I am selling a SONY RX100IV and Nauticam RX100IV housing set, both in excellent condition. Them have been through around 80 dives, never leek. The RX100IV is my dedicated UW camera, so almost live at the housing with no dings and dentss.
The Pro housing set comes with the dual handles and a shutter release extender. However, the shutter release extender is barely usable now.
Selling the whole set at 1100 USD. Located at Seattle WA. PM if you are interested.
