The Sigma Iota GPS NAV is a low cost handheld solution for global mapping, navigation and document storage. Designed for preppers the device does not require any subscription to cellular service or to access maps.
The GPS NAV is preloaded with global terrain maps for the entire world. No data connection required — all map data is stored directly on the device.
Built in waypoint management allows you to save locations and navigate to them. Mark a camp, a water source, or an extraction point and route back to it from anywhere.
The device can point you toward the nearest water source, wooded area, building, major city or hospital wherever you are in the world. No internet required.
When access to information is limited the GPS NAV can ensure that useful information is always at hand. Users can upload their own documents to the device from their mobile device just by connecting to the GPS NAV wifi — no need to download apps or register.
