All this gear is used -- mostly by me. All of the regulators should (REALLY DO IT) be serviced prior to being used. The HOG regulators (1st and 2nd stages) can be serviced by anyone who has taken the HOG service class -- kits can be purchased from Amazon and other online stores.
I am a PADI Instructor who has just decided to retire. My late wife and I accumulated a LOT of gear over the years and it is time for most of it to go. If you don't like the asking price, make me an offer.
have multiple HOG regs (1st and 2nd) and Mk 2s. [all sold]
I'm in Olympia, Washington and all prices are FOB my house.
