RCT Golf Balls vs Metallic Dots: What Your Radar Launch Monitor Needs Indoors

A radar launch monitor works out spin by watching the ball fly, and in a garage or spare room it gets only 2.4m to 3m of flight before the ball hits the screen. Titleist RCT balls and metallic dots both fix that, and the Rapsodo MLM2PRO has RPT balls of its own. Here's which one your launch monitor needs, what each costs per ball, and the units that need none of them.

Quick summary

Radar units read spin from the ball's flight, and indoors they get only 2.4m to 3m of it, so without help spin is the number that suffers.

Titleist Pro V1 RCT balls carry a radar-reflective mark under the cover and cost £70 a dozen from Titleist, against £52 for the standard Pro V1.

A metallic dot does the same job on a standard ball for about 4p: our 400-dot pack is £16.99, and FlightScope puts 100 in the box with the Mevo+ and Mevo Gen 2.

The Rapsodo MLM2PRO needs its own RPT balls, not RCT, to show spin at all, and it comes with them in the box.

Camera units such as the Uneekor EYE MINI LITE, Square Golf Omni and ProTee VX read the ball at impact and need no special or dotted ball.

Which ball or dot does your launch monitor need?

It depends on how the unit reads the ball. Radar units behind the ball want an RCT ball or a dot indoors, the Rapsodo MLM2PRO wants RPT, and camera units beside the ball or on the ceiling read the ball you already play.

Why do radar launch monitors struggle with spin indoors?

Because they measure the ball in flight, and indoors there's barely any flight to…
