Garmin Rino 120 GPS Navigator with 2 Way Radio
The Rino 120 is state-of-the-art GPS navigation and two-way communications combined, with enough memory to download detailed mapping for driving, hiking, hunting, fishing - or just about anything else you can dream up. It's waterproof and can ""beam"" your exact location to another Rino user within a two-mile range (on the FRS spectrum) using ""Position Reporting"". The radio functionality of the Rino 120 provides two-way communications for up to two miles (using FRS channels), and you can talk to friends or family who own conventional FRS radios. There's also a voice scrambler and a vibration mode for silent calls.
