You want better performance from your radar, fish finder and autopilot? A better satellite compass will do the trick, and the SCX20/21 is a great choice. With four internal GNSS antennas, the accuracy of heading, pitch, roll and heave data is significantly enhanced—even when only a single satellite is within view. In fact, this satellite compass is so advanced that heading accuracy is down to a single degree, and speed accuracy to an amazing 0.02 knots.
