Watch the putting gate read real putts: ball speed, start line, and how far each putt would have rolled on a real green. These are real clips of real putts, not renders. Nothing here is sped up or edited to flatter the numbers.

Every putt gets a number

The gate reads the ball as it rolls through and the app fills in the distance it would have finished at, plus whether the start line was on. Nothing to set up between putts.

Ten courses, one mat

A run through every Sim 9 course, two at a time: The Gauntlet, Twilight Muni, Pineland, Autumn Glen, Midtown, Alpine, The Links, Sandpiper Isle, Cedar Ridge and Red Mesa. Same six feet of carpet behind all of them.

Two ways to see it

A six foot start-line drill, shown first as plain numbers and then on the 3D green. Same putt, same data, whichever you prefer to look at.

Where they come from

The founders batch is built and tested by the two of us. That is a print running in the basement the gates are made in.

How it got here

An early rig taped to a basement floor, and the same idea two years later reading a putt to a tenth of a foot.
