I used during many years severals GPSs devices, usually Garmin, like GPSMap 62s, Oregón, Dakota 20…all kind of GPS works FB, of course.
But the century XXI brings, IMO, better options (and free) for explore tracks and follow routes.
For example Mappy.cz, a free local Maps (no needs 4G) for android and iOS.
I use mainly WIKILOG (premium version 9,99 euros/year) It allows me follow routes better than any Garmin. Of course gives the option of send vía Internet a real position to our family.
