Overview

The Garmin 010-11417-10 is a NMEA 2000 heading sensor that keeps your chartplotter’s heading line and bow orientation in sync with the boat, even at low speed or when you are stopped. It outputs heading at 10 Hz with ±3° accuracy, so the on-screen view stays steady while you troll, drift, or set up a cast.

Power comes from the NMEA 2000 network (9 to 32 V DC), and the sensor can be mounted in any orientation as long as it is located away from magnetic interference. The housing carries an IPX7 water rating and measures 3.4 in x 2.1 in x 1.3 in, which helps when you are fitting it under a console or in other protected mounting spots.

Key features

• NMEA 2000 plug-and-play connection with an integrated 6 ft drop cable
• Heading output at 10 Hz with ±3° accuracy for a stable heading line on compatible displays
• 9-axis MEMS sensor package supports installation in any orientation when placed away from magnetic interference
• Calibration support through compatible Garmin chartplotters, with a basic calibration method for other NMEA 2000 displays
• IPX7 water rating for wet marine environments
• Compact sensor body (3.4 in x 2.1 in x 1.3 in) for easy placement in tight spaces

What’s included

• Heading sensor with integrated NMEA 2000 drop cable (6 ft)
• NMEA 2000 T-connector
• Documentation

Installation and setup

Mount the sensor where it will stay level with the boat and where it will not be affected by magnets or large ferrous objects. Common troublemakers include speakers, tool storage, and heavy-gauge power runs. The unit does not need to be mounted “upright,” but it does need a clean magnetic environment to hold its heading accuracy.

Connect the drop cable to a T-connector on your NMEA 2000 backbone. If the integrated drop cable does not reach your backbone, a drop cable extension up to 4 m (13 ft) can be used within NMEA 2000 guidelines.

Compatibility and network integration

This sensor is built for NMEA 2000 networks and is meant to supply heading data to chartplotters and marine displays that can read it. During calibration, avoid having multiple compass-based heading sources active on the network at the same time, since competing heading data can make setup and troubleshooting harder.

Use cases on board

This is a good match for fishing boats where you want the bow direction on the chart to match what the boat is actually doing while you work structure at slow speed. It also suits boats that spend time maneuvering in tight areas, where a steady heading line makes it easier to interpret what the plotter is showing in real time.

Maintenance and care

After the first few trips, recheck the mounting and cable routing and make sure nothing magnetic has been stored near the sensor. If the sensor is moved to a new location or the surrounding hardware changes, plan on recalibrating so the heading stays consistent.
