super AIS-Empfänger
best upgrade on board my sailing boat, the AIS view is the default view for me, range and proximity alarm can be adjusted quickly and without instructions, so in the busy traffic is not always the alarm and you do not lose track on the display, street of Messina was no problem at night, although the position lights of the ships are not recognizable because of the background lights. It was no problem with the radio to see the shadows of the ships, because you knew where to look. In addition the AIS information over the ships like speed, distance, course. The alarm is so loud that you wake up from a sleep exhaustion at the night watch and with the engine running. On the Adriatic, all boats had AIS stations at night. Some of the fishermen left the AIS near the coast of the Tyrrhenian Sea, which they suddenly did. Connection and operation possible without manual. Just do not come in the DSC menu and have not found anything in the manual. MMSI input is very simple. VHF reception seems to me really good.
