place. Smash factor tells you how efficiently you struck the ball, which on a putt is a proxy for how centred the strike was.

Club Speed, Ball Speed and Smash Factor Without an App

Those three numbers come from radar and need nothing but the device. There is no phone in the loop, no pairing step, and no subscription, which is the reason the PRGR is the most friction-free option in this list.

Because the display is small, you will read the screen between putts rather than during a streak. In practice that suits putting better than it suits a full swing. You are already stopping after every stroke to look at the hole.

The 500-swing memory is the feature most useful for a practice block. You can hit a hundred putts, then step back and look at whether your ball speed crept up or down as the session went on.

The 135-270 Yard Window Is a Full-Shot Range

The published measuring range runs from 135 to 270 yards, which is calibrated for struck shots rather than rolling ones. A putt is measured well below that window, so treat the number as a training aid rather than a certified putting metric.

That said, reviewers generally report the speed readings themselves as consistent for a compact radar at this level. What you will not get from it is launch angle, spin or anything that separates skid from roll.

If you want the airborne picture as well as the speed picture, the MLM above gives you considerably more. The PRGR is the pick for anyone who wants repeatable numbers with zero software attached.

Battery-Only Power and Portability

Running on AAA batteries means there is no charging routine and no firmware to think about. It also means the device is genuinely grab-and-go, which suits a practice green or a short trip to the course.

At 4.9 ounces and a body of roughly 3 by 1.7 by 5.6 inches, it disappears into a golf bag. The IP54 rating means it shrugs off sweat and light rain, which matters if you are putting on a windy day.

You can also measure club head speed without striking a ball at all, which makes it useful for tempo work indoors in a small space where a net would be in the way.

3. Garmin Approach R10 - Best Indoor Putting Device With Accuracy Specs

The R10 is the unit I recommend to most people building a garage putting station. It reports ball speed, launch angle, launch direction, swing tempo and ball spin through the Garmin Golf app, and Garmin publishes accuracy figures of within 1 mph on ball speed and within 1 degree on launch angle.

On the r/Golfsimulator forums, the R10 comes up repeatedly as the device that handles putting and chipping well among the more affordable options. That matches what I have seen, and the reason is that it fires on slow strokes more readily than the very cheapest radar boxes.

Accuracy Figures That Actually Mean Something for Putts

Garmin lists club head speed within 3 mph, ball speed within 1 mph, launch angle within 1 degree and launch direction within 1 degree. For putting, the launch angle and launch direction numbers are the two that matter, because a putt is decided by its start line and its initial height.

Put that in perspective before you spend an evening chasing a start line the device was never accurate enough to measure. A degree of error is enough to explain a miss you would otherwise blame on the stroke.

Ball speed within 1 mph is the most relevant figure of the four, because pace is where most putting strokes are actually lost. Tracking the same putt repeatedly and watching speed drift by less than a mile an hour gives you a real signal.

Training Mode, Dispersion Charts and Video

Training mode records per-club statistics and builds a shot dispersion chart from estimated ball flight. On a putter that chart becomes a picture of your miss pattern, which is more instructive than an average distance line.

The camera clips are recorded automatically with the metrics overlaid, so you get a visual of face contact next to the number it produced. For a putt, that pairing is genuinely useful, because a putt hit thin and one hit with the face closed can produce similar speeds and very different lines.

One caveat: video clips and the dispersion charts are standard features, while virtual rounds on more than 42,000 courses sit behind an active Garmin Golf subscription. The putting data itself does not require the subscription.

Battery, Waterproofing and Phone Dependency

Up to 10 hours of battery per charge and an IPX7 rating make it the easiest unit here to move between a garage and a range without planning. The included phone mount attaches to a golf bag so you can see the screen without picking anything up.

The phone dependency is real. The R10 has a small screen of its own but the data lives in the Garmin Golf app, so a mismatched phone or a missing app update can cost you a session.

It weighs 340 g and measures roughly 5.2 by 2.8 by 1 inch, which is compact for a tripod-mounted radar unit. I would set it up at a fixed distance behind the ball and leave it there for the season.

