Padi vs Nuai

Choosing a certification type, PADI vs. NAUI

The basic diving certification offered by PADI is Open Water Diver, and the basic certification offered by NAUI is Scuba Diver.  From what I can find online and discussions with several dive shops the two are considered equivalent courses and accepted by most dive shops and locations globally.

As I did more research I learned there are some differences. For example NAUI requires students to learn the basics of rescuing an unconscious diver where PADI does not. On the other hand PADI requires no mask underwater breathing which NAUI does not.

PADI instructors follow a fairly strict, regimented program when teaching their courses, while NAUI instructors are allowed to be more flexible and are encouraged to exceed standards. What this means to me is that NAUI has the potential to be more thorough but its instructor dependent. PADI however is likely more consistent regardless of instructor.

As a whole, it appears that the two certifications are more similar than they are different. Since as I learned PADI was started by a NAUI instructor (Ralph Erickson) with an equipment salesman (John Cronin) it makes sense that they are very similar. So given that they are similar how do you choose?

For me I selected PADI because I am a strong believer in referrals from people I know and trust. A co-worker of mine who is an avid diver suggested a particular dive shop she frequents and respects. Given that there are several closer options (literally across the street) and yet she still suggested a dive shop over an hour from where we live I took her advice and decided to check them out.
