Radar vs Photometric Launch Monitors: Which Fits Your Room?

Radar vs photometric is the first fork in choosing a golf launch monitor. Every launch monitor answers the same question — what did the ball (and club) do at impact? — but they answer it in fundamentally different ways. The technology you pick decides where the unit sits, how much room you need, whether it works outdoors, and often how much it costs.

This is a researched explainer based on manufacturer documentation (see how we research). We don’t rank accuracy here because we haven’t independently measured it.

The one-minute version

	Radar (Doppler)	Photometric (camera)	Hybrid (radar + camera)
How it measures	Tracks the ball’s motion with microwave radar	High-speed cameras photograph ball (and sometimes club) at impact	Radar tracking plus camera images
Typical placement	Behind the ball	Beside the ball (or overhead)	Behind the ball
Room depth	Needs space behind you + ball flight	Least depth	Like radar
Outdoors	Strong — reads full ball flight	Varies by model; many are indoor-focused	Generally yes
Lefty/righty	Usually no move needed	Unit usually moves sides	Usually no move needed

How radar launch monitors work

A Doppler radar unit sends out a microwave signal and reads the frequency shift as the ball (and club) move away from it. More ball flight gives it more data to work with. That’s why radar shines outdoors, where it can watch the ball for a long way, and why indoor setups specify minimum ball flight distances.

Published indoor requirements for popular behind-the-ball units:

Model	Behind the ball	Ball flight to net/screen	Source
Garmin Approach R10	6–8 ft	at least 8 ft	Garmin manual
Rapsodo MLM2PRO (hybrid)	5–8.5 ft	8 ft	Rapsodo
FlightScope Mevo Gen2 (hybrid)	7–9 ft	at least 8 ft	FlightScope

Spin indoors. With only 8 feet or so of flight, a radar has limited time to read spin. Manufacturers handle this differently. FlightScope states that indoors, “aluminum dots or Titleist RCT balls [are] required for accurate spin measurements” on the Mevo Gen2. Rapsodo’s measured spin depends on its RPT balls. Garmin doesn’t clearly publish which R10 metrics are measured versus calculated indoors; if spin precision matters to you, factor that in.

Strengths: portable, usually cheaper, excellent outdoors, no lefty/righty swap. Weaknesses: needs depth indoors; indoor spin may need marked balls or be estimated.

How photometric (camera) launch monitors work

Photometric units use high-speed cameras and controlled lighting to capture images of the ball — and on many models, the clubhead — in the first moments after impact. From those images the unit calculates ball speed, launch angles and spin directly, then the software models the rest of the flight.

Because the measurement happens at impact, a camera unit doesn’t need long ball flight. Most sit on the floor beside the ball, facing the golfer; some (like Uneekor’s overhead models) mount on the ceiling.

What that means for your room:

• Less depth. No unit behind you. SkyTrak, whose units sit beside the ball, notes on its planning page that other launch monitors “require up to 8’ behind the hitting area.”
• More width planning. The unit sits to the side, and it moves when a left-handed golfer hits.
• Positioning matters. Camera units have a defined hitting zone; the ball must be placed within it.

Strengths: compact room footprint, measures at impact (strong for indoor use), often measures club data. Weaknesses: higher prices at the top end, lefty/righty swap, many models are indoor-focused (check outdoor capability per model).

Hybrids: radar plus cameras

Hybrids try to get the best of both. The Rapsodo MLM2PRO pairs dual optical cameras with radar and publishes that 8 of its 15 metrics are measured. The FlightScope Mevo Gen2 uses what FlightScope calls Fusion Tracking (radar plus image processing) and lists 20 data parameters. Both still sit behind the ball, so for room planning, treat them like radar.

Price landscape (Oct 2026)

Model	Technology	About (Oct 2026)	Source
Garmin Approach R10	Radar	$499.99	Garmin
Rapsodo MLM2PRO	Hybrid	$599.99 (sale; $699.99 list)	Rapsodo
Square Golf HE	Photometric	$699	Square Golf
FlightScope Mevo Gen2	Hybrid	$1,299	FlightScope
Square Golf Omni	Photometric	$1,599	Rain or Shine Golf
SkyTrak ST MAX	Photometric	$1,695 (sale; $2,995 regular)	SkyTrak
Bushnell Launch Pro i	Photometric	$1,999.99	Shop Indoor Golf
Uneekor EYE MINI LITE	Photometric	$1,999	Uneekor
Bushnell Launch Pro	Photometric	$2,999.99	Bushnell

Note how photometric options start higher; the Square Golf HE is notable for bringing a camera unit under $1,000. Subscriptions also differ: for example, Shop Indoor Golf’s listing for the Bushnell Launch Pro i describes a Silver subscription at $199/year and Gold at $499/year, with club data included in the paid tiers.

Which should you choose?

Choose radar (or a radar-based hybrid) if:

• Your room has roughly 16+ ft of usable depth (see our room size guide).
• You want to take it to the range or practice outdoors.
• A lefty and righty share the setup.
• Budget is tight.

Choose photometric if:

• Depth is your constraint (basements, spare rooms).
• The sim will live indoors permanently.
• You want measured club data and are comfortable with the price (and subscription, for some models).

Choose a hybrid if:

• You want radar’s portability but more measured data or video, and you have the depth.

Indoor setup tips by type

Radar and hybrids (behind the ball):

• Measure and enter the exact unit-to-tee distance if the app asks. Garmin lists this first among its R10 setup steps.
• Keep the unit level, stable and aligned to the target line. Garmin’s R10 manual troubleshooting points to level, stable and in-line placement when the unit reports being tipped.
• Use marked balls if the manufacturer requires them for indoor spin (FlightScope: aluminum dots or Titleist RCT balls for the Mevo Gen2; Rapsodo: RPT balls for measured spin).
• Give the radar as much ball flight as the room allows, within the manufacturer’s range.

Photometric (beside the ball):

• Place the ball inside the unit’s marked hitting zone every time.
• Keep the unit’s view clear: no stray balls, tees or club covers between the cameras and the ball.
• Plan where the unit goes for left-handed golfers before building the bay.
• Consistent lighting helps cameras; follow the manufacturer’s guidance for your model.

Common misconceptions

“Cameras are always more accurate.” Accuracy depends on the specific model, setup and conditions. Manufacturers publish accuracy claims inconsistently, and we haven’t independently tested them, so we don’t rank by accuracy.

“Radar doesn’t work indoors.” Many radar units are designed for indoor use; they just need the published distances.

“Ceiling height depends on the launch monitor.” For floor units, no — it depends on your swing. Overhead units are the exception. See ceiling height by golfer height.

Bottom line

Pick the technology that fits your room first. Short room? Camera beside the ball. Deep room or outdoor use? Radar or hybrid behind the ball. Then compare price and subscription. Our best launch monitors under $1,000 is the place to start for budget picks.
