As an old clock and compass, stick and pencil man, no reason why modern students shouldnt have a grasp of basic nav principles....with a map AND map reading, which seems to be a lost art
Great to have all that modern picture stuff but when it does a fizzer that other nav aid perspex comes in handy. You can use it to look at the terrain and relate it to the map..if you have one, since the screen went blank.
Have had a couple of times out in the wide brown yonder when ye olde GPS took time out....so back to basics, map, clock and compass..it still gets you home.
You wont feel too lost these days if you draw a magenta line on the paper map.
