Launch Monitor
A launch monitor is an electronic device that measures what happens to the golf ball and the club at the moment of impact, then reports the data as a set of numbers. It captures things the human eye can’t see in real time, such as how fast the ball is travelling, how much it’s spinning, and the exact angle it left the clubface.
What is a launch monitor?
The device itself is a small piece of equipment, usually about the size of a thick paperback book, that sits on the ground behind or beside a golfer, though some models mount overhead. The point is straightforward: a clubface meets a ball at speeds that can exceed 170 mph on tour, and that collision is far too fast to assess by feel or by watching the ball fly. A launch monitor gives the golfer objective numbers for every swing.
Golfers use that data in three places: practice sessions on their own, lessons with a coach, and equipment fittings. The same device might sit behind a tour pro on the range at the PGA Championship, in a teaching bay at a local club, and in a home garage attached to an impact screen. Trackman, the company most associated with the technology, was founded in 2003 in Denmark by golfers Klaus and Morten Eldrup-Jorgensen alongside radar engineer Fredrik Tuxen, and its devices first appeared on the PGA Tour in 2006 (source: Wikipedia, Trackman).
How a launch monitor works
There are two main types of launch monitors: radar-based units and camera-based (also called photometric) units.
Radar-based monitors, like Trackman and FlightScope, sit behind the golfer and use Doppler radar to track the ball as it flies. The system sends out radio waves that bounce off the moving ball, then measures the frequency change to calculate speed, direction, and trajectory (source: Hireko Golf). Because radar tracks the full ball flight, these units work well outdoors and produce what’s known as “open data”: readings that reflect what the ball actually did in real conditions, including any wind effect.
Camera-based monitors, like the Foresight GCQuad and Uneekor’s units, sit beside or just in front of the ball and capture high-speed images of the impact and the first few inches of ball flight. By comparing those frames, the system reads the ball’s dimple pattern to measure spin and launch angles directly (source: Foresight Sports). This produces “closed data”: precise readings of what the club did to the ball, without any downrange weather affecting the numbers. Camera systems tend to be more reliable indoors, where radar struggles for space.
Some premium units combine both. Trackman 4 pairs dual radars with an HD camera to capture more than 40 data points per swing (source: Trackman).
What a launch monitor measures
Most launch monitors track a core set of metrics that describe the shot. Basic units measure ball flight; premium units add detailed club data.
| Metric | What it measures | Available on |
| Ball speed | How fast the ball leaves the clubface, in mph | All units |
| Clubhead speed | How fast the club is moving at impact | All units |
| Launch angle | The vertical angle the ball leaves the face | All units |
| Spin rate | Ball rotation in revolutions per minute | Most units |
| Smash factor | Ball speed divided by club speed (impact efficiency) | Most units |
| Carry distance | How far the ball flies before first bounce | Most units |
| Total distance | Carry plus rollout | Most units |
| Spin axis | Tilt of the spin that creates draw or fade | Mid-range and up |
| Club path | Direction of clubhead movement at impact | Premium units |
| Attack angle | Vertical angle of clubhead approach | Premium units |
| Face angle | Where the clubface is pointing at impact | Premium units |
For reference, the average PGA Tour driver swing produces a ball speed of around 170-175 mph (source: PlayBetter, citing 2024 ShotLink data) and a smash factor of about 1.49 (source: GolfLens, citing Trackman amateur averages and Tour data). Most amateur male golfers produce ball speeds in the 130-145 mph range with a smash factor between 1.42 and 1.48.
Launch monitor vs. golf simulator
These two terms are often used interchangeably, but they describe different things.
A launch monitor is the measuring device. It produces data. A golf simulator is a full setup that uses a launch monitor as one of its components, along with an impact screen, projector, hitting mat, software, and an enclosure that lets the player hit real shots indoors and see them rendered on a virtual course.
| Launch monitor | Golf simulator | |
| What it is | A data-capture device | A full indoor golf setup |
| Components | The unit itself | Screen, projector, mat, computer, launch monitor, enclosure |
| Primary use | Measuring shot data | Playing virtual rounds and practising indoors |
| Portability | Often portable | Fixed installation |
| Typical cost | $200 to $25,000+ | $5,000 to $100,000+ |
| Space needed | Minimal | Roughly 10 ft x 10 ft x 9 ft and up |
In short, every golf simulator contains a launch monitor, but a launch monitor on its own is not a simulator. A golfer can use a Garmin R10 at the driving range to track yardages and never plug it into a simulator. Plug that same unit into an impact screen, a projector, and the Garmin Golf software, and the launch monitor becomes the engine of a simulator.
Who uses launch monitors and why
Launch monitors are used by golfers at every level of the game.
On the PGA Tour, Trackman holds the official tracking partnership and has done so since 2006. In August 2025, the Tour and Trackman renewed the agreement through 2030 (source: PGA Tour press release). Trackman alone reports 1,000+ tour players and 15,000+ teaching professionals among its users.
Coaches use launch monitors during lessons to give students objective feedback rather than relying on the naked eye. Golf Digest Top 50 teacher Martin Hall has described the GCQuad as putting every coaching decision “on trial” because the data immediately shows whether a swing change is working (source: Golf Digest).
Club fitters depend on the technology to match clubs to a golfer’s swing. The Foresight GCQuad is widely used in tour-level club-fitting because of its direct, camera-based measurement of club face position at impact.
Amateur golfers were largely shut out of this market until 2021, when the Garmin Approach R10 launched under $1,000 and opened the door for home use. Today, the consumer market spans entry-level brands like Shot Scope (around $200), Garmin, Rapsodo, Voice Caddie, and SkyTrak. Premium home units like the Garmin Approach R50 sit near $5,000, and tour-level systems like Trackman 4 cost $25,495 (source: Trackman official FAQ).
Related Golf Terms
- Lateral relief — A free or penalty drop taken to the side of a hazard or obstruction.
- Lag putt — A long putt intended to get the ball close to the hole rather than in it.
- Launch angle — The angle at which the ball leaves the clubface after impact.
- Lateral hazard — A water hazard running alongside the line of play, marked with red stakes.
- Lag — Maintaining the angle between the club shaft and the lead arm during the downswing.
Frequently Asked Questions
How much does a launch monitor cost?
Prices range from about $200 for entry-level units like the Shot Scope LM1 up to $25,000+ for tour-level systems like Trackman 4. A capable home unit sits in the $500-$1,500 range.
Can a launch monitor be used indoors?
Yes, but performance varies by type. Camera-based units work well indoors. Radar-based units need enough ball flight to gather data and may struggle in tight spaces; most need at least 8-10 feet between the ball and the impact screen.
How accurate are launch monitors?
Tour-level units like Trackman 4 are accurate within 1-2% of the true value on most metrics. Affordable units like the Rapsodo MLM2 Pro have been described by reviewers as surprisingly close to Trackman on carry distances in side-by-side testing (source: Breaking Eighty), though spin data on budget units is less reliable than premium units.
Do you need special golf balls?
Some launch monitors require golf balls with printed dots or markers to track spin (older Rapsodo and SkyTrak units, for example). Most radar units and high-end camera units work with any ball.
Are launch monitors worth it for amateur golfers?
That depends on how someone practises. For golfers who already attend the range regularly, a launch monitor gives accurate carry distances for each club and removes the guesswork from gapping. For casual players who rarely practise, the data may sit unused.
