Buying advice

When choosing a boat compass, consider the boat size, typical sailing conditions, and mounting options. For small craft, a compact deck mount or handheld works best. Offshore sailors need a gimballed compass with compensation. Look for features like night lighting, fluid damping, and temperature stability. Ensure the compass is suitable for your boat's material (ferrous or non-ferrous) to avoid interference.
