Simrad HS65 GNSS Compass

SKU: 000-16235-001

The HS65™ delivers high-precision GNSS heading with <2° RMS accuracy, providing stable navigation data immune to the magnetic interference* that affects traditional compasses. Its dual-layer backup system uses integrated Dead Reckoning to maintain reliable heading for up to three minutes during temporary GNSS signal loss before automatically switching to magnetic backup. With seamless NMEA 2000® integration and a sleek low-profile design, the HS65 delivers dependable performance for autopilot, radar overlay, and modern navigation systems.

Product details

Precision on the water starts with reliable heading data. The HS65 GNSS Compass uses advanced GNSS technology to deliver <2° RMS accurate heading and positioning information that enhances navigation, radar overlay, and autopilot performance.

Unlike traditional magnetic compasses, GNSS-based heading is immune to magnetic interference* from onboard electronics or metal structures. The result is stable, dependable heading data that keeps charts aligned, radar overlays accurate, and your vessel confidently on course.

The HS65™ features a dual-layer backup system designed to maintain reliable heading data. If GNSS signal is temporarily lost, built-in Dead Reckoning seamlessly maintains reliable heading for up to three minutes before automatically switching to magnetic backup for continued heading data and added confidence when conditions change.

Combining a compass and GNSS receiver in one streamlined sensor, the HS65 simplifies installation while reducing system complexity. A sleek, low-profile design, flexible mounting options, and improved cable routing make it easier than ever to install cleanly on modern boats.

Compatible with Simrad systems via NMEA 2000®, the HS65 integrates seamlessly with chartplotters, autopilots, radar, and AIS—delivering precise heading data your entire navigation system can depend on.
