Question

How do you get a C-card for scuba?

Answer 1

You have to take and pass an approved scuba course.

Courses vary based on the certifying agency.  PADI's Open Water Diver Course is the most common.  It can be done as a "resort course", which is completed in a couple days, or a traditional class which would meet twice a week for 4 weeks.  Then you have 4 check-out dives and a written final exam.  Pass and you get your C-card.

Check PADI's website for dive shops that teach in your area.
