On course practice allows players to drop their ball on a given place on every single hole in the Trackman course library.

An an example, you can select the TCP Colorado course from the library, select the first hole and practice the tee shot as many times as you would like.

This allows you to go in and find iconic holes in the Trackman course library and practice them as long as you want to. Or it could also be a local course on the Trackman system at your club. You can go in and select a hole you struggling with in real time, and just practice it over and over again. 

Just like most other modules the data tiles are readily available to swap in and out. You are also able to change environmental and view settings just like you would be able to in course play!
