How Much Room Does the Blue Tees Rainmaker Need Indoors?
Published
Blue Tees currently tells indoor Rainmaker users to place the unit 5 feet directly behind the ball and leave at least 10 feet between the ball and the net or impact screen. That puts the launch monitor about 15 feet from the target before you add screen clearance. Because Rainmaker uses Doppler radar, the device may be small, but the tracking lane is not.
The Rainmaker needs room behind and in front of the ball
Rainmaker is a rear-mounted radar launch monitor. Blue Tees says to set it exactly 5 feet behind the ball, level with the hitting surface, and aimed straight down the target line.
For indoor use, the company recommends at least 10 feet of open ball flight between the ball and the net or impact screen. If the screen itself needs space behind it, add that separately when you calculate the room depth.
A 15-foot monitor-to-screen layout is the starting point
Five feet behind the ball plus ten feet in front gives you about 15 feet from Rainmaker to the screen. A room that is exactly 15 feet deep may still be too short once the enclosure, screen movement, golfer, and any walkway behind the launch monitor are included.
Mark the screen, ball, and launch-monitor positions on the floor before you buy the rest of the simulator. It is much easier to discover a depth problem with tape than after the enclosure arrives.
Indoor radar can be sensitive to the room around it
Blue Tees warns that fans, HVAC airflow, and large metal objects near the unit can interfere with radar readings. Garages deserve particular attention because they often contain metal shelving, door hardware, appliances, tools, and vehicles.
If the numbers look erratic, recheck position, level, alignment, firmware, and the surrounding environment before assuming the launch monitor is defective.
Rainmaker can grow into a full simulator
Rainmaker works as a stand-alone launch monitor with a 4.3-inch built-in display. Blue Tees also lists GSPro and E6 as simulator platforms, and its manual says you need your own subscription with those providers. Blue Tees announced in September 2026 that the E6 integration is live on Windows PC, with the license bought from E6 directly.
The software does not change the radar geometry. You still need the same physical tracking space even after a projector and impact screen are added.
If the room is short, compare tracking technologies
This is the tradeoff with rear radar: compact hardware can demand a long room. A camera system beside the ball or an overhead launch monitor may fit a shorter space because it does not reserve several feet behind the golfer for tracking.
