The problem with a certification card for any diving skill is lack of mandatory periodic recertifications and no requirement for minimal diving hours using the skill in order to maintain certification- assumming you became proficient after taking the original course and receiving original card. I could get a tri-mix certification today, not dive for three years, and the card still says I'm a tri-mix certified diver. Dive operators ought to ask for a card and a log book along with an FBI affidavit of competency. Rod
