Discontinued means we will no longer sell the V32 1st stage coupled w/ the Ice 2nd stage (blue cover / matte finish on the metal body). The replacement model is the new "V32 Proton Metal". The Proton Ice Extreme is a completely different reg. It is still a V32 1st stage although it comes with a CWD kit (enviornmental seal) preassembled. The second stage is still metal (nickel plated brass) but has one more coating on the outside, inside, and all exposed working parts. This coating is a technoflouropolymer (teflon). This coating prevents ice from adhering to any part of the regulator. Ice crystals slip off. The Ice Extreme has been approved and put on the Navy ANU list. The only single reg that is on the list qualifying for both cold and warm water (no small feat).
As for the parts replacemtent warranty on the ice. Should the purchaser buy the Proton Ice from an authroized retailer, then yes the regulator qualifies for free service parts replacement.
Parts will be available for the Proton Ice indefinitely. The parts are the same in the V32 Proton Metal and other Mares regulators.
I think you may be slightly mislead on the "pulling/ discontinued parts for discontinued regs". We are still providing "service" parts for old, old, old, Mares regulators. Although in the past we were not the best at having them in stock. This has dramatically improved and is only getting better. The new parts replacement policy is a direct extension of our commitment to be one of the best.
