What Does a Rapsodo MLM2PRO Need for an Indoor Golf Simulator?
Published · Updated
An indoor MLM2PRO setup needs at least 8 feet from ball to net, another 6.5 to 8.5 feet behind the ball for the unit, a compatible phone or tablet, and space to swing safely. Those distances total 14.5 to 16.5 feet before screen or net clearance. Measured spin requires RPT balls and Premium membership, and taller golfers may need the unit farther back to keep their swing video in frame.
MLM2PRO indoor distances at a glance
| Part of the setup | Distance | What it includes |
|---|---|---|
| Ball to net or screen | At least 8 feet | Ball-flight distance in front of the hitting position. |
| MLM2PRO to ball | 6.5 to 8.5 feet | Device placement behind the hitting position. |
| Device to net or screen | 14.5 to 16.5 feet | The two distances above, before adding screen or net clearance. |
The first two distances come from Rapsodo's indoor setup FAQ. Their sum isn't a complete room-depth requirement: include the screen maker's clearances, your swing, and any extra distance needed to frame a taller player's video.
Small unit, long lane
The MLM2PRO sits behind the golfer on the target line, and that's the first thing to know when you're working out whether it fits indoors.
Rapsodo's indoor setup FAQ specifies the ball-flight and device distances. Their sum is a 14.5- to 16.5-foot lane, not the complete room depth. An impact screen may want space behind it, and the golfer still needs somewhere comfortable to stand and swing.
Marking the floor
Mark the net or screen first, then measure 8 feet back to the ball. From the ball, mark the launch monitor 6.5 to 8.5 feet behind.
Club data changes things. Rapsodo's club-data setup guide calls for the ball to be 7.5 feet from the unit, inside the orange hitting-zone overlay, and the feature requires Premium membership. That sits inside the normal indoor range, but it's one more reason not to build around the shortest distance.
So a room sold as 15 feet deep can be tighter than it sounds once the screen, rear clearance, and the space around the golfer are in.
Tall players and the camera frame
Rapsodo's indoor setup FAQ notes that taller players may need to move the MLM2PRO farther back to keep the swing video in frame.
If video is part of why you want this unit, check the framing with practice swings from the tallest regular user before the mat or screen is fixed in place. A spot that frames one golfer well can cut off another's backswing or finish. With a temporary mat and some painter's tape, you'll catch that early. Once the room is built around one exact distance, it's a much bigger job.
RPT balls for spin
Rapsodo's ball FAQ says foam and plastic balls won't produce data. Regular golf balls can be used for other readings, but RPT balls are required to display measured spin rate and spin axis. These spin metrics also require MLM2PRO Premium membership.
If spin numbers matter to you, count those balls as an ongoing cost of the simulator.
Phone, TV, or projector
The MLM2PRO app runs on a compatible phone or tablet, so you can practice without a projector. For a bigger picture, Rapsodo lists HDMI output from a mobile device or AirPlay or screen mirroring to a smart TV in its display FAQ. Use an adapter that matches your device's port, and confirm that the device supports video output or the chosen mirroring method before buying a cable.
The projector math stays the same. Screen size, throw distance, mounting position, and swing clearance have to work on their own terms, whatever launch monitor you use.
Tight on depth?
Short garages, basements, and spare rooms deserve a full floor layout before you buy. The MLM2PRO is portable, but the lane it needs indoors isn't especially short.
Use the room size calculator to sketch your room, then check the layout against the MLM2PRO distances above and your screen or net instructions. The room plan doesn't replace the equipment's setup requirements.
If your depth is near the minimum, mark every distance and include the screen's rear clearance. Still cramped? A unit that sits beside the ball, such as Garmin's Approach R50, removes the rear device lane, though you still need room for the golfer and the swing.
