Hello, I have been diving a long time, NAUI certification in the late '70s. I'm a PADI Master Instructor, stopped teaching a couple of years ago. I started photography with my Dad's Nikonos II and flashbulbs. I saw one in a museum a while back. Right now I have a Nikon D300, Sea & Sea YS-250 strobes and a Sea & Sea housing. I am looking for a new system, something a little more compact. Hauling the D300 and the strobes on a kayak is kind of a pain. --clark
