Garmin Heading Sensor, NMEA 2000/NMEA 0183, 3-Axis Compass, IPX6

Overview

The Garmin 010-11417-00 is a 3-axis heading sensor that outputs heading data over NMEA 0183 or NMEA 2000 for accurate radar overlay and MARPA functions on compatible systems. It uses a solid-state compass with an integrated accelerometer and rate gyro, delivering better than 1 degree static heading accuracy and 2 degrees dynamic accuracy with up to 30 degrees of pitch and roll.

It runs on 9 to 16 VDC and comes in an IPX6-rated housing for wet helm areas and washdowns. Physical size is about 2 in high by 4.4 in long by 4.5 in deep, which helps when space is tight inside a console or under a dash.

Key features

• Better than 1 degree static heading accuracy; 2 degrees dynamic accuracy with up to 30 degrees of pitch and roll
• Heading output is 10 Hz by default on both NMEA 0183 and NMEA 2000; NMEA 2000 output can be up to 20 Hz
• NMEA 0183 and NMEA 2000 data output support to fit different network and wiring setups
• Three-axis solid-state compass plus accelerometer and rate gyro for stable heading data when the boat is moving
• IPX6-rated waterproof housing for spray and deck wash conditions
• Mounts on an angled bulkhead and supports auto-calibration for a shorter setup process

Installation and setup

Mount the sensor on a solid surface where it will not be kicked or used as a handhold. Like any compass-based sensor, it needs some distance from magnetic sources such as speakers, large DC motors, or high-current wiring runs.

The enclosure can be mounted on an angled bulkhead, which helps when the best location is under a console or inside a helm station. After mounting and wiring, complete the calibration steps on the connected display so the heading aligns correctly with the boat.

Electrical and data output

Power range is 9 to 16 VDC. Data output can be set up on either NMEA 0183 wiring or a NMEA 2000 backbone, depending on how the rest of the electronics are networked.

NMEA 0183 and NMEA 2000 cables are sold separately, so plan the correct cable type for your existing system before installation.

Compatibility and fit

This sensor is used when a vessel needs consistent heading input for features like radar overlay and MARPA tracking. Confirm that your display, radar, or other onboard electronics accept heading input via NMEA 0183 or NMEA 2000 and that the installation location can stay clear of magnetic interference.

Use cases on board

A good match for helms that rely on radar overlay, MARPA target tracking, or any setup where heading needs to stay steady during turns, chop, and acceleration. It also fits well on boats that see frequent pitch and roll, since the rate gyro helps maintain heading accuracy under dynamic motion.

Maintenance and care

Periodically check that the mounting hardware stays tight and that the cable routing is supported so vibration does not work the connections loose over time. If electronics are moved near the sensor later, re-check heading alignment since magnetic changes onboard can affect compass-based devices.

Shipping
We ship worldwide from the United States. Rates are calculated at checkout based on destination and package weight. Some items include free shipping, which will show automatically. Not every product is eligible for international shipping; checkout will confirm eligibility. We do not ship to PO Boxes except through USPS, and not all packages qualify.

Delivery and tracking
Deliveries are handled by trusted carriers such as USPS, UPS, FedEx, and DHL. Estimated arrival times appear at checkout and depend on your location and the service you choose. These are estimates and can be affected by customs or carrier disruptions. A shipping confirmation with a tracking link is emailed when your order ships, and tracking may take up to 24 hours to update. You can also view tracking in your account.

Duties, taxes, and support
International customers are responsible for any customs duties, taxes, and fees charged by the destination country. If these charges are refused and a shipment returns to us, the carrier’s return cost and any re-entry customs fees will be deducted from the refund. If your order is late or you need help, contact cs@qualityboatparts.com and we will assist you.

Quality Boat Parts is a reseller. Many items include a manufacturer’s warranty, and all warranty service is handled directly by the manufacturer. We do not manage or administer warranty claims on behalf of customers.

Warranty terms, coverage, and duration are set by each manufacturer. Issues involving defects, repairs, or replacements must be addressed with the manufacturer’s support team. When available, the warranty period is listed on the product page. If it is not shown, contact us or the manufacturer for details before purchasing.

To start a claim, the customer must contact the manufacturer and follow their process. Keep your proof of purchase and original packaging, and register the product if the manufacturer requires it, as these are often needed for warranty service.
