The Watcheye B AIS transponder is a valuable piece of on board equipment, especially vital in open waters and during regattas. There is a clear view of what is happening which in turn leads to more safety. AIS offers information about other vessels within a certain range and transmits your information as well. So AIS is basically all you need.
The Watcheye B AIS transponder has to be connected to a VHF antenna. It is also possible to connect it to the Watcheye S AIS splitter, which divides the VHF signal between AIS and VHF. To display the AIS data it must be connected to a chart system; such as a plotter, PC or tablet.
