Rapsodo MLM2PRO: Room Requirements & Exact Placement

Rapsodo · Doppler radar + camera · typical price $700 · Updated June 2026

The Rapsodo MLM2PRO is a Doppler-radar unit that sits on the floor 6.5–8.5 ft behind the ball, looking down the line of flight. Add the recommended 8–10 ft of ball-to-screen distance and you arrive at the manufacturer's 15–18 ft room-depth recommendation (19.5 ft is a realistic working minimum with a buffer behind the unit). Keep metal pipes, frames, and rotating fans out of the radar's view — they add noise to spin readings.

Frequently asked questions

How far behind the ball does the Rapsodo MLM2PRO sit?

6.5 to 8.5 feet behind the ball, aligned with the target line, with the ball 8–10 feet from the impact screen.

What room size do I need for the Rapsodo MLM2PRO?

Plan on 15–18 feet of room depth: ball-to-screen plus the radar's space behind the ball. Ceiling and width depend on your height and swing — check the free room calculator.

Does the Rapsodo MLM2PRO work indoors?

Yes — it's designed for sim use at these distances, though indoor spin on short flights is calculated rather than fully measured on some shots.
