About the Garmin SteadyCast™

Get oriented

The chartplotter says the boat's here and the fish are over there. Simple, right? Well, usually, but not always. Garmin's SteadyCast™ heading sensor will align the bow to its actual orientation so you'll know exactly where you're casting.

Accurate headings at any speed

Whether you're trolling or just floating, the SteadyCast will make sure your chart orientation and boat heading align with actual reality. With a heading output rate of 10 Hz and a heading accuracy of plus or minus 3 degrees, you'll always know exactly where you are, even in rough waters.

Easy to install

The SteadyCast is easy to install on your boat, thanks to a NMEA 2000® plug-and-play interface. A 2-step calibration process connects it to your compatible Garmin chartplotter, and it also works with echoMAP™ models and other NMEA 2000 displays. You can install it in pretty much any orientation away from magnetic interference and it's even tough enough to survive installation in a bilge.

More details on the Garmin SteadyCast™

Product Research


Overview: The Garmin SteadyCast is a nautical heading sensor that helps to ensure your vessel's orientation matches the heading on your chartplotter. SteadyCast can interface with your chartplotter via the existing NMEA 2000 network on your boat. An NMEA 2000 T-connector is included.

Accuracy: SteadyCast uses the earth's magnetic field to precisely determine your heading. It outputs its heading reading 10 times per second (10 Hz), and is accurate within +/- 3 degrees. The heading accuracy is the same whether your boat is sitting still or at full speed ahead, or in calm or rough waters.

Calibration: After the sensor is installed, it must be calibrated for best results. When connected to an NMEA 2000-compatible Garmin chartplotter, calibration is a menu-based function. Without a compatible Garmin chartplotter, the basic calibration procedure involves completing two full, slow, tight circles with your vessel to calibrate the compass and align the heading.

Installation: The SteadyCast module mounts with the supplied screws, and can be installed with the cable routed through the side of the sensor, or routed through the mounting surface under the sensor. It should not be mounted near a strong magnetic field (such as a speaker), or near ferrous metal objects, such as a toolbox or compass. As it is not a GPS device, it does not require a clear view of the sky.
