AMEC B650

Supplied with GA-22 GPS Antenna

Take your vessel's AIS performance to the next level with the AMEC B650 AIS Class B SOTDMA Transponder. Designed for commercial operators, fishing vessels and serious leisure boaters, the B650 delivers greater transmission range, faster position reporting and improved communication reliability compared to conventional 2W Class B AIS transponders. Built on AMEC's latest third-generation AIS platform, it provides outstanding situational awareness in busy waterways and offshore environments.

Utilising 5 Watt SOTDMA (Self-Organised Time Division Multiple Access) technology, the B650 secures transmission slots in advance, allowing your vessel's position to be updated more frequently and received more reliably by nearby vessels and shore stations. This makes it an excellent choice for vessels operating in congested traffic areas or where enhanced visibility is essential.

The B650 features an integrated 72-channel multi-constellation GNSS receiver, supporting GPS, Galileo, GLONASS and BeiDou for accurate positioning. Installation is straightforward thanks to support for NMEA 2000®, dual bi-directional NMEA 0183 ports and USB-C connectivity for configuration and software updates. Its rugged IP68 waterproof enclosure is designed to withstand demanding marine conditions.
