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.
Watcheye offers a special GPS antenna, whenever the internal antenna is insufficient. In our opinion the mini GPS is the best solution, as it is very small yet strong and it can be mounted on deck.
