What Is a Golf
Launch Monitor?

A golf launch monitor is a device that measures the physical parameters of your golf shot the instant the club strikes the ball. Using either radar or high-speed cameras (or both), it captures data points like ball speed, launch angle, spin rate, and carry distance — giving you objective numbers on what your ball actually did, rather than what it looked like.

Historically, launch monitors were six-figure teaching tools found only in high-end club fitting bays and PGA Tour trailers. Over the past five years, consumer units from Garmin, Rapsodo, and FlightScope have made the technology accessible from around $199.99 up to $2,500+. Today, a backyard golfer can access accuracy within a few percent of the $25,000 TrackMan units used on tour.

Radar-based units (like the Garmin R10 and FlightScope Mevo+) emit microwave radio waves toward the ball and measure how they bounce back. By analyzing the frequency shift of returning waves (the Doppler effect), the unit calculates ball speed and direction. As the ball flies, the radar tracks its trajectory and derives launch angle, carry distance, and apex height. Spin is typically estimated from ball flight characteristics rather than directly measured.

Camera-based units (like the Rapsodo MLM2Pro) use high-speed cameras to photograph the ball at or just after impact, capturing the ball's orientation relative to its spin axis. This gives directly-measured spin data rather than an estimate. Club path and face angle can also be captured from footage of the club at impact.

Multi-camera units (like the Square Golf Omni) take this further with four cameras covering the ball and club from multiple angles simultaneously, enabling measured spin and more complete club data without the tradeoffs of a single-camera setup.

Hybrid units (like the SkyTrak+) combine both approaches — cameras for spin and club data, radar for ball flight tracking — delivering high overall accuracy across all metrics.

Not every unit measures all of these. Budget radar monitors typically cover ball speed, carry distance, and launch angle. Club path, face angle, and directly-measured spin are features of mid-range and premium units. The number of metrics a device captures is usually listed in its spec sheet as "data points" — the Garmin R10 captures 14, for example, while the Square Golf Omni captures 17.

The main practical tradeoff: radar units are more portable and work reliably outdoors without any special setup, but their spin numbers are estimates derived from ball flight models rather than direct measurement. Camera units deliver measured spin — which matters for iron gapping and fitting — but typically require more careful positioning and are best suited to a dedicated indoor space.

Hybrid units (SkyTrak+, Bushnell Launch Pro) use both technologies to minimize each approach's weaknesses, which is a significant reason they sit at higher price points.

A launch monitor helps if you practice regularly and want objective feedback on what's changing. Whether a new swing change is actually increasing ball speed — or just feeling like it is — is exactly the kind of question a launch monitor answers definitively.

They're also the backbone of distance gapping. Most golfers overestimate their carry distances by 10–20 yards. A launch monitor gives you accurate carries for every club, which is directly useful on the course.

What they won't do: fix your swing on their own, tell you why you're hitting it sideways (you need a coach for that), or substitute for actual practice time. The data is only useful if you know what to do with it.
