Product Description

Satellite Compass performance is not affected by ship’s speed, latitude, geomagnetism, etc. This hybrid integration of GPS receiver technology and a 3-axis solid-state rate sensor provide accurate and steady heading information, even when bridges or tall buildings block satellite signals. Unlike conventional magnetic and gyro compasses, accuracy is not affected by G-force or velocity.

The SC50 offers highly accurate GPS WAAS Data for SOG, COG, ROT, and L/L. Multiple, programmable hi-speed heading data outputs allow you to send this information where you need it, and our unique Analog Pitch and Roll Output can be used to enhance your Furuno Sonar System.
