Photometric vs radar launch monitors

The two ways a launch monitor reads your shot decide how much space it needs indoors. Here's the difference in plain terms — and which suits your room.

Last updated: June 2026 · See our methodology.

Short answer: photometric (camera, sits beside the ball) is the easier fit for tight indoor rooms; radar (tracks ball flight from behind) prefers more depth and shines in larger rooms and outdoors. The SkyTrak+ uses both.

How each one works

Radar (Doppler): sits behind the ball and tracks it through the air, measuring flight to derive speed, launch and spin. Because it watches the ball travel, it likes a little distance behind the ball and toward the screen.

Photometric (camera): sits beside the ball and takes high-speed images of the ball and clubface at impact, calculating the numbers from that moment. It needs almost no flight distance, which makes it the natural fit for shallow indoor rooms.

Which should you pick?

Accuracy isn't strictly "photometric vs radar" — top units of both types are excellent. Space and budget usually decide it for a home build.

FAQ

Is photometric or radar better for an indoor simulator?
Photometric is usually the easier indoor fit (sits beside the ball, minimal depth). Radar prefers more depth and excels in deeper rooms and outdoors.
Why does radar need more space?
It measures the ball in flight, so it needs distance behind and in front of the ball. Photometric reads impact from beside the ball.
Which units are which?
Radar: Garmin R10, Mevo+. Photometric: Bushnell Launch Pro, Foresight. SkyTrak+ does both.
