The SeaTraceR AIS B Transponder from SevenStar was one of the first to be designed following the release of the IEC- 62287-1 specification. It utilises the most sophisticated digital signal processing and software algorithms to implement the required CS-TDMA transmitter and receiver functions. Robust and resilient to the stresses of life at sea, the SeaTraceR is housed in an IP-65 rated aluminium enclosure with matching and versatile mounting hardware, all of which is protected with a sea-water resistant coating under a heavy-duty powder-coat external finish.

Combined with a chart plotter or AIS-enabled radar set, it takes their performance into the next generation - once you've seen it in action, you won't believe you could have sailed without it!

These units are ideal for use on bouys, marine farms and other marine us for details.

Another feature of this units is "silent mode", you can continue to receive without transmitting; so you don't have to tell the world your favourate fishing spots!
