Radar vs camera launch monitors

This is the first decision I'd make, before brand or budget. The type of launch monitor decides how much room you need and which numbers you can trust indoors.

How each one works

Radar (Doppler) units sit behind you on the target line and track the ball as it flies. They love open space, which is why they dominate the driving range. Indoors, the ball only flies 8–10 ft before hitting the screen, so some values (especially spin) are calculated or less reliable. The Garmin R10, Mevo Gen2, Full Swing KIT and Trackman 4 are radar units; the Rapsodo MLM2PRO adds cameras to its radar.

Camera (photometric) units sit beside the ball and photograph it at launch with high-speed cameras, measuring speed, launch and spin directly. They need no space behind you and handle short indoor rooms and chipping well. The Foresight GC3 and GCQuad, SkyTrak ST MAX, Garmin R50, Square Golf and Uneekor EYE MINI work this way.

Overhead units are cameras (or radar plus cameras) mounted on the ceiling: Trackman iO, Uneekor EYE XO2 and XR, Foresight Falcon.

Radar behind you

Garmin R10, Rapsodo MLM2PRO, Mevo Gen2, Full Swing KIT, Trackman 4. Cheapest way in and best outdoors, but they need the most depth: about 14–18 ft from the unit to the screen. They don't move for lefties.

SkyTrak ST MAX, Foresight GC3, Garmin R50, Square Golf, Uneekor EYE MINI. Best for short rooms and indoor short game. The unit moves to the other side for a left-handed golfer.

Trackman iO, Uneekor EYE XO2 and XR, Foresight Falcon. A clear floor and easy for both hands, but they need a 9.5–10 ft ceiling and a permanent install.

Side by side

	Radar behind you	Camera beside the ball	Overhead
Room depth	About 14–18 ft	About 15 ft	About 14–16 ft
Ceiling	Least critical	9–10 ft	9.5–10 ft for the mount
Indoor spin	Weakest; often calculated	Measured at launch	Measured
Outdoors	Best	Many work outdoors	Indoor only
Lefty + righty	No moving needed	Unit moves sides	No moving needed
Entry price	$499.99 (R10)	$699 (Square Golf)	$5,999 (EYE XR)

Room needs

Garmin puts the R10 6–8 ft behind the ball with at least 8 ft of ball flight; Rapsodo says a little over 14 ft in total; Full Swing puts the KIT 10 ft behind the ball. A camera unit beside the ball only needs the standard retailer room: about 1 ft behind the screen, 10 ft from screen to ball and room to swing behind you, so around 15 ft. Overhead units mount 9–10 ft above the hitting surface.

Indoor accuracy

In the independent studies I read, ball speed, club speed and carry agreed well across devices, while spin was the weakest number. A 2024 study of a radar unit (Mevo+) against Trackman 4 found driver spin off by 1,238 rpm on average indoors. That's the core reason I lean towards camera units for short indoor rooms. Full details: how accurate golf simulators are.

Which I'd choose

Short room or mostly indoor play: a camera unit beside the ball. Foresight GC3 if budget allows, SkyTrak ST MAX for value.
Deep garage and lots of range time: radar. Garmin R10 to start, Mevo Gen2 with no subscription.
Dedicated room, high ceiling, mixed-handed family: overhead, such as the Trackman iO or Uneekor EYE XO2.

One more consideration

Side-of-ball units have to be moved to the other side for a left-handed golfer. If lefties and righties share your bay, radar or overhead is easier.

Questions people ask

Is a radar or camera launch monitor better?

Neither is better everywhere. Radar is cheaper and best outdoors but needs room depth; cameras read spin at launch and suit short indoor rooms.

Are camera launch monitors more accurate indoors?

They measure spin directly at launch, which is where radar units struggle indoors. Studies found spin is the least reliable number on radar units in short rooms.

Do I need to move a camera launch monitor for left-handed golfers?

Yes for side-of-ball units like the GC3, SkyTrak and EYE MINI. Radar units behind the ball and overhead units don't move.
