Product Overview

Supplies accurate heading and rate-of-turn information to compatible Simrad, Lowrance or B&G autopilot, radar and navigation systems over an NMEA 2000 connection.

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.

NMEA 2000 Heading and 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, multi-function 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.
