Best Golf Launch Monitors: How to Choose

It mostly comes down to how each unit measures the ball and how accurate the spin reading is. Entry-level models often estimate spin from a formula, while units with dual radar and camera (like the MLM2PRO) or a photometric system read real spin and are more accurate. Those are worth it if you're serious about reworking your swing or building an indoor sim.

Yes, but check the specs carefully. Some radar-based units need a fair amount of ball flight to read the shot, while models that list indoor support or an indoor mode pair much better with a hitting net.

It depends on the model. Basic data like carry and ball speed is free on many units, but some brands charge a subscription for course simulation or deeper analysis. Check before you buy that the features you actually want are in the free tier.
