EM TRAK B350 Class B SOTDMA AIS Transponder

EM TRAK B350 Class B SOTDMA AIS Transponder

As a high powered AIS Class B the B350 transmits at over twice the power of standard AIS. This Threfore gives you increased range, as well as transmitting up to 5 times more frequently.  This is achieved by using the priority SOTDMA transmit method.  This is useful for mariners operating in busy areas or times of low visibility.  Moreover this capability is further enhanced by HF-AIS technology.  HF-AIS enables you to see more AIS targets. Finally the B350 is capable of this performance whilst maintaining ultra-low power consumption.

The B350 is small and entirely water and weather proof and comes with an integrated high-performance GPS antenna making an external antenna optional in most installations and providing complete installation flexibility and convenience.

The B350 is the perfect choice for the serious mariner looking for uncompromised quality and performance within a small package and competitive price.
