What is the point of teaching an innacurate method, when it can and does get people killed?
A 'general' direction, which can be out 30 degrees is not accurate enough to be teaching it.
It reminds me of the popular American myth still found in so called survival 'instructors' manuals over their in the states (in glorious colour photos) of using a condom for carrying water!
Thats has to be about the dumbest most useless modern ways of transporting water I could dream up, yet it's published for the world to see.
If you want to learn Nav, then learn it properly, and practise it, and you'll also laugh at ridiculous 'tips' like using an analogue whatch!!!!
