Lowrance Precision-9 Compass — NMEA 2000 Heading Sensor for Marine Autopilot

The Precision-9 Compass from Lowrance delivers precise, reliable heading and motion data to your marine autopilot, radar, and navigation systems over a single NMEA 2000 connection. Built around a solid-state, nine-axis sensor array, it continuously measures heading, rate of turn, and vessel attitude (pitch, roll, and heave) to keep your course steady and your electronics aligned with real-time motion.

Designed for demanding marine environments, this compact sensor provides:

• Accurate heading data with ±2° heading accuracy after calibration for confident course-keeping.
• Rate of Turn (ROT) and full attitude information (pitch and roll) broadcast to compatible equipment, helping autopilots respond quickly and smoothly to changing conditions.
• Single-cable NMEA 2000 connection and 12V DC supply via the bus, simplifying installation and reducing wiring clutter on deck or in the cabin.
• Solid-state reliability with continuous 9-axis measurements, delivering consistent data even in rough seas or with vessel movement.
• IPX7 waterproof protection suitable for external up-mast mounting on steel-hulled vessels, expanding installation options without compromising durability.
• Flexible mounting with an easily adjustable bracket for bulkhead or up-mast configuration, so you can place the sensor where it performs best on your boat.
• Compact, purpose-built design (36 x 119 x 119 mm) and lightweight construction for easy integration into existing layouts on larger or smaller craft.
• Key identifiers including part number LOW-000-12607-001 and a 2-year warranty for peace of mind.

In practice, the Precision-9 enhances navigation confidence by feeding your autopilot with trustworthy heading and motion data, improving course stabilization when crossing currents, waves, or busy radar returns. Its attitude information also benefits radar alignment and route planning, ensuring your displays and guidance systems stay in sync with the vessel’s real-world orientation.

What makes this Lowrance sensor stand out

• Nine-axis solid-state sensing yields robust heading and motion data under dynamic conditions, reducing autopilot drift.
• Dedicated output for magnetic heading, rate of turn, pitch, roll, and heave—the data your marine electronics rely on to react quickly and accurately.
• Designed for practical marine installation, with an adjustable mount and a straightforward NMEA 2000 connection that minimizes setup time and wiring complexity.
• Up-mast mounting capability on steel hulls expands installation flexibility where visibility and protection from vibration are critical.
• Low power draw on the NMEA 2000 network and compatibility with widely used Lowrance autopilots, radar, and navigation systems.
