For a hundred years golfers have watched a ball sail offline and asked the sky "what happened?" — at GolfBox, Trackman IO just tells you.
Prologue
Every golfer has said them. You hit a snap hook into the trees and mumble "I think I came over the top." You slice one into the car park: "I think the face was open." You're guessing. And the scariest part is — you've probably been guessing the same way for ten years.
Here's the quiet revolution happening at GolfBox Bath and Bristol: Trackman IO has replaced "I think" with "I know." And when it comes to whether your ball draws, fades, hooks, or slices, you really only need to understand two numbers: your Club Delivery Path and your Club Face Angle at impact. This guide will teach you both — with a live interactive you can play with right now.
The entire shape of your ball flight — straight, draw, fade, hook, slice — comes down to the relationship between these two things:
Measured to a tenth of a degree. Is the club coming into the ball from inside (in-to-out, positive) or from outside (out-to-in, negative)? Trackman IO measures the exact arc and shows it to you from above — the same view we'll use below. The path decides where the ball ends up.
Also to a tenth of a degree. Is the face open (pointing right of target, positive) or closed (left of target, negative)? Dual high-speed cameras plus radar capture it at the precise instant of impact. The face decides where the ball starts.
Here's the whole story of ball flight in two sentences:
The ball starts where the face is pointing. It curves away from the path.
That's it. The difference between face and path — called face-to-path — decides the shape. Face matches path? Ball flies straight (in whatever direction they're both pointing). Face more closed than path? The ball curves left. Face more open than path? Ball curves right. Pick a shape and watch:
Club path and face are both aligned with the target. Face-to-path delta is zero. The ball starts at the target and never deviates. Beautiful. Rare. Mythical, even.
This is a top-down view — like looking straight down from the ceiling, the same angle Trackman IO uses for its club delivery graphic. The golfer is on the left. The ball is in the middle. The target line runs straight up the screen. Move the sliders and watch the club arc rotate through the ball, the face swivel, and the ball flight curve. You'll feel the physics in less than a minute.
The swing is a theory. The data is the truth. Trackman IO just finally lets you read it.
