The virtual unit is completely interactive meaning that the user can select any hole on the Medinah course to view. Then click on the colour hole map to show the distance both to that point and remaining distance to the green. Other interactive functions allow the position on the hole to be altered or to zoom in to the green or any part of the hole.
Golf fan Pete Stevens says "I've been using the virtual unit while following the opening holes of the first session on tv. It's great because I can 'walk the course' and get a real feel for each hole and get the distance information I want. Even from Tiger's wild drives on the opening holes."
