❓ 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.
❓ What maps do I need for hiking GPS?
Topographic maps with contour lines, trails, and water features. Most units accept downloadable maps. Free options include OpenStreetMap-based topo maps. Premium maps offer more trail detail.
