I call that ‘navigating by sense of smell’.
I know of company commanders that will order their troops to leave their GPS back on post every so often to ensure they can navigate without GPS.
There are times when you just have to ignore the GPS. It won’t always take you were you want to go or by the way you desire.
We purchased a handheld GPS for our USMC Infantry son before his first run in the sandbox.
Later they issued him one,same model, he used his for all three trips.
Somewhere along the line his guys updated it.
