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

Description

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.

Mounting and Compensation Considerations

Cutting a 6.25-inch hole for this Ritchie marine compass is a major step, so location planning is paramount. It must be mounted on the vessel’s centerline in a spot with minimal magnetic disturbance. Before cutting, sweep the area with a handheld compass to identify any hidden magnetic fields. After installation, a full compensation or “swing” of the compass is not just recommended; it is mandatory to ensure the instrument is accurate and trustworthy for navigation.

Before Ordering the Ritchie FB-500 Globemaster Commercial Marine Compass

Before you purchase, create a 6.25-inch template and physically place it on your console to confirm you have adequate space and clearance for the compass body underneath. Ensure you have a switched 12V power source nearby for the illumination. Plan for the professional compensation procedure that will be required after installation to make this instrument truly navigation-ready.
