A large format, multi-mode wind display for the professional user that provides real time information on wind speed and direction via both analogue and digital displays for maximum clarity. The WI80 ensures that critical wind data can be monitored in the most intuitive fashion via simultaneous display in two complementary formats. As part of the IS80 instrument range from Simrad it sets the very highest standards in reliability and accuracy and is ideal for long periods of continuous use in all conditions. Interfacing the WI80 with other systems is straight forward with a high level of compatibility. Wind data is accepted via NMEA0183 or SimNet, valid data received via NMEA0183 is then re-transmitted onto SimNet for use by additional system displays. The SimNet network also allows the lighting of the whole system to be controlled centrally.
