Useful exercise – get deliberately lost.
Position yourself well away from CAS. Over the middle of Wales works, but the location has to be sensible.
Switch off your nav aids and do not look at any ground features or the compass for 10 min.
Apply the circle of uncertainty and try to get un lost
If you have not found yourself for the length of time it would take you to reach CAS less 20 min (from the known point at the start of the exercise), turn everything on and ask for help if needed.
This is surprisingly good fun and can be very hard if the vis is not too good.
Having “found” yourself, diverting to the nearest airfield without the tec on is also quite useful.

PS I have not done this for some time and intend to do so soon.
