Coastal and Celestial Navigation Courses and Tools

[Coolruns]

I am considering both ASA 105 Coastal Navigation and ASA 107 Celestial Navigation training through the winter months.

If you have taken these, what are your opinions on them?

Also, I plan to buy navigation tools, including a sextant in the next few months.

Can you recommend tools for the cruising sailor?
- parallel rule
- Mark 25 sextant
- dividers

I appreciate your thoughts.

Best Regards.
