The Fan Bay, Explained
A calm-air launch number and a real-world Tempe number are rarely the same shot. Our fan bay lets us measure the difference directly instead of guessing at a wind correction after the fact.
Dual-Trace Launch Capture
Two tracking units read every shot — one against still air inside the bay, a second pass against a set headwind or crosswind from the fan array — so ball speed, spin, and launch angle get compared across both conditions on the same swing.
Adjustable Fan Array
Wind speed and angle are dialed to match what a given hole or time of year in the Valley actually produces, rather than a single fixed setting used for every session regardless of what you're fitting for.
The Trajectory Window
The range of launch and spin combinations that hold their line in wind, not just the single number that flies farthest in calm air. We fit to the window, not the peak.
A Number That Only Holds Up Indoors Isn't Useful in Tempe
Afternoon wind through the Valley is common enough that a driver optimized purely for a still-air launch monitor reading can lose several yards of dispersion the moment real wind shows up on the course. Testing the same swing against both conditions is what lets us recommend a spin and launch combination that's still playable once the wind picks up, not just the one that looks best on a calm-day printout.
Two Numbers on Every Spec Sheet
Every written build spec lists both the still-air reading and the fan-bay reading side by side, so you can see exactly how much a given head-and-shaft combination is expected to hold up once wind enters the picture — not just a single idealized carry number.
