Furuno SCX20 Satellite Compass - NMEA 2000 Product Description
Discover Unmatched Precision on the Water with Quad-Antenna Technology
Imagine navigating through choppy seas or tight marinas where traditional compasses falter due to magnetic interference or limited satellite views. The Furuno SCX20 changes that equation entirely. By harnessing four independent GNSS antennas, it delivers heading data that's not just reliable—it's transformative for your vessel's entire electronics suite. Whether you're running radar sweeps, tracking fish with sonar, or letting the autopilot handle long hauls, this compact dome unit ensures every reading is sharp and steady.
Boaters and anglers rave about how it stabilizes echo trails on radar displays, making target acquisition intuitive even in rough conditions. No more zigzagging trails or blurry sonar images—the SCX20's multi-baseline calculations (six possible from four antennas) lock in accuracy when others lose signal.
Key Advantages That Elevate Your Onboard Systems
- Superior Heading Stability: Achieves 1.0° accuracy, outperforming single or dual-antenna setups by using any of six baselines for computation. Ideal for stabilizing autopilots during fuel-saving straight-line courses.
- Full Attitude Data: Provides pitch, roll, and heave alongside 3-axis speed, helping sonars and fish finders maintain crystal-clear bottom contours in heavy swells.
- Environmental Insights: Outputs air temperature and barometric pressure, aiding weather-aware decisions without extra sensors.
- Compact and Versatile: Its low-profile dome minimizes wind resistance and multi-path errors, fitting seamlessly on t-tops, hardtops, or cabin roofs.
- Rate of Turn Precision: Tracks ROT up to 10°/second, enhancing collision avoidance and maneuverability displays.
How the SCX20 Transforms Radar, Sonar, and Autopilot Performance
In real-world scenarios, heading fluctuations plague lesser compasses, turning radar echo trails into confusing scribbles. The SCX20's quad design keeps trails straight and true, revealing vessel paths with pinpoint clarity. Pair it with modern multifunction displays, and watch sonar images stay rock-steady—crucial for spotting structure in 10-foot seas.
For autopilots, precise COG/SOG and attitude data mean tighter tracking, reduced rudder wear, and optimized fuel burn on offshore runs. Fishermen benefit from stabilized vertical readings, ensuring no fish slips by due to boat motion. It's not just data; it's confidence in every decision.
Seamless NMEA2000 Integration for Plug-and-Play Reliability
Fully certified for NMEA2000 networks, the SCX20 drops into existing setups with minimal wiring. Share its high-fidelity data across chartplotters, instruments, and engines effortlessly. Configuration is straightforward via compatible multifunction displays or dedicated software, getting you up and running fast.
Its GNSS receiver supports GPS, GLONASS, Galileo, QZSS, and SBAS for global coverage, locking onto satellites even in obstructed environments like canyons of condos or under arches.

Frequently Asked Questions
What makes the Furuno SCX20 different from traditional satellite compasses?
Unlike dual-antenna models that rely on a single baseline, the SCX20 uses four antennas for six possible baselines, delivering superior accuracy in obstructed views and dynamic conditions.
How does the SCX20 improve radar performance?
It provides rock-steady heading data, resulting in clear, straight echo trails that make target tracking reliable, even when competitors show zigzags or blurs.
Is the SCX20 suitable for all boat sizes?
Yes, its compact design and flexible mounting suit everything from center consoles to larger yachts, with NMEA2000 plug-and-play for easy integration.
What data outputs does the SCX20 provide?
Heading, position, COG/SOG, ROT, roll/pitch/heave, 3-axis speed, plus air temperature and pressure—perfect for comprehensive marine networks.
Can the SCX20 work in areas with poor satellite visibility?
Absolutely; the quad-antenna array excels here, computing data from limited satellites where others fail.
Does it require calibration after installation?
Initial setup is simple via NMEA2000 interfaces or software, with no complex magnetic calibration needed like fluxgate compasses.
How accurate is the speed data from the SCX20?
It offers 0.02-knot precision through dual-axis speed logs, far surpassing basic GPS-derived speeds.
SCX20 Satellite Compass
Utilizing four separate GNSS Antennas for the ultimate in responsiveness, the SCX20 sets a new standard for reliable and accurate heading for all of your marine electronics. The four antennas ensure reliable heading performance, even under the most challenging of conditions. The unprecedented quad antenna design of the SCX20 makes it capable of calculating extremely accurate heading, pitch, roll, and heave information, even when line of sight is limited to only a single satellite. They greatly enhance the performance of onboard equipment such as Radar, Fish Finders, Sonar, and Autopilots.
Features:
- Outputs accurate Time, Position, Heading, COG/SOG, ROT (10 degrees/second), Roll/Pitch/Heave 3-Axis Speed, Air Temperature and Air Pressure data
- Unprecedented heading accuracy for Radars, Sonars, and Navigation
- 1.0 degree heading accuracy, 0.02 knot speed accuracy
- Extremely compact with easy and flexible installation for reduced susceptibility to multi-path interference
Furuno SCX20 Compact Dome Satellite Compass, NMEA2000® Certified
Model: SCX20Utilizing four separate GNSS Antennas for the ultimate in responsiveness, the SCX20 and SCX21 set a new 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 SCX20 and 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.
The SCX20 and SCX21 enhance the performance of on-board equipment such as Radar, Fish Finders, Sonar, and Autopilots. Accurate heading information empowers your NAVpilot to keep a better course, saving time, fuel, and money on every voyage; meanwhile, precise pitch, roll, and heave information stabilizes the display for many Furuno Fish Finders and Sonars, allowing for an accurate presentation even in the roughest of seas.
Full NMEA2000 Certification provides plug and play connectivity to any NMEA2000 network. Distribute high-accuracy navigation data as well as air temperature and barometric pressure. Initial Setup and configuration can be done from any Navnet TZT2/TZT3 MFD, Navpilot 300, or use the free Furuno SC Setting Tool PC Software when properly interfaced.
When connected to Furuno SCX20/21, the Radar’s echo trails hold steady and clearly depict an accurate echo trail thanks to the SCX20/21’s amazing accuracy. Company A’s satellite compass fails to uphold a steady heading, making echo trails virtually unintelligible. Company B’s heading accuracy fluctuates by +/- 3? with a slower update, causing an echo trail that has a wide zig-zag pattern. Company C’s heading accuracy fluctuates by +/- 5? with a faster update, causing an echo trail that is indistinguishable and confusing.
