Know before you buy
No, the SSC300 comes factory calibrated for immediate use. It also features automatic deviation calibration, which continuously refines its accuracy while you are underway.
Yes, the device is designed to output data to both network standards at the same time, allowing for seamless integration with a wide variety of marine electronics.
By using a 3-axis rate gyro and advanced digital filtering, the SSC300 provides a stable, high-speed heading reference. This prevents the 'jitter' often seen in radar overlays and provides the precise data your autopilot needs to maintain a true course in rough seas.
Yes, the SSC300 is built with a robust IP67-rated waterproof enclosure, meaning it is fully protected against dust and can withstand immersion in water up to one meter deep.
The SSC300 updates your heading ten times per second. This high update rate ensures that your navigation data remains accurate and responsive, even during rapid or dynamic maneuvers.
