Hello from a deeper blue newbie - I was certified as a NAUI/PADI instructor in Okinawa in 1970 and was active as an instructor, mostly in Kentucky, until about 1977 - Obviously, I'm an aging but still enthusiastic diver - I found the deeper blue forum while doing research on the Okinawa Reef Rovers - it was mentioned in a post several years ago and I would like to make contact with anyone interested - Since I've found the forum, I will be back