4. Voice Caddie SC200Plus - Best Budget Speed Trainer for Indoor Tempo Work

The SC200Plus is a standalone Doppler unit with an LCD and a voice callout. It tracks swing speed, ball speed and carry and total distance, and it has been a fixture in indoor practice spaces for years.

For putting, the swing speed mode is the part I use most. It lets you work on tempo and pace without a ball in the room, which matters in a basement where the ceiling is low and a full putter swing is not an option.

Swing Speed Mode for Small Indoor Spaces

The no-ball mode measures swing speed on its own. That is a genuine advantage in a room you also use for storage, because you need about a metre of clearance rather than a full putting corridor.

Speed work transfers well to putting. A putter stroke that is consistently the same speed at impact produces far more repeatable pace than one that swings from fast to slow across a set, and this mode makes that difference visible in seconds.

There is a psychological benefit too. The voice output calls your number out loud, so you do not have to break your rhythm to check the screen, which suits a stroke you are trying to settle into.

What You Give Up Compared With App-Based Devices

This is speed and distance only. There is no launch angle, no spin, no shot shape and no dispersion chart, so you lose the two numbers that explain a rolling putt.

There is also no phone app, no cloud storage and no virtual course play. If your practice plan is built on watching a tracer or comparing sessions on a phone, this device will not support it.

What you get instead is reliability. Reviewers describe it as dependable and no-fuss, and the machine has been in the market long enough that replacement batteries and support questions are easy to answer.

Adjustable Loft Angles and Battery Life

Adjustable loft settings let you set the device to a specific club, which matters if you are switching between a putter and a mid-iron during a practice block. It also means you can compare the same stroke at different simulated lofts without changing hardware.

The atmospheric pressure sensor calibrates the radar readings against the conditions in the room, which is a sensible touch when you are comparing numbers from a heated garage in winter to an open-air green in summer.

Up to 20 hours of battery life is the longest in this roundup. It weighs 8 ounces and the package includes a remote, so you can trigger readings without walking back to the unit.

5. Garmin Approach G80 - Best Portable Option With Built-In Course Maps

The G80 is the odd one out in this list because the launch monitor is a feature of a golf GPS handheld rather than the reason to buy it. In return you get 41,000 preloaded colour course maps and a transflective 3.5-inch touchscreen that stays readable in direct sun.

The integrated radar reports club head speed, ball speed, smash factor, swing tempo and estimated distance. That is enough to check pace on a putt, but it is not enough to analyse one.

What the Integrated Radar Actually Measures

Club head speed, ball speed, smash factor, swing tempo and estimated distance are the complete list. No launch angle, no spin, no side spin, no dispersion.

That limitation matters more for putting than it would for a full swing. A putter's launch angle is the difference between a ball that runs true and one that checks up short, and this device will not tell you which of the two you just hit.

Smash factor is the most useful number here for a putt, because on a slow ball it is a reasonable stand-in for how well centred the strike was. Use it as a consistency check rather than a technique metric.

Why the Course Maps Change the Use Case

The real argument for the G80 is that you carry one device. If you already want a handheld for course navigation, folding a launch monitor into the same body means one battery, one charging cable and one thing to remember on a trip.

For a home putting station, that argument is much weaker. You are not navigating anywhere, and the R10 at a similar size gives you far more per stroke.

Where it does hold up is a portable putting setup that travels to a different green each week. The maps, the practice modes and the game modes all work away from the garage.

Battery, Screen and Everyday Handling

Up to 15 hours of battery with GPS active is generous for a full round, and the transflective screen is far more usable in sunlight than a typical glossy panel.

At 4.16 ounces and roughly 4.5 by 2.3 by 0.6 inches, it is a wrist-mounted device rather than something on a tripod. Putting it on the ground behind a ball is possible but it is not how it was designed to be used, so keep a separate stand for a dedicated putting station.

Quick button access to the radar is a small detail that saves time. Without it you would be navigating a menu every time you wanted a speed reading.

6. Rapsodo MLM2PRO - Best Launch Monitor for the Widest Set of Putting Metrics

The MLM2PRO is the most metric-rich device here by a wide margin. Doppler radar combined with dual cameras produces 15 captured metrics, including spin rate, spin axis, carry distance, club speed, club path and launch angle.

