What is the best way to clean and maintain the plotter?

Clean the plotter with a damp, soft cloth to remove dust and debris. Avoid using harsh chemicals. Store the plotter in a protective case to prevent damage when not in use.

Can the plotter be used with all types of nautical charts?

The Davis 064 Course Plotter is compatible with most standard nautical charts. Ensure the chart scale matches the plotter's scale for accurate plotting.

How do I troubleshoot if the plotter is not aligning correctly?

Check for debris or damage around the pivot point. Verify that the chart is laid flat. Ensure the plotter itself is not warped or damaged. Recalibrate if necessary.

What steps should I follow to plot a course?

To plot a course, place the plotter on the chart, align the desired course with the compass rose, and mark the course using the plotter's edge. Adjust and verify alignment as needed.

Is the plotter affected by temperature or humidity changes?

Extreme temperatures or high humidity may affect the plotter's materials over time. Store in a controlled environment to ensure longevity.

What should I do if the plotter's markings wear off?

If markings wear off, they can often be restored using a fine-tip permanent marker. Replacements may be needed if the plotter is extensively worn.

How can I check if the plotter is still accurate after extensive use?

To check accuracy, perform a test alignment with a known reference on a chart. If discrepancies are found, recalibrate and verify the structural integrity of the plotter.
