Tuesday, November 17, 2009. What is the Open Water course? The Open Water course is the basic scuba diving certification course taught by all certification agencies. There are small differences in course content between agencies, but they all cover the same basic skills and knowledge you will need to know as an independent diver. You should float at eye level. Some people float at forehead level or chin leve.