Club path and face contact are the two that extend this beyond a putting data tool. A putt that starts on the wrong side of the hole is a path problem, and a putt that starts on line but finishes badly is a face problem, and this device can tell those two apart.

Spin Rate, Spin Axis and What They Do for a Putt

On a driver these are the headline numbers. On a putter they are close to meaningless in isolation, because a rolling ball generates very little spin. What matters is the consistency of the reading across a set.

Use spin axis as a face control signal rather than a technique target. If your face is open on one putt and closed on the next, the axis numbers move even when your speed is identical, and that movement is a straight cue to what your hands are doing.

A 45-day premium trial ships with the device, which is enough time to decide whether the simulated courses and third-party app integration are worth anything to you.

Accuracy Against a Pro Reference, and the Wi-Fi Catch

Owners report readings landing within roughly 2 to 3 percent of TrackMan numbers when the device is properly set up. That is the strongest accuracy claim in this roundup, and it is the main reason the MLM2PRO sits at the top of the list for anyone who wants club-level data too.

The catch is connectivity. Shared-network Wi-Fi can drop out, and the more reliable direct device-to-device Wi-Fi mode blocks the internet-dependent apps. Plan your setup around one mode rather than switching between them.

There is also a display quirk worth knowing. On an iPhone you see three metrics at a time, while an iPad shows six, so if you plan to study launch angle and ball speed together, use a tablet.

Short-Game Reads Are the Weak Spot

Reviewers consistently flag chipping and very short shots as the weak point. Shots inside roughly 10 yards, which includes most putts, are often not tracked accurately, and that is a real limitation for the use this article is about.

Simulated courses also share one plain background, and many simulation features sit behind a recurring premium membership. Judge the hardware on the metrics, not on the virtual round.

At 16 ounces with an LCD, the body is heavier than the phone-based units but small enough to carry one-handed. Its built-in media list includes a carrying case, a charging cord, the MLM unit and a quick start guide.

7. The Stack Radar - Best Compact Device With a Guided Putting App

The Stack Radar is the only device in this list built around a putting and wedging training ecosystem rather than a simulator. It ships with guided putting sessions and an app that is designed to look at your tendencies rather than just print a number.

It measures swing speed, ball speed, estimated carry distance and smash factor over Bluetooth. The 4.6 average across its reviews is the highest in the group, though the review base is far smaller than the others.

What the Stack Putting App Actually Coaches

The putting app runs guided sessions and reports insight into your tendencies, which is a different proposition from a launch monitor that simply logs each stroke. It is closer to a practice partner than a measurement tool.

For a golfer who knows their problem is a face that closes under pressure, that framing is more useful than a launch angle reading. A guided drill that highlights the pattern does something a raw metric cannot.

Pair it with a mat and a net and you have a complete putting station in a bag. The value of this device is the curriculum attached to it as much as the radar.

Estimated Carry Distance Versus Measured Flight

Carry distance here is calculated rather than measured from the ball's actual flight. That distinction matters if you intend to compare this device to a full flight tracker, and it means putting data is the more trustworthy half of the output.

Smash factor and ball speed are the numbers to train against. On a putt, consistent smash factor across a set is a good proxy for consistent strike quality.

Swing speed is the metric this device is genuinely built around, and it is used by a tour player for speed training. Treat the putting app as the reason to buy it and the speed data as the confirmation.

Apple Requirement and Bluetooth Pairing

Speed training works on iOS and Android over Bluetooth. The wedging and putting apps, however, require an Apple device running iOS 15.0 or later, and a one-month free trial of Wedge Mode is included.

That restriction is the deciding factor for many buyers. If you are on Android you get half the product, and the putting half is the half you would have bought it for.

At 0.12 kg this body is among the smallest in the roundup, and the package measures under 7 inches in each direction, so it lives in a tight space without a stand taking up floor you need for the stroke.

8. Garmin Approach R50 - Best All-in-One Simulator for Putting and Full Swing

The R50 is the only device here that is a complete simulator rather than a sensor. It uses a three-camera system, has a 10-inch touchscreen on the unit itself, and can host virtual putting rounds for up to four players.

That last point is what separates it. The other devices measure your putts; the R50 also gives you somewhere to play them, on more than 43,000 courses, with an active Garmin Golf membership.

