Scuba Pro doesn't offer an online manual for their regs like most companies do. They don't even have an email address listed. What's up with that? I'm looking especially for mk25/s600 but I also need one for my octo, bc and guage. I live in korea and my lds can't seem to find me english manuals. I'm starting to wonder if this company will even sell me a manual. They don't seem very keen on people contacting them.
