SCX21 Includes Only:
Utilizing four separate GNSS Antennas for the ultimate in responsiveness, the SCX21 set a standard for reliable and accurate heading for all of your marine electronics. Traditionally, a Satellite Compass calculates heading using one baseline between two antennas; the SCX20/21's four antennas can calculate heading information using any one of the six baselines drawn between the four antennas.
The unprecedented quad-antenna design of the SCX21 makes them capable of calculating extremely accurate heading, pitch, roll, and heave information. They are the perfect heading solution for complex vessel installations where the view of satellites may sometimes be obstructed.
