7080 Type Approved Speed Log

Integrated Speed Log, Wind and Weather Data System

Walker 7080 is an integrated log, wind and weather system that includes a true wind option. Ship’s speed and distance travelled is derived from a Walker electromagnetic (EM) log transducer. Alternatively, log NMEA 0183 serial data may be used. Calibration of the EM log may be performed using ship’s GPS. Wind speed and direction is derived from input relative wind NMEA serial data. A comprehensive range of Walker wind sensors are available. True wind data can be calculated given suitable inputs
