The open water diver course at big blue was a great experience. The instructors are skilled and a lot of fun. They make you feel like youre part of a family while your at big blue. You have your own equipment for three days and they learn you how to use it and take care of it. The guides are comforting underwater (also give u extra attention if you need it, and i did) and guide u through amazing divesites. So...... Go with big blue!
