Rory McIlroy – 4 time Major Winner

"I travel everywhere with a TrackMan. I think it's a very valuable piece of equipment for the top guys.

In the past I used it more for tracking the ball and numbers such as ball speed, launch angle, spin rate and that sort of stuff, or maybe doing some wedge distance control.

But in about August last year we started to look at numbers like attack angle, path and club direction to see if what I was feeling or what we were seeing was actually happening.

Sometimes TrackMan can tell you things that the eye can't see and that makes it a really useful tool.

If you go on any PGA Tour range, there's at least 10 or 15 guys that have their TrackMan behind them, analysing their shots and swings."
