I have a NA-D700 Nauticam Housing for sale.
The housing is in excellent condition. I have used the housing only a week ago to image humpback whales in it worked flawlessly. The system has an audible leak alarm which is in good working order. All of the buttons and springs are in excellent condition and the unit feels like new when operating. Spring tensions such as the shutter release have a perfect feel. The unit has been stored in a dehumidifying cabinet when not in use and always had a thorough fresh water clean. Most of the time I have used this housing with surface animals so it has not seen many deep dives.
The asking price is $2000 AUS.
Ask any questions and I will answer as quick as possible. More pictures to come.
