My father in law gifted me a nice Mk25/S600 reg setup but his BCD was way too big for my son. I am looking for a size M or maybe L Scubapro BCD with an air2 so I don’t have to go buy an octo, inflator hose and separate BCD. Hoping to find something that doesn’t break the bank as this is for my son who is heading off to the airforce soon.
