Parts Desk Insights
Best Use Case: An excellent choice as a primary VHF radio on kayaks, tenders, dinghies, and small powerboats where a fixed-mount radio is not practical. The floating, IPX8-submersible design and Class D DSC make it one of the more capable handheld options for offshore and coastal safety use. Also widely used as a backup or crew radio on larger vessels, and as a go-bag emergency radio for offshore passages. The included charging cradle and Li-Ion battery make it more convenient for regular onboard use than AA-powered alternatives.
Installation Notes: No installation required — fully portable handheld. Charges via included cradle with AC and DC cables. DSC distress calling with position data requires connection to an external GPS source via the radio’s NMEA 0183 input or manual position entry. Antenna is built-in; no external antenna required.
Compatibility: NMEA 0183 input for GPS position data (DSC). Not NMEA 2000 compatible. Compatible with optional Uniden speaker-microphone accessories. Operates on all international VHF marine channels including Channel 16 and Channel 22A.
