Furuno SCX20 Satellite Compass – NMEA 2000

For the ultimate in heading and stabilization data, the Furuno SCX20 satellite compass sets the standard. This is not just a heading sensor; it is a quad-antenna, multi-GNSS powerhouse that provides an unprecedented level of accuracy and stability for your NMEA 2000 network. Its unique four-antenna design allows it to calculate heading using any of the six baselines between the antennas, providing a failsafe system that is incredibly resilient. It is completely immune to magnetic interference, making it the ultimate solution for any vessel.

The SCX20’s advanced quad-antenna array and inertial sensors provide a constant, ultra-smooth stream of heading, pitch, roll, and heave data. This makes it a cornerstone for high-end navigation suites, especially those with sophisticated sonar and autopilot systems. The IP56-rated housing is designed to be pole-mounted or surface-mounted, providing long-term reliability in the marine environment. It represents the pinnacle of heading sensor technology available for recreational and light commercial vessels.

Helm Use and Readability

The SCX20 transforms your helm without you ever looking at it. Its primary role is to feed your other systems the purest possible data. Autopilots hold courses with laser precision. Radar targets are locked and stable. Most impressively, the heave compensation data cleans up the image on compatible fishfinders, allowing you to see bottom structure and targets clearly even when the boat is bouncing in rough seas. It unlocks the full potential of your other electronics.

Why Choose the Furuno SCX20 High-Precision Quad-Antenna Multi-GNSS Satellite Compass

You choose the SCX20 satellite compass when you absolutely cannot compromise on data quality. Its quad-antenna design is its key differentiator, offering a level of redundancy and accuracy that other sensors cannot match. It is the essential backbone for advanced systems like Furuno’s DFF3D sonar or for any captain who demands the most from their autopilot. For serious offshore fishing or long-distance cruising, the SCX20 is the ultimate investment in safety and performance.
