John NG reported at Goosiam that he found a GH4 camera wrapped in a Nauticam housing. The camera got spotted in a small hole at 18.5 meter under the water. John was quite surprised to find out that the housing resisted for more than three months under the sea and the GH4 camera was still working fine!
He contacted the Nauticam company and they got in contact with the camera owner by tracking back the serial number from the case.
Shows how well resistant those Nauticam cases are. Chapeau!
