There are boatloads of scuba diving training providers out there, so how do you choose one? A good rule of thumb is to go with one of the big three—PADI, NAUI or SSI. If you get your basic scuba diving certification from any of these organizations, you’ll acquire the same knowledge and skills and be allowed to dive anywhere in the world. Course options range from open water diving to professional instructor training, including specialty courses like night, nitrox and wreck diving.
PADI and others now offer online versions of the classroom-based portions of certification courses online. E-learning may be a good option for prospective divers who want to learn at their own pace as well as already certified divers looking to refresh their scuba diving knowledge and theory. Of course, this may not be a good option if math and science are not your strong suits, or if you learn best from an in-person instructor who can answer your questions on the spot.
