Selecting a marine magnetic compass:

1. Size: The size of the compass should be appropriate for the size of the vessel and the size of the compass rose. A larger compass is generally easier to read, but it may not fit in smaller vessels or spaces.

2. Type of vessel: The type of vessel can affect the type of compass needed. For example, a high-speed powerboat may require a more stable and accurate compass than a sailboat, which may be more affected by wind and sea conditions.

3. Navigation requirements: The navigation requirements of the voyage should also be taken into account. If the voyage is in an area with high magnetic interference or variation, a compass with compensation or correction capabilities may be needed.

4. Accuracy: The accuracy of the compass is critical for safe navigation. Look for a compass with a high level of accuracy, stability, and repeatability.

5. Ease of installation: The compass should be easy to install and maintain. Consider factors such as the mounting location, ease of adjustment, and compatibility with other onboard systems.

6. Lighting: Look for a compass with adequate lighting, such as built-in illumination or compatibility with external lighting systems. This is important for night-time navigation.

7. Certification: The compass should be certified by an appropriate authority, such as the International Maritime Organization (IMO) or the American Boat and Yacht Council (ABYC), to ensure compliance with safety and performance standards.