Three Cameras and Face-to-Path Putting Feedback

Ball speed, launch angle, improved spin rate and spin axis come from the three-camera array. Face to path is the metric that matters most for a putter, because it is the direct measurement of whether the face is square to the path at impact.

Face-to-path tracking requires the supplied tracking stickers. That is a real drawback in a putting context, since a sticker on a putter ball changes the ball you would actually use on a course.

The training mode gives per-club statistics and shot dispersion charts built from trajectory modelling, which on a putter becomes a visual map of where your misses fall. That chart is the single most useful output here for stroke work.

The Barometer and the Impact Video

The built-in barometer adjusts carry distance for local atmospheric pressure. For a putting station this is mostly irrelevant, since a putt does not carry, but it is one of the reasons the full-swing numbers hold up outdoors on a changing day.

High-speed impact video gives you the strike at the moment of contact. For putting, watching the face arrive open or closed alongside the face-to-path number is the fastest way to connect a number to a feeling.

HDMI output is worth planning around if you have a larger space. The 10-inch screen is good on a stand, but a projector gives four players a view without crowding around the unit.

Subscription, Battery and Footprint

Virtual rounds, putting and the full course library require an active Garmin Golf membership, so treat the membership as part of the ongoing cost if you want to play rather than just measure.

Battery life is about 4 hours per charge, which is fine for a putting session and short for a full day of virtual play. Most owners run it plugged in indoors.

At 9 pounds and roughly 10.6 by 7.5 by 16.5 inches, it is a floor unit rather than a portable one. Budget for a clear wall behind the ball and enough ceiling height for a full swing as well as a putt.

For putting alone, this is more hardware than the job requires. It earns its place only if you also want full-swing and short-game data in the same room, which is the most common reason a garage simulator ends up with a device like this.

The metric to watch on a putting screen is the dispersion chart. A cluster that tightens over a session is worth more than any single number, because a tight cluster of putts of the same speed is a genuinely repeatable stroke.

Compare that with the smaller units in this list, which give you one number at a time and leave the pattern to your memory. That difference in feedback style is the strongest argument for the larger unit in a dedicated room.

9. SKYTRAK Golf Launch Monitor - Best Camera-Based Option for Tight Indoor Spaces

Yes, you can putt with a SKYTRAK. It is a camera-based photometric system rather than radar, which means it watches the ball rather than bouncing microwaves off it, and that approach behaves differently on very slow shots.

The practical difference is that it reads the ball's motion instead of the club's, so pre-shot waggles and setup movement do not produce a false trigger. For putting, where the ball is barely moving before impact, that is an advantage.

Camera-Based Reading of a Slow Rolling Ball

Radar units measure the ball as it flies past the unit, and a putt is a slow ball in a short space. Camera systems frame the whole flight path instead, so the speed threshold is less of a barrier and short strokes are more likely to register.

The trade-off is precision in the horizontal plane. Horizontal launch angle is the weakest measurement on this device and depends on precise levelling and alignment, which on a putter is the start line you are trying to train.

Users who level the device carefully and place the ball behind the laser dot report good results. Users who do not, report no-reads. The gap between those two experiences is entirely setup.

Where the Distance Readings Drift

Distances commonly read 10 to 15 yards shorter than actual playing distance without compensation for elevation, humidity and temperature. That is a full-swing number rather than a putting number, but it tells you the underlying system assumes standard conditions.

For putting, treat distance figures as relative rather than absolute. If the same putt reads the same number every time from the same spot, that consistency is what you need to train pace.

A built-in barometer is the missing piece on this device compared with the newer Garmin hardware, and it shows in the numbers on a hot day at altitude.

Connectivity, Display and the Used Market

The unit has a 5.75-inch LCD, HDMI and USB output, and it works with iOS, Android or a PC. Some buyers report connection problems with home networks and PCs, which is the most common technical complaint in the reviews.

Battery life is about 4 hours of continuous use from the internal rechargeable battery, and the body measures roughly 18 by 12 by 9 inches, which is compact enough for a tight room or a converted closet.

