I have a Scubapro regulator that is part of the parts-for-life program. The 1st stage is a Mk25 that was an upgrade from the 1973 Mk7. The 2nd stage is the original -109 that is unbalanced and was recently serviced at the factory.
My deep cold-water diving, instructor is urging me to get a balanced second stage like the G250v. I was wondering if I could have Scubapro or an authorized dealer convert the -109 to balanced with the appropriate poppet. The parts seem difficult to obtain.
If I were able to have the -109 converted to a balanced, would this provide performance similar to the G250v? Thanks, Ken.
