Ritchie FB-500 Globemaster Compass – Flush Mount – Black – 12V – 5 Degree Card

Need a massive, professional-grade compass for your flush-mount console? The Ritchie FB-500 Globemaster is built for the job. This black, commercial-duty compass features a huge 5.0-inch card with clear 5-degree markings, designed to be read from a distance on a large vessel’s bridge. It uses a direct-reading format, so the number at the top is your true heading. The heart of the compass is a scientifically matched gimbal system, a sapphire jewel bearing, and a hardened steel pivot, all working to keep the card stable and responsive.

This instrument is made to live on the water, with a 100% weatherproof housing that seals out moisture and withstands temperatures from -20°C to 60°C. It comes standard with 12V internal night lighting for 24/7 operations. To handle the unique magnetic fields of any vessel, it includes powerful built-in compensators for precise deviation adjustments. Installing this beast requires a significant 6.25-inch cutout, making it a permanent and commanding feature on any professional helm.

Helm Use and Readability

The sheer size of the FB-500’s 5.0-inch dial makes it effortless to read from the helm. You do not need to lean in or squint; the heading is clear and unmistakable. This is critical on a busy bridge where the captain’s attention is divided. The direct-reading layout is intuitive for steering. At night, the internal lighting creates a strong, even glow across the dial, ensuring the numbers are just as readable as they are during the day.
