The Rino 110 is a GPS-enabled handheld that integrates radio functionality to provide two-way communications. It's waterproof, can send communications up to five miles (using GMRS channels), and can "beam" your exact location to another Rino user within a two-mile range (on the FRS spectrum) using "Position Reporting". And because the Rino 110 has standard FRS capabilities, you can talk to friends or family who own conventional FRS radios.
