How Much Room Does the Blue Tees Rainmaker Need Indoors?

Published · Updated

Blue Tees tells indoor Rainmaker users to put the unit 5 feet directly behind the ball and leave at least 10 feet between the ball and the net or impact screen. That's about 15 feet from launch monitor to target, before any screen clearance. The Rainmaker itself is small, but its Doppler radar still needs a long lane.

Behind the ball and in front of it

Rainmaker is a radar unit that sits behind the golfer. Blue Tees says to set it exactly 5 feet behind the ball, level with the hitting surface, and aimed straight down the target line.

Indoors, the company wants at least 10 feet of open ball flight between the ball and the net or impact screen. If the screen needs space behind it, that comes on top. Blue Tees Rainmaker setup.

Adding it up: 15 feet and more

Five plus ten puts the Rainmaker about 15 feet from the screen. A room that measures exactly 15 feet deep is probably still short once the enclosure, screen movement, the golfer, and a walkway behind the unit are counted.

Blue Tees' support guidance describes 10 to 14 feet of ball flight, or roughly 15 to 19 feet from the unit to the net, and says longer clubs benefit from extra flight distance. Rainmaker indoor space guidance.

Put the screen, ball, and radar positions on a floor plan before you buy anything else. A depth problem is cheap to find on paper and expensive once the enclosure is sitting in boxes in the garage.

Fans, ducts, and metal

Blue Tees warns that fans, HVAC airflow, and large metal objects near the unit can interfere with the radar. In a garage, look at metal shelving, door hardware, appliances, tools, and parked cars. Blue Tees setup and interference guidance.

When readings jump around, go back over position, level, alignment, firmware, and what's near the unit before you decide it's faulty.

GSPro and E6

Rainmaker can show shot data on its own 4.3-inch display. Blue Tees lists GSPro and E6 as simulator platforms. Rainmaker product details.

Blue Tees announced live E6 integration in September 2026: Rainmaker connects directly to a Windows PC via Bluetooth, without the LAUNCH app or a Rainmaker update. You buy the E6 license separately from E6. Check the selected software's hardware, PC, and license requirements before budgeting for course play. Blue Tees E6 integration announcement.

Adding a projector and impact screen doesn't shorten the radar lane. The 15 feet stay.

If 15 feet won't fit

That's the catch with rear radar: small hardware, long room. A camera unit beside the ball or an overhead launch monitor may fit a shorter space, since neither needs several feet behind the golfer.
