ProTee VX Overhead
25 data points, no markers, righty and lefty without moving the unit.
4K Birdie Package | ProTee VX overhead · Optoma 4K laser · 8 bay sizes
Grater Golf · Simulator PackagesA 4K home golf simulator package built around the ProTee VX overhead launch monitor, with the Birdie Bay in your choice of eight sizes. Dual high-speed cameras and A.I. watch the club and ball through impact from above, delivering 25 ball, club and flight data points in under 0.3 seconds, with no marked balls, no club stickers and nothing on the floor. The configurable 25" x 21" hitting zone lets right- and left-handed golfers play without moving the unit, and ProTee Labs practice software is included with no recurring ProTee fee. The Optoma ZK431ST-B projects true 4K UHD at 4,100 lumens from just a few feet away thanks to its 0.496:1 short-throw lens, the five-foot-deep Birdie Bay surrounds the impact screen with a full blackout wrapper, and Carl’s HotShot 4'x9' mat gives righties and lefties a centered, replaceable hitting surface. Starting at $9,678.61.

ProTee VX mounts to the room ceiling in front of the hitting area, ideally 9 to 10 ft above the hitting surface (10 ft optimal) and 3'4" to 3'7" from it, so choose a bay height that leaves room for the unit above it. Allow at least a foot of clearance around the bay width you pick, plus enough depth for the bay, the 4'x9' mat and a full swing. The ZK431ST-B’s 0.496:1 lens throws a 10 ft wide image from about 5 ft away and a 16 ft wide image from about 8 ft. Send us your room dimensions and ceiling height and we’ll confirm the layout before you order.
