ComNav Mariner X2 AIS Class B Transceiver w/External GPS - Must Be Programmed

The ComNav Mariner X2 AIS Class B Transceiver with External GPS is purpose-built for recreational boaters, fishing captains, and cruising enthusiasts who demand real-time vessel traffic awareness without the complexity of commercial-grade systems. Whether you're navigating busy shipping lanes, coordinating with other boats, or enhancing your emergency communication capability, this Class B AIS unit delivers professional-grade situational awareness at a mid-range price point. The integrated external GPS antenna ensures reliable position fixing in coastal and offshore waters where satellite signal integrity is critical.

AIS (Automatic Identification System) Class B transceivers transmit your vessel's position, course, and speed to nearby traffic while simultaneously receiving broadcasts from other equipped vessels and coastal base stations, creating a dynamic picture of marine activity around you. The ComNav Mariner X2 operates on international VHF maritime frequencies and integrates seamlessly with chartplotters and multifunction displays via standard NMEA 0183 data protocols. The external GPS module provides standalone positioning accuracy and can be mounted away from potential RF interference, critical for reliable navigation data in areas with heavy electronic equipment. Weighing just 3.2 pounds and measuring 10 x 7 x 12 inches, the compact form factor fits standard cabin mounting locations without consuming valuable galley or electronics box space.

Anglers fishing organized tournaments will appreciate the traffic avoidance benefits when crossing shipping channels or operating in congested anchorages, while offshore cruisers gain confidence during extended passages through commercial zones. Installation requires professional programming to register your vessel's MMSI (Maritime Mobile Service Identity) number and assign your call sign—this step is non-negotiable for legal operation and proper AIS identification on the network. The unit pairs with existing VHF antennas and integrates with Garmin, Raymarine, Navico, and compatible multifunction displays, making it an ideal upgrade for boaters transitioning from basic radio to integrated vessel systems.
