I'm still trying to decide what I want to buy for my first scuba setup. I would eventually like to try some tech diving but that might be a year or two away. Probably wrecks and deep dives. Not so sure about cave. I was thinking about getting a BP/W system and using a single tank adapter. This way I could use it for sport diving and not have to buy another BC someday when I try tech. Is it possible to get a regulator and computer that would work for sport and tech diving? From what I have read that would mean buying a regulator with a DIN valve, balanced first and second stage and sealed. I may just get the BC/W setup and a computer and rent the rest of the gear for awhile.
