Radar vs Photometric Launch Monitors: Which Works Best Indoors?
Quick summary· AI-generated
The article challenges the oversimplified advice that photometric is always best indoors and radar is always best outdoors. It explains the technical differences: radar uses doppler signals to track ball flight over distance (requiring more depth but offering portability), while photometric uses high-speed cameras to analyze impact in the first few frames (better for tight spaces but less portable). The guide provides decision trees for different scenarios — radar suits golfers who want indoor/outdoor flexibility and have room for ball flight; photometric suits space-constrained setups where consistency matters; ceiling-mounted systems work best for mixed-handed players or minimalist room designs.
Excerpt from GolfBays - News
If you’re building an indoor golf setup, a standard piece of advice you’ll hear is that radar launch monitors are best for outdoors and photometric launch monitors are best for indoors.
Sure, there’s some truth in that. But there’s also a whole lot of missing context.
Because in reality, the best indoor setup isn’t just about choosing the best technology. It’s about choosing what matches your space, your tolerance for setup faff, and how much you care about things like spin accuracy, short game practice, and lefty/righty convenience.
In this guide, we break that down with real-world indoor constraints in mind.
A Quick Verdict For Indoor Golfers
Choose Radar if…
You want something portable you can use indoors and outdoors
You’ve got enough depth for a decent amount of ball flight
You’re willing to use RCT balls / metallic dots / patterned balls when needed for better indoor spin capture
Choose Photometric (camera-based) if…
Your space is tight and you want reliable readings without needing loads of depth for ball flight
You mainly care about indoor practice and sim play
You want readings to be consistent without regularly tweaking the setup
Choose a Ceiling-Mounted Setup if…
You’ve got mixed-handed players (or multiple users) and you don’t like the idea of moving kit around while playing
You want a clean floor area and a built-in feel
You want minimal interruption between shots
What Does Radar vs Photometric Mean?
Radar launch monitors (Doppler)
Radar launch monitors use Doppler radar to track the ball by sending out radio waves and reading the signal that bounces back. From that return signal, the unit calculates key ball-flight data - stats like launch direction, speed and trajectory - as the ball travels away from the hitting area.
Indoors, the trade-off is straightforward: the less ball flight you can provide, the less information the radar can capture before the ball hits the screen. That can lead to more estimation, especially on spin and shot shape, and less consistent results if your space or setup is tight.
With radar, space and setup matter more. But if you get the distances and alignment right it can be excellent.
Photometric launch monitors (camera-based)
Photometric launch monitors use high-speed cameras to capture the ball at (and immediately after) impact. Instead of tracking the ball over several metres of flight, they analyse what the cameras see in those first few frames - the ball’s launch direction, launch angle,…
