Ritchie · B-51G · Explorer Series

Your course, without room for error.

70 mm direct-reading dial. DirectiveForce magnets that lock onto your heading instantly. A bracket that adjusts by hand. The B-51G is the compass you install in minutes and forget about — because it never fails.

Sport fishing yacht at sunset — the B-51G in its element as the sun goes down.

Precision

The heading is read, not interpreted.

70 mm dial with high-contrast numbers. Direct reading eliminates ambiguity: you see the exact degree without calculating, without guessing. DirectiveForce magnets lock onto the heading in fractions of a second — no oscillation, no doubt.

Night

3:00 AM. The dial is lit.

Internal green illumination doesn't rely on batteries or the console. It is passive, constant, and always ready. When everything else shuts down, the B-51G is still there.

Installation

Bracket, thumbscrews, ready.

No drilling, no sealant, no waiting for anything to cure. The bracket mounts in minutes and adjusts by hand. The thumbscrews allow you to reorient the compass without tools. Integrated compensators to calibrate magnetic deviation on-site.
