Garmin SteadyCast™ Heading Sensor

Why Boaters and Anglers Trust the Garmin SteadyCast Heading Sensor

Imagine gliding across the water, your chartplotter displaying a precise bow orientation that matches exactly where your boat is pointing—no guesswork, no frustration. The Garmin SteadyCast heading sensor delivers this reliability using advanced 9-axis MEMS technology, combining gyroscope, accelerometer, and magnetometer data for rock-solid heading accuracy of ±3 degrees at a smooth 10 Hz update rate. Whether you're trolling for bass, navigating tight channels, or overlaying radar returns, this sensor ensures your display stays true to reality, even at dead-slow speeds or in choppy conditions.

Superior Performance in Real-World Boating Scenarios

Traditional fluxgate compasses often falter near metal or electronics, leading to erratic readings that throw off your charts, radar overlays, or MARPA target tracking. SteadyCast sidesteps these issues entirely. Mount it virtually anywhere—bulkhead, console, or bilge—as long as it's clear of magnetic interference. Its IPX7 waterproof rating shrugs off splashes, spray, and submersion, thriving in harsh marine environments from -15°C to 70°C.

• Pinpoint Casting Accuracy: Know precisely where your lure will land relative to your chartplotter's orientation.
• Reliable Low-Speed Stability: Maintains heading integrity while idling or drifting, perfect for finesse fishing techniques.
• Rough Water Resilience: Advanced stabilization keeps readings steady when waves pitch and roll your vessel.
• Enhanced Radar and Autopilot Integration: Unlocks superior overlay performance and target acquisition on compatible Garmin multifunction displays (MFDs).

Effortless Setup for Quick On-Water Results

Getting up and running is straightforward with the NMEA 2000 plug-and-play backbone. Simply connect the integrated 6-foot drop cable via the included T-connector to your existing backbone—no complex wiring required. For Garmin chartplotters like GPSMAP or echoMAP series, a quick 2-step precision calibration aligns everything perfectly. Other NMEA 2000 displays get basic calibration support too. Power it from 9-32 VDC sources, and you're ready to fish or cruise with confidence.

Pro tip: Position the sensor high and away from speakers, motors, or steel objects for optimal performance. Many users tuck it under the helm or in a dry locker, where its compact 3.4" x 2.1" x 1.3" size fits unnoticed.
