Photometric vs Radar Launch Monitors: Which Technology Is Better?

Launch monitors use one of two technologies: photometric cameras or Doppler radar. Each has genuine strengths and real weaknesses. Understanding the difference helps you choose the right monitor for your setup.

Photometric monitors use one or more high-speed cameras to photograph the ball at the moment of impact. The cameras capture ball markings and calculate spin rate, launch angle, and direction from the images. Examples: Bushnell Launch Pro, Foresight GC3, Uneekor EYE XO2, original SkyTrak.

Photometric advantages: Works in any lighting. Does not need the ball to travel far to get accurate data. Best accuracy for spin rate and launch angle. No metallic dots required on quality models.

Photometric disadvantages: Sensitive to ball position relative to the camera. Camera needs to be aligned precisely. Some models need careful setup to avoid shadow interference.

Radar monitors use Doppler radar to track the ball from launch through the beginning of flight. They measure speed and direction changes to calculate ball flight parameters. Examples: FlightScope Mevo+, Garmin R10, Voice Caddie SC4.

Radar advantages: Tracks ball further into flight, giving more accurate carry and total distance. Less sensitive to ball position. Good performance outdoors.

Radar disadvantages: Indoor radar monitors often need metallic dots on balls for accuracy. Needs more room between the hitting area and the net. Less accurate for spin data on cheaper models.

For a dedicated indoor setup: photometric is generally better. For outdoor use or mixed indoor/outdoor practice: radar is generally better. The Bushnell Launch Pro and SkyTrak+ solve this with a hybrid approach, combining both technologies.
