I have a laminated IANTD Deep Air Diver certification card #467, dated April 7, 1996 that was issued to me by John S. Walker, Instructor. Don't mean to "give you hives", Johnny me boy, but why was I never told the card is now invalid by either you or IANTD? So now what's the maximum 21% depth limit? And why were we in harms way at 180 fsw in the spring of '96?
