Putting together a budget-friendly navigation kit for hiking and some weekend land-nav practice (nothing extreme). Phone GPS is fine until batteries die or you lose signal, so I’m looking for a dedicated GPS unit that won’t destroy my wallet.
Priorities: decent satellite lock under trees, long battery life on AAs, simple interface with waypoint/track logging, and rugged enough for rain and getting tossed in a pack. I don’t need fancy maps, but I’m open to them if it’s worth it. What are the best budget-friendly GPS units right now, and are used/refurb units a good idea?
