Why do you say this?
It is hearing people say that they "have PADI" as a shorthand for being a certified diver. Like using "Xerox" for "photocopy". Quite a marketing accomplishment, if you ask me.

Why do you say this?
So you recommend ignoring the professionals and only listening to the amateurs?
How are Navy diver professionals and folks who teach diving for living amateurs?
What has commercial and saturation diving have to do with recreatinal repetitive NDL diving?.
How many procedures from the Navy manual are applicable to recreational divers?
.... Navy Divers are the professionals while scuba instructor is just another amateur certification.....
..... You were the one implying the US Navy Dive Manual was not appropriate recreational divers.....
....You have no clue do you?

The Navy stopped making any work on the dive tables back in the 1950s and ALL the work on tables for recreational diving, including experimentation for recreational tables, has been done by private entities (mainly PADI) - every other agency contribution to the dive tables has been to add conservatism to the 1950s tables andthen make revisions to bring them in line with the current state of private research.
Moreover, in the NAVY manual there is nothing about teaching diving and certainly nothing about learning methodologies.

demed on Scuba Board

There is a guy on Scuba Board with the handle "demed" who claims to be a master instructor that works for you. He is using your logo on his profile as well. He does not seem to know as much about diving as an instructor should, never mind a master instructor. Is this guy really working with you as an instructor? If so why would you hire someone like this?
This message was submitted from your website contact form:
1. USN and NEDU have put out several table changes in recent years, including changes to ascent rates and TBT in 2008, as well as some dealing with tactical rebreather and a rewrite of SCUBA.
2. Not even sure where you get this stuff, certainly not from PADI since they have never taken this much credit. For example, with regard to RDP, in 1988 Ray Rodgers took the 1956 Tables, incorporated M values and other techniques to provide for additional conservatism turning them over to DSAT for testing. Certainly nowhere near the work and research of either Weinke (RGBM, used by NAUI since 1999) or Yount (VPM, 1991), and you somehow totally skip over Buhlmann (1983/4).
3. I have yet to see anything in the PADI OW student material (including the latest released last year) that discusses teaching or learning methodologies. That information is found in the OWSDI manual, where they actually talk about how to teach the course. I don't know why you would expect the USN Diving manual, a student manual and reference manual, to be any different.
this is what makes the PADI system accessible and appreciated by students worldwide, while the USN sucks big time, just try to use it on a 12 year old next time.