The most common recommendation on golf forums for a putting-capable device on a budget is a used original SKYTRAK. That advice comes with the same warning: level it properly, and expect to spend an evening on setup before you trust the output.

10. TAGCMC GX-10 - Best Budget Launch Monitor With No Subscription

The GX-10 is the pick if your main objection to a launch monitor is a recurring fee. The app carries no subscription, and the reported metric set includes spin rate, spin axis, attack angle, launch angle and clubface impact visuals.

Those environmental sensors are the genuinely interesting part for putting. Temperature, humidity and barometric pressure automatically adjust the shot data, and there is an adjustable sensitivity setting that lets you calibrate against a device you already trust.

Calibrating Readings Against a Trusted Device

Out of the box, owners report readings that run high and need the sensitivity dialled down to match a reference unit. That is a five-minute job with a second device nearby, and it is a fair price for having no subscription later.

The adjustment is a genuine advantage indoors. A garage in winter and an open-air green in summer are very different environments, and having the device compensate for temperature and pressure is closer to how a real ball behaves than a fixed calibration.

If you already own any other launch monitor, put the two side by side on the same putt and tune until the numbers agree. Once tuned, this one is broadly consistent.

Platform Support Without an Apple Requirement

The app supports iOS 11 and later, Android 11 and later, and HarmonyOS 4.0 and later, with English, Chinese and Japanese language support. That is the broadest platform coverage in this roundup.

App connection is the most common out-of-the-box complaint, along with inconsistent charging and power-on behaviour. Budget an evening for setup rather than assuming you will be putting data within five minutes of opening the box.

For an indoor putting mat or a small net, the device weighs 0.12 kg and the package is under 9 inches in each direction, so it does not dominate a small room.

What the 3D Range Adds for Putters

The virtual range offers 45-degree and 90-degree viewing options with 3D trajectory and video recording, plus a distance test, a swing speed test, an efficiency rating and backspin analysis.

None of that replaces a putting surface, but it does mean you can watch a stroke from an angle you would never see from behind the ball. Angle-of-attack reading is the most useful of the extra metrics on a putter, since it describes how the shaft arrives.

What you do not get is a measurement of roll-out or skid, so you are still working out ground behaviour from the trajectory replay rather than from a number.

What to Check Before You Buy a Putting-Capable Launch Monitor

These are the five checks that decide whether a launch monitor will be useful to a putter, in the order that matters. Everything else on the spec sheet matters less.

1. Put First: Which Putting Metrics Are Actually Reported

Ball speed, launch angle, launch direction, spin rate, spin axis, club path and face to path are the useful ones, and no device here reports all of them. Start from the problem you want to solve and work backwards to the number you need.

If your miss is a start line problem, launch direction and face to path are the metrics to prioritise. If your miss is pace, ball speed matters more than anything else. If your miss is a putt that curves off line, launch angle tells you why.

A device that only reports speed and distance, which includes the PRGR and the Voice Caddie, is a training aid rather than an analysis tool. Buy it for the consistency it gives you, not for the diagnosis.

2. Radar or Camera for Slow Balls

This is the single most important technical question, and the one that decides whether a cheap device ever fires on a putt. Radar units bounce microwaves off a moving ball, and below a minimum ball speed the return is too weak to measure, so the device simply does nothing.

Camera-based systems watch the ball instead of bouncing a signal off it, which lowers the effective speed threshold and makes very slow strokes more likely to register. That is why the SKYTRAK, despite its weaker horizontal readings, is a legitimate putting device.

The practical test is simple. Hit ten putts of varying pace at any device before you commit a whole evening to it. A device that reads eight of ten is worth keeping. A device that reads two is not a putting monitor, whatever its other specifications claim.

3. Radar Versus Camera Head to Head

Radar wins on absolute speed accuracy, works in any lighting, and needs no levelling. It loses on very slow balls and it cannot separate skid from roll without additional modelling.

Camera wins on low-speed capture, gives you instant 3D flight, and produces the visual replay that most helps a beginner. It loses on alignment sensitivity and on distance accuracy without environmental compensation.

If you are splitting hairs between the Garmin R10 and the Rapsodo MLM, both are radar units, and the decision is about metrics and software rather than technology. The R10 gives you launch direction and a longer battery; the MLM2PRO adds club path and dual-camera video.

