Precision-9 Compass

Part # 000-12607-001.

The Precision-9 Compass supplies accurate heading and rate-of-turn information to Simrad autopilot, radar and navigation systems over an NMEA 2000® connection. With an internal array of solid-state sensors constantly measuring motion and orientation on nine axes, the Precision-9 also provides pitch and roll data to compatible equipment. An easily adjustable mounting bracket and single-cable connection allow simple installation aboard any vessel, including up-mast mounting suitable for steel hulls.

Key Features

  • Heading, Rate Of Turn (ROT), pitch and roll output over NMEA 2000®
  • Accurate and reliable solid-state sensor technology
  • Heading accuracy of ±2° after calibration
  • Easily adjustable mounting bracket allows bulkhead or up-mast installation
  • IPX7 waterproof for external up-mast mounting on steel hulled vessels
  • Simple installation with a single NMEA 2000® connection
Where To Buy

    NMEA 2000® Heading & ROT Output

    With NMEA 2000® output, the Simrad Precision-9 Compass provides heading, Rate Of Turn (ROT), pitch and roll information to connected equipment including autopilots, radar, multifunction displays, and other navigational systems.

    Solid-State Sensor Technology

    The Precision-9 Compass incorporates a sophisticated solid-state sensor array based on MEMS technology. This high-precision array measures motion on nine separate axes in order to calculate the most accurate heading and rate-of-turn information possible, avoiding many common limitations of conventional fluxgate electronic compasses and delivering heading accuracy of ±2 degrees after calibration.

    Mount Almost Anywhere

    An easily adjustable mounting bracket allows the Precision-9 Compass to be installed on any vessel, in almost any location. The compass may also be mounted directly to any flat surface and, with an IPX7 waterproof rating, external up-mast installation is possible on steel hulled vessels to avoid magnetic interference. Installation is further simplified by NMEA 2000® connectivity, with a single cable carrying both power and data.
