Real-World Testing: Putting Furuno Elec. Compass, PG500R Rate Fluxgate to the Test

First Use Experience

My testing of this heading sensor was conducted primarily aboard my 38-foot sloop, both at anchor in a moderately exposed bay and during coastal cruising. These conditions provided opportunities to observe its performance through gentle swells, minor boat wakes, and steady wind. I was particularly keen to see how the rate compensated feature would handle the natural roll and pitch of a vessel underway.

The setup was straightforward, integrating with my existing Furuno NavPilot system. Power and data connections were secure, and the included 2-meter combo cable was sufficient for my installation. The automatic compensation (w/ GPS input) feature was a standout from the moment I powered it up; the heading data immediately locked onto GPS and provided a stable readout.

During extended use, I noticed how effectively this unit dampened the usual bouncing of a magnetic heading. Even when tacking or during minor course corrections, the data stream remained remarkably smooth. This level of stability was a significant upgrade from my previous setup, where minor boat movements could cause noticeable jitters in the displayed heading.

Extended Use & Reliability

Over several months of regular use, covering hundreds of nautical miles, the Furuno Elec. Compass, PG500R Rate Fluxgate has proven itself to be a steadfast performer. It has remained consistently accurate, even through varying sea states and occasional spray. I’ve intentionally kept it in place during cleaning cycles and have not performed any specialized maintenance beyond ensuring connections remain clean and tight.

The build quality is evident; despite exposure to salt air and humidity, there are no signs of corrosion or material degradation. It holds its position reliably, without any shifting or degradation in its output signal. Compared to less sophisticated magnetic compasses I’ve used in the past, this rate-compensated fluxgate is in a different league. Those older units often required recalibration after significant weather events or hull work, something this Furuno unit has seemingly rendered unnecessary.

Breaking Down the Features of Furuno Elec. Compass, PG500R Rate Fluxgate

Specifications

The core of the Furuno Elec. Compass, PG500R Rate Fluxgate is its identity as a Rate Compensated Fluxgate Heading Sensor. This means it doesn’t just measure the Earth’s magnetic field; it also incorporates data from an internal rate sensor to compensate for the vessel’s motion, such as pitch and roll. This automatic compensation (w/ GPS input) is critical for providing accurate headings, especially on a moving platform like a boat.

It comes with a 2M combo cable and data cable, which simplifies installation by providing both necessary connections in one flexible assembly. The primary intended use is for use w/ ARP10 or 11 radar plotters and NavPilot system, highlighting its role as a foundational component in a larger navigation suite. The unit itself is finished in a standard Black color, common for marine electronics, designed to blend in and withstand UV exposure.

These specifications matter because they translate directly into a more stable and trustworthy heading display for critical navigation functions.
