Practical notes
Do I need a dedicated GPS or can I use my phone? A dedicated GPS has better battery life (16+ hours vs 4-6), works without cell service, is waterproof and rugged, and has purpose-built navigation features. Phones work as backup but are unreliable as primary navigation in the backcountry.
