Was wondering what the general consenus is. My regulator is a Conshelf SE2 circa 1980's. It's always preformed well for me so I hate to part with it. Recently I decided to convert to HP steel 100's. Now I am faced with whether to put a DIN adapter on my current regulator or bite the bullet and invest in a new DIN regulator and keep the SE2 as a spare for rentals in the Carribean. I dive mostly 90 ft and above in warm water but occasionally below 100 ft. All of my local diving is Nitrox these days. Any advise/comments appreciated. If you think I shoud move on to a new reg let me know what would be a good choice. Also if I added the DIN adapter what would be my best course to convert back to yoke when on travel?
