CSI has a full service dive shop here in Columbus, and then travels to Ohio quarries for open water certifications and weekend fun dives. In addition, they do trips to other US and Carribean dive sites. I recently earned my Advanced Open Water PADI certification through Columbus Scuba. It was a fantastic experience. Andy, Melissa, and the whole team did a great job of making the process easy, safe, and comfortable. The rental equipment that we used was all in good condition and reasonably priced. For the dives at Gilboa, the crew was well organized, patient, safe, and fun. While Andy led the training, there were so many other divemasters and instructors that it was a 2 students to one pro in the water, which is perfect. I’m looking forward to diving with the CSI team again and, hopefully, taking more courses.
