How to get quality camera accessories (protection case for diving)

Hi,

sadly gopro basically ended their support of the older camera models, which might still be good and useful.

I was looking for the standard gopro hero 4 case and the backpac backdoor. The orignial parts support diving to the depth of 40m.

There are still a lot of thirdparty cases available, but often you see them leaking water and damaging the camera.

If you know where to get new original stock or equal parts in the eu (germany), please help me out.

Thank you

Greetings Sebastian
