Looking for a GPS unit that I can load trails onto and track myself as I go along. Wanting to get out very early (ie: hiking in the dark) to points accessible only by foot. After trying this once last year and nearly missing sunrise because we got lost, I don't want to risk it again, and it's also a safety thing.
I've heard you can use your phone in airplane mode and it will use the GPS in the phone but I'm not sure how reliable or accurate this system is. If it is and I'm not up to date, what apps are good to get for CDN topos?
