The first putting simulator that measures Arc-To-Face — the one number tour coaches actually look at. For players, and now for their coaches.
Putting is where strokes are won and lost, and yet it has been the last discipline to attract serious measurement. We set out to change that — building hardware and software that gives every golfer the same feedback a tour coach would give, without the coach needing to be in the room.
And when there is a coach in the room, PerfectLine Coach puts every player's real data on their screen. Everything we make is designed in Seoul and machined to tolerances that don't belong in consumer electronics. We ship in three days and stand behind every unit for three years.

The metric · Arc-To-Face
Square at impact, square to the arc. We resolve it from your stroke, in degrees, every frame.
"Arc-To-Face is the only stroke metric that has actually changed how I teach. Everything else was noise."
"I rolled a hundred putts a night for a month. My three-foot make rate went from 86 to 94 percent."
"The Air clips into my bag. Before a round, on the practice green, it tells me what my hands are doing today."
