I spend a lot of time in the backcountry trekking, hiking, snowshoeing, and canoeing. Over the last couple years I have increasingly started using my iPhone for navigation using GaiaGPS and Avenza PDF Maps. My old phone, though unpowered for day to day life still functions great for navigation. On long trips I’ll bring this second phone as a backup map/gps which is smaller and lighter than the equivalent paper maps and navigation tools.
