Uniden GMR3689-2CK GMRS/FRS Two-Way Radio
The GMR3689-2CK is a pair of rugged, waterproof GMRS/FRS two-way radios with an advertised range of up to 36 miles in open conditions. Designed for outdoor and on-water use, they offer NOAA weather alerts, multiple channels, and a durable build — making them a practical communication solution for boating, camping, hiking, and worksite use where cellular coverage is unreliable.
Key Features

- Waterproof Construction — Built to handle rain, splash, and outdoor conditions

Parts Desk Insights
Best Use Case: Best suited for short-range crew communication on recreational boats, between vessels in a flotilla, or between boat and shore — particularly in areas where VHF marine radio is not required or as a supplemental communication tool. Also well-suited for camping, hiking, and outdoor recreation where a simple, licence-free (FRS channels) or low-cost GMRS option is needed. Not a replacement for a VHF marine radio for offshore or coastal safety use — these radios do not access Coast Guard monitoring channels (Channel 16) and are not recognized as marine distress communication devices.
Installation Notes: No installation required — fully portable, battery-powered handheld units. Charges via included dual charging cradle. Requires FCC GMRS licence for GMRS channel use in the United States; FRS channels are licence-free.
Compatibility: Standard GMRS/FRS frequencies — compatible with other GMRS/FRS radios on shared channels. Not compatible with VHF marine, CB, or MURS frequencies.
