Yes, my NA-7DMKII housing is fitted with the Nauticam vacuum system. I had a third party vacuum system fitted to my old NA-7D housing before the Nauticam system became available. The Nauticam vacuum system is much better than the system fitted to the older housing, the Nauticam vacuum pump pulls the vacuum down much quicker, the vacuum can be released without having to reattach the pump and the warning light system gives a constant indication of the state of vacuum inside the housing. Happpiness is a nice green light shining on your housing.
Images are coming in the next few days.
