To have a free specialty course, all you have to do is simply recommend three people for a full diving course with Diving With Bubbles.  For each person that takes (& pays in full) a diving course* a star will be placed over a  vacant space of your choice and stamped in your card. A free specialty course will only be vailed after  all three star´s have been filled. There is no  time limit for you to do this, but the more you recommend the more you get, for FREE!
