SteadyCast Compass

Garmin's SteadyCast Compass (part number 010-11417-10) is a heading sensor designed to provide accurate directional data to chartplotters and marine radar systems. It ensures reliable alignment of the bow on the chartplotter screen with the boat's actual heading, which is critical for navigation and fishing operations.

This sensor integrates a 9-axis MEMS (Micro-Electro-Mechanical Systems) technology, enabling precise heading measurement.

No, the SteadyCast sensor is not a GPS device. It does not require an unobstructed view of the sky to function.

Its primary role is to provide precise heading data for chartplotters and marine radar systems, ensuring reliable bow orientation on the display and facilitating navigation and fishing.

For installation, you will need safety glasses, a drill, a 3.2 mm (1/8 in) drill bit, and possibly a 25 mm (1 in) drill bit for cable routing. A Phillips screwdriver, cable ties, and a handheld compass are also recommended. Additional stainless steel or brass screws of suitable quality may be required if the supplied ones are unsuitable for the mounting surface.

It is important not to install or store the sensor near strong magnets, including speakers, as a strong magnetic field can damage the sensor. The sensor must also not be mounted near known ferrous metal objects, such as a toolbox or a compass.

For optimal performance, choose a location away from ferrous metal objects and strong magnetic fields. Use a handheld compass to test for magnetic interference at the intended spot with the boat, engines, and other equipment powered on. If the compass needle moves, select a different location.

Yes, the sensor can be mounted in any orientation. It does not need to be installed in the same horizontal plane as the boat.

Yes, you will need to drill two pilot holes to secure the sensor. If you plan to run the cable through the mounting surface, a 25 mm (1 in) cable pass-through hole will also be required.

If you use mounting hardware other than the supplied screws, it must be made of stainless steel or brass to avoid magnetic interference with the sensor. It is recommended to test all mounting hardware with a handheld compass to ensure there are no magnetic fields.

Yes, this sensor is designed to connect to an existing NMEA 2000 network on your boat.

Yes, automatic heading alignment is only available if a GPS source is connected to the NMEA 2000 network. If no GPS source is connected, you must perform a fine heading alignment manually.

Yes, after installation it is essential to calibrate the heading sensor to obtain the best results. The calibration method will depend on the types of devices connected to your NMEA 2000 network.

If the sensor is connected to a compatible Garmin chartplotter, you will be prompted to start the calibration via the menu when the chartplotter detects the new sensor. Follow the on-screen instructions until calibration is complete, ensuring the boat remains as stable and level as possible. You can also open the calibration page at any time via Menu > Settings > Communications > NMEA 2000 Devices.

If you connect the sensor to an NMEA 2000 network without a compatible Garmin chartplotter, you will need to perform a basic calibration. Instructions for this method are available in the product documentation.

You must update the software on all your Garmin devices when installing this sensor. The update requires a Garmin NMEA 2000 Network Updater accessory or a Garmin chartplotter connected via the NMEA 2000 network. You will need to load the new software onto a memory card (up to 32 GB, formatted as FAT32) using a Windows computer, then insert the card into the chartplotter and follow the on-screen instructions.

If you do not have a computer with Windows software, you can contact Garmin customer support to order a preloaded memory card with the software update.

You can register your device online by visiting my.garmin.com. Registration allows Garmin to better assist you and provide enhanced support. It is also recommended to keep the original or a copy of your sales receipt in a safe place.

Yes, if automatic heading alignment is not available (for example, without a GPS source on the NMEA 2000 network), you will need to align the heading by manually adjusting the sensor installation so that the arrow points parallel to the bow of the boat.
