We charge the same regardless how many students are in the class and regardless how long it takes. When you sign up for the Open Water Course, you decide whether you want PADI, PDIC, SEI, or CMAS. The only requirements we have are, you must have your own Mask, Fins, and Snorkel, (You can pre-own, borrow, rent, or buy, and if you choose to buy then you can buy from anywhere, you don't have to buy from us). If we have a wet suit in stock that is sufficient for the water temperature at that given time, then we supply it at no extra cost. Our Open Water classes include all training material, all pool fees, all gear except mask, fins, and snorkel, and free check out dives, providing that they are completed in our local lake. If a student decides to bring a friend, for each friend that signs up for the course, the first student will get 10% discount on their class. After they have 10 friends sign up with them, the first student's class is free. Most choose to distribute the 10% over all 10 friends. As of right now, our current Open Water Course is $349.99.
With all this being said, this is not for a certification. This is for the training. Students have to earn the certification. We don't put a price on that, the student decides how much they want to invest into earning the certification (no money transfer of course, they get out of diving what they put into diving).
