We recently, moved and during the down sizing process my wife thru out all my dive logs. My books included, Salvage Diver, Rescue Diver, Cave Diver, Cavern Diver, Equipment Specialist and three proficienty/renews. The real kick in the pants is my dive instructor died. Most of my speciality certificates is thru MDEA. I have over 2,000 hours logged! When, I was in college, I needed additional credit hours. I needed a refresher course and opted not to pay the $150.00 renewal card but got my log book signed for the same. I had 500 more hours logged than my instructor. I somehow got recuited in teaching the class. I was honored and helped in any way. The fact is, The only certification I own is my basic card and advanced card. What do I do now?
