Simrad HS75 Compass GNSS
Best precision navigation tool for serious boaters and commercial captains.
The Simrad HS75 Compass GNSS is a vital navigation tool for marine vessels, ensuring precise heading for autopilots, radar, and other electronics. It utilizes multi-GNSS (GPS, GLONASS, BeiDou, Galileo, QZSS) for accurate global positioning and heading, even when stationary. Integrated gyro and tilt sensors provide enhanced performance and temporary heading data during GPS signal loss. With a high-speed receiver updating position up to 20 times per second, it's ideal for fast boats. The HS75 also calculates rate of turn, heave, pitch, and roll, outputting data via NMEA 2000® for optimal system performance. Its compact design allows for simple installation.
