Funny you should say that......... I used to take my son out into the open countryside with a map and prismatic compass (they used SILVA compasses at their school Cadet Force until I gave them 6 prismatics 'on loan'/forever!) and use one of those while treaching him to read a map and read the land. He is better than me now. Mind you, that's not difficult! I used to be issued with a prismatic compass, kept it around my neck/in a pouch. It looked good of course, like a mickey mouse watch - but it was really just for the Sergeants to use who knew what they were doing

How many times have I seen people with the map laid out on the bonnet of the Landrover or alongside a 432........ with the compass open and sat on it!!!!!!
