PADI is the largest most widely recognized SCUBA certification agency in the world. PADI has the widest network and most dive shops and resorts around the world are PADI. If you loose your card or want more training you'll always be able to find PADI.

All Scuba Certification agencies use the same standards and teach about the same scuba certification course. Just like a learning to drive a car, all driving schools will teach you the same rules. Some scuba instructors claim their agency is better and their competition is bad, but in fact we are all about the same. Find an instructor you like and be happy.

Scuba as a recreation sport should be fun relaxing and safe.
