IRIS 50 – Hand Bearing Compass (Blue)
Brand: Nautos. Features: Graduation every 1°, field of view 20°, clearance 12°. Best for skippers who need precise, readily visible bearings on small to medium craft. This model offers a traditional hand-bearing layout with clear degree markings for quick readings. Caution: verify that the sighting window is clean to maintain accuracy in choppy seas.
Nautos IRIS 50 Hand Bearing Compass (Yellow)
Brand: Nautos. Features: IRIS 50 with both handbearing and traditional compass modes; Graduation every 1°, field of view 20°. Best for visibility in bright outdoor conditions due to the yellow color option. Choose this if you prefer a dual-mode instrument. Limitation: color choice may affect sediment or glare visibility in certain lighting.
Davis Instruments Illuminated Hand Bearing Compass
Brand: Davis Instruments. Features: Illuminated for night navigation. Best for mariners who operate at dusk or in low-light conditions and require a readable display without external lighting. Caution: illumination adds complexity; ensure the light source is reliable when visibility is critical.
Plastimo I-50 Iris 50 (Orange)
Brand: Nautos. Features: Plastimo 63599; Graduation every 1°; Field of view 20°; Clearance ±12°. Best for bright, outdoor use with a distinct orange housing for quick identification. Choose this to pair with other Plastimo or Iris line instruments. Limitation: color may not suit all vessel themes.
SUUNTO KB-20 Floating Hand Bearing Compass
Brand: SUUNTO. Features: Floating, lightweight; directional accuracy with a globally balanced needle and sighting tools. Best for marine professionals and outdoor enthusiasts who need a rugged, buoyant compass that remains readable when wet. Caution: floating design may be slightly less stable on rough seas compared to fixed mounting compasses.
Buying Guide: Key Considerations
- Purpose and use case: Choose a compass based on vessel size, typical seas, and whether you need night illumination.
- Readability: Look for clear graduation marks, field of view, and whether the sighting line is easy to align with landmarks.
- Durability: Consider housing materials, weather resistance, and whether the compass is sealed against splashes or salt exposure.
- Weight and portability: Light, floating, or compact designs are easier to handle on smaller boats or kayaks.
- Illumination: If night navigation is common, prefer models with reliable illumination and minimal battery requirements.
- Maintenance: Ensure the device is easy to clean, calibrate, and replace parts if needed.
What to Ask Before Buying
- Is a floating design important for my watercraft? If yes, consider SUUNTO KB-20 or similar models.
- Do I need night visibility? Davis Illuminated or similar illuminated compasses are ideal.
- How crucial is field of view and graduation granularity? Models with 1° graduation offer finer bearings.
- Will multiple color options help with visibility on my deck? Bright colors can reduce mis-reading in sunlight.
Quick Comparison Recap
- Best for small craft and precision: IRIS 50 (Blue) and IRIS 50 (Yellow)
- Better for night navigation: Davis Illuminated

- Best for rugged marine use: SUUNTO KB-20 Floating
Frequently Asked Questions
- What is a hand bearing compass used for? It helps determine a vessel’s bearing relative to a landmark or compass heading.
- Do all hand bearing compasses float? Not all; floating models are designed to stay buoyant if dropped overboard.
- Is illumination necessary for all sailors? Night navigation benefits from illumination; daytime use can rely on clear graduations.
- What does field of view mean on these devices? It describes the angular range you can sight through to read bearings clearly.
- How important is graduation precision? 1° graduations provide more accurate bearings, especially near fixed courses.
- Can I use these with digital navigation systems? They are designed for traditional compass bearing and sighting; combine with modern charts and GPS for best results.