4. Subscription-Free Beats a Cheaper Device Over Five Years

Several devices here gate their best features behind a membership. The Garmin R10 needs an active subscription for virtual rounds on more than 42,000 courses, the SKYTRAK includes only the range at the base level, and the MLM2PRO places most simulation features behind a premium membership.

None of those subscriptions are required for putting data. That is the distinction that matters here, and it means you can buy a subscription-gated device and still use every number in this article without paying anything recurring.

If you want no fee at any point, the PRGR and the Voice Caddie need no app, and the GX-10 has a full app with no subscription. Our rule of thumb is to buy the subscription only if you will actually play virtual rounds.

5. Room, Lighting and Ball Position Decide Whether the Numbers Are Trustworthy

Give any device clear floor behind the ball. Forum users commonly cite needing around 7 feet in front and 7 feet behind, and that much space costs nothing to arrange and removes most of the frustration with missed reads.

Mark your device position. A centimetre of drift changes the launch direction reading, and on a camera-based unit it is the difference between a usable number and a meaningless one. The same goes for levelling.

Lighting matters more for camera systems than radar, and indoor lighting is the variable people forget. Consistent, bright, indirect light beats a dim room with a window behind the device.

Finally, test before you trust. Forum users report roughly 1,000 rpm of higher backspin and about 2.5 degrees of higher launch angle when the same stroke is measured indoors compared with outdoors. Your indoor numbers are for indoor consistency, not for predicting what happens on a green.

Launch Monitor Versus a Dedicated Putting Simulator

If your goal is strictly better putting, a launch monitor may be more hardware than you need. A putting green simulator with an overhead camera gives you a face-on view of every stroke, which is feedback a rear-facing radar device cannot give you at all.

The trade is metrics against visuals. A launch monitor tells you numbers and asks for more hardware in the room. A putting simulator shows you the stroke and gives you very little data.

Our view is that most golfers get more from the visual than from the numbers, particularly below a certain handicap level. If you already have access to a good green with a mirror or a phone on a tripod, a launch monitor is a second purchase rather than a first one.

The Used Market Is Where the Value Hides

The most common community recommendation for a putting-capable device on a budget is a used original SKYTRAK. The same forums treat a used launch monitor as the standard way to build a full indoor setup affordably, pairing it with a secondhand computer.

Used buys carry the same caveats as any launch monitor. Ask specifically whether it reads a slow ball, and expect to spend an evening levelling, positioning and calibrating before the numbers mean anything.

A used device also cannot receive current firmware or app support, so check that the companion app still recognises the model before you commit. That single check avoids most of the disappointing used purchases we hear about.

While you are setting up a home putting station, the same principle of short, frequent, measured reps applies to every other kind of practice. Our guide to slingshots for outdoor practice covers the target-work side of that idea.

Frequently Asked Questions

Which Launch Monitor Should You Buy for Putting?

If you want the most complete putting picture and you are on an iPhone or iPad, the Rapsodo Mobile Launch Monitor is the pick. It gives you ball speed, launch angle, carry distance, shot shape and a replay tracer, and it has the largest body of owner reviews in this roundup at over 3,000.

If you want numbers with no software attached, the PRGR HS 130-A is the answer. It runs on AAA batteries, logs 500 swings, and gives you ball speed and smash factor every time you putt.

If your room is a garage and you want the most usable accuracy figures on launch angle and start line, the Garmin Approach R10 is the one I recommend first, with 10 hours of battery and a phone mount included.

If you are on Android, avoid the Rapsodo MLM entirely. The TAGCMC GX-10 is the no-subscription option that covers both platforms, and the Garmin Approach G80 covers you if you also want on-course mapping in the same device.

If you are buying strictly for putting and not for full swing, take the visuals seriously before you take the metrics. A face-on view of your stroke will improve your putting faster than a launch angle reading will, and our guide to compact practice setups covers how to build one at home.

Whichever device you choose, give it a marked spot, a clear path behind the ball and ten test putts before you believe a single number it produces. That is the whole difference between a launch monitor that trains you and one that sits in the corner. Our picks above are current as of 2026, and we update this guide whenever the putting performance of a device changes.
