Imagine navigating choppy waters where traditional compasses falter due to magnetic interference or complex installations. The Precision-9 Compass changes that equation entirely. This compact powerhouse uses advanced nine-axis motion sensing to deliver pinpoint heading, rate of turn, pitch, and roll data straight to your NMEA 2000 network. Boat owners rave about its stability for autopilots that hold course like a pro, radar overlays that stay rock-solid, and displays that reflect true vessel attitude—no guesswork involved.
Unlike older fluxgate models prone to deviation errors from onboard electronics or metal hulls, the Precision-9's MEMS-based solid-state sensors ignore those headaches. Calibrate once, and enjoy ±2° heading accuracy that holds up under dynamic conditions, like quick turns or rolling seas. It's the go-to for weekend warriors and commercial operators alike who demand performance without the fuss.
Plug into the NMEA 2000 ecosystem, and watch your Simrad, B&G, or compatible setups come alive. Autopilots gain responsive control with 20 Hz heading and ROT updates, while radar systems benefit from stabilized MARPA tracking. Multifunction displays show real-time pitch and roll at 10 Hz, helping you read sea state like an open book. Heave data rounds it out for sonar precision in rough conditions.
Installation shouldn't be a battle against your boat's layout. The adjustable bracket lets you bulkhead-mount below deck or go external up-mast on steel hulls—IPX7 waterproofing handles spray and submersion like a champ. Keep it 0.5 meters from magnetic sources, and you're set. Single-cable NMEA 2000 connectivity means fewer wires, quicker setup, and less clutter in tight spaces.
Pro tip: Mount it high and forward to minimize roll interference, then run the user-prompted calibration routine on calm water. Rotate 360° as instructed, and lock in that accuracy for years of trouble-free service.

Fishermen love how it stabilizes sonar views during trolling. Cruisers appreciate autopilot confidence on long passages, reducing fatigue. Racers gain an edge with precise ROT for tactical maneuvers. Even on multihulls, where motion is amplified, it delivers stable data that legacy compasses can't match. Backed by robust construction, it thrives in salt air and extremes, making it a smart upgrade for any setup.
It uses solid-state nine-axis sensors for superior accuracy and resistance to interference, eliminating gimbals and fluids that plague older designs. Calibration is simpler, and it handles dynamic motion better.
Yes, its IPX7 rating supports external up-mast installs, ideal for steel vessels to dodge magnetic fields. Use the adjustable bracket for secure positioning.
Heading and rate of turn update at 20 Hz for responsive control, while pitch, roll, and heave refresh at 10 Hz—plenty for most marine applications.
Not at all—it's automatic and user-prompted. Just follow on-screen turns in calm conditions, and it self-adjusts for ±2° accuracy.
Perfect for NMEA 2000-compatible autopilots from Simrad, B&G, and others. It supplies all needed heading and motion data for seamless operation.
Maintain a 0.5-meter safe distance from magnetic sources like speakers, motors, or steel to ensure optimal performance.
This compact sensor package provides heading, rate of turn, pitch and roll data to equipment connected over an industry-standard NMEA 2000 ® network. More than just a compass, the Precision-9 is an ideal source of heading and motion data for Simrad autopilots, radar systems, multifunction displays, and other systems. The Precision-9 measures motion on nine separate axes in order to calculate the most accurate heading and rate-of-turn information possible. Its sophisticated solid-state design avoids many common limitations of conventional fluxgate electronic compasses, and delivers heading accuracy of ±2 degrees after calibration. An easily adjustable mounting bracket allows the Precision-9 to be installed on any vessel, in almost any location. The Precision-9 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.
