An AIS transponder on your boat automatically receives information broadcast by other AIS-equipped vessel’s and base stations, all while your own vessel’s static and dynamic information is being transmitted. AIS signals may reach where radar cannot, showing AIS-equipped vessels that might otherwise be hidden, such as on the other side of an island or behind a larger vessel. SOLAS commercial vessels are already required to carry a Class A AIS transponder, so your position will be known by nearby large vessels. The MA-500TR increases your safety at sea.
