EM-TRAK Class B AIS Transceiver 5W – B951
The EM-TRAK B951 is a high-performance 5W Class B AIS transceiver designed to improve situational awareness by broadcasting your vessel’s position and allowing you to see other AIS-equipped vessels nearby. It provides a dependable, no-frills AIS solution using a wired connection to your chartplotter or navigation system.
- Class B AIS transceiver for transmitting and receiving vessel position data
- 5W transmit power for increased AIS range and visibility
- Built-in GPS receiver for accurate position reporting
- Wired AIS data output for reliable integration with onboard electronics
- Compact, marine-grade design for recreational and light commercial vessels
The B951 continuously transmits your vessel’s identity, position, course, and speed while receiving AIS targets from surrounding vessels. These targets are displayed on a compatible chartplotter or navigation system, helping skippers assess traffic, manage collision risk, and navigate confidently in busy waterways or reduced visibility.
This model is ideal for operators who want the increased range of a 5W AIS transceiver and a simple, hard-wired installation without the need for wireless connectivity or antenna sharing.
