The Windvane transducer is compatible with the i60, i70, ST60+, ST70 and ST70+ instruments on the SeaTalkng network via an iTC-5 transducer converter (sold separately). The transducer is connected to the iTC-5, which converts the transducer signals to SeaTalkng. The iTC-5 is then connected to your SeaTalkng backbone. The Windvane transducer can also use a ST70 wind pod to connect to the SeaTalkng network. Short arm vane is supplied with 30m (97.5') cable.
