Prepare your device
Charge your device, review location permissions, and test the field tools you plan to use. Bring suitable backup navigation and power.
Check the actual area
Download supported offline topo areas before departure and verify them with mobile data unavailable. An online map preview is not proof that the same area is stored offline.
Verify current access
Check current official closures, land access, route conditions, and activity rules. Mapped trails and historic reference boundaries do not establish current legal access.
Know the limits
GPS availability and accuracy vary. DeadZone does not guarantee a safe route or a return path. It is not an emergency communication service; local sound and light tools do not contact rescuers.
Check the current Google Play listing and your installed version for available features and coverage.
