Ritchie FN-203 Navigator | 4.5-Inch Flush Mount Black Compass
Engineered to overcome dashboard glare, the Ritchie FN-203 Navigator features a classic black housing and a high-visibility 4.5-inch flat dial.

Tailored for permanent helm installation, the FN-203 includes internal gimbals and high-contrast markings.

Ritchie FN-203 Navigator Compass Technical Guide
The FN-203 is a commercial-grade flush mount compass with a 4.5-inch flat card dial. Its black housing and high-contrast markings are designed for maximum legibility on professional workboats and serious offshore fishing consoles.
Yes, the PowerDamp baffle system is standard in the FN-203. This technology is specifically designed to eliminate dial "jitters" caused by high-RPM engines or rough water, providing a smooth and readable heading at all times.
The unit includes built-in adjustable compensators located at the front. By adjusting these with a non-magnetic screwdriver, you can zero out the deviation caused by the boat’s own magnetic signature for highly accurate navigation.
It features integrated 12V green NiteLight illumination. The green light is the industry standard for reducing eye fatigue and preserving night vision, making it the preferred choice for professional mariners.
The optically clear acrylic dome is UV-fortified to prevent cracking or yellowing. It is designed to withstand years of direct exposure to the sun and salt spray without losing clarity or structural integrity.
