I have a nauticam housing with a Nikon D850 and a Nexus acrylic dome with nauticam adapter and 3 mm extension on it. It is not one of the small domes. I also have the nauticam straight viewfinder which ads a tremendous amount of weight to the back of the housing but I love that viewfinder. Am wondering what solution others have found for weighting the front dome so that the rig is not so back heavy/dome up. I'm experimenting in a large tub with a 1 lb. ankle weight strapped to the port extension. Have heard some talk of stick on lead car wheel weights stuck on the shade. Not sure how to safely do additional flotation toward the back of the camera that wouldn't get in the way as a different option. What has been the best solution for the gurus out there?
