Hi I been a RD Since 84, and back in the day the specialty courses used to be given to you by your instructor on a paper card, with their Diver number and date of Completed course along with their instructor signature. I got my wallet wet and the specialty certification got destroyed, I was qualified in Deep Water, Under water navigation, Night Diving, Wreck Diving, Search and recovery, and ice diving, so I have my log book showing those dates when I was certified. How or where do I go to get my specialty courses confirmed. Where I got the certification was from a dive shop that is no longer in exsistance. I have over 200 hours of diving, and I am thinking I would like to apply for the Master diver certification. I agree for the Master you should at least 100 of logged dives, because everytime you dive gives you that much more experience.
