I was SCUBA
certified in the late 70's by an NASDS shop and instructor. At that time I got my C card and a microfilm record
of my cert.
Supposedly, if I lost
my card, the film would be my documentation
to get a replacement. Well, I lost
the c card and now, 30 +
years later, NASDS doesn't exist and no one seems to know anything about the micro film.
Anyone have a suggestion?
