Buying Guide
What mounting type should you choose? Flush mounts save space and offer a clean helm look, while dash-mounted or bracket-mounted options provide flexibility for positioning and angle. Consider your cockpit size, seating layout, and whether you need a glare-resistant or night-illuminated model.
Is night visibility important? If you operate at dawn, dusk, or night, select models with built-in lighting (NiteVu or incandescent) to ensure legibility in low light.
What reading clarity do you need? Direct-read dials simplify direction interpretation; smaller dials save space but require close attention. A larger dial improves readability from several helm positions but may be bulkier for compact boats.
How important is compensation for deviation? Look for built-in compensators on models that claim easy deviation adjustments. This helps maintain accurate heading without external tools.
What materials matter? ABS plastic housings are common for budget-friendly options and resist corrosion in marine environments. Glass or acrylic covers protect the dial but can glare in bright sun; consider glare control features if you frequently sail in sunny conditions.
FAQ

- Do compasses need calibration? Some include compensators for deviation; others may require periodic calibration depending on vessel interference.
- Which is better for night use? Models with built-in green NiteVu or incandescent lighting offer the best readability at night.
- Can I mount a compass on a dashboard? Yes, many models are designed for dash, flush, or surface mounting, depending on your helm layout.
