Hi, I am looking into the development of SCUBA regulator innovations and their history. Does anybody know the first brand or reg to offer or evolve to a balanced system? Otherwise some examples of older balanced regulators would be cool.
Thank you.
My new drysuit came with a Heser p-valve. I'm not going to need it until I will start doing longer and deeper dives, but I will use my drysuit tomorrow without connecting the p-valve and I'm not clear on wether it should stay open or closed, or will have to be opened/closed during the dive...
Excellent condition all "satin" chrome balanced adjustable. European only release marketed with MK 10 as a "Dual Balanced" regulator. New diaphram, S-wing poppet, and chromed orifice. Breathes very nicely.
