I have the Sea and Sea 45-degree. I like it very much. I believe it is identical to the INON. Must be same manufacturer as they look the same. Check to see if the mount s the same for the housing. My Sea and Sea has two small pins that fit into the plexiglass indents of the MDX housing.
For Sale is my trusty Sea & Sea MDX D810 Housing as I am moving up to the D850.
Housing is a couple years old and in very good condition. It has never leaked nor been flooded in the 75 dives I've used it on. It has been carefully cared for.
$2500 includes the housing and handles plus used and unused "O" rings
Will consider selling the D810 camera and optical flash synch also
Thank you for your interest.
