Marine Compasses Comparison Chart

Things to Consider Before Buying a Marine Compass

1. Mounting Style

Choose a mount that fits your vessel’s layout.

• Flush mount: Sleek, integrated look for dashboards.
• Bracket mount: Adjustable viewing angle, great for smaller boats.
• Surface mount: Ideal for kayaks, paddleboards, or tight spaces.

2. Dial Size & Visibility

Larger dials (3″+) are easier to read, especially in motion or poor lighting. Compact dials save space but may limit readability from a distance.

3. Illumination

If you boat during early mornings, evenings, or in fog, internal illumination is a must. Green night lighting is common and easy on the eyes.

4. Dampening & Stability

Higher-end compasses use PowerDamp or jewel pivot systems to prevent needle bounce, which is especially helpful in choppy conditions or at high speeds.

5. Weather Resistance

Look for UV-resistant housings and sealed designs that prevent fogging, cracking, or salt corrosion.

6. Deviation Compensation

Built-in compensators allow fine-tuning if magnetic interference affects compass accuracy on your boat.
