Is the HF-743 a flush mount or surface mount compass?

Yes, it includes 12V green night lighting so the dial remains legible in low-light or nighttime conditions.

Can I adjust for local magnetic deviation with this compass?

Yes, the HF-743 has built-in compensators that allow correction for magnetic deviation without needing additional external hardware.

What is the overall diameter of the HF-743 compass?

The compass measures approximately 5.2 inches in overall diameter, while the dial itself is 3-3/4 inches (94mm).

Which color should I choose, Black or White?

Choose the color that matches your dash or console: the Black Combi Dial version suits darker helm layouts, while the White version suits lighter or classic-styled consoles. Both have identical dial size, mounting, lighting, and construction.

What is the compass housing made of?

The HF-743 housing is made of stainless steel for corrosion resistance in marine environments.

What warranty comes with the HF-743?

The Ritchie HF-743 is backed by a 5-year warranty.

$323.57

The Ritchie Helmsman HF-743 is a 3-3/4 inch flush mount marine compass built for helm stations where reliable, easy-to-read heading information matters. It uses a Combi dial design, letting you read the heading both from directly above (flat-card view) and from the front of the boat (direct-reading view), so the compass works whether you are seated or standing at the wheel. Built-in compensators let you correct for local magnetic deviation caused by nearby electronics or metal without buying extra hardware, and 12V green night lighting keeps the dial legible after dark. The stainless steel housing is finished in either black or white to match your dash or console.
