not for jumping
Having flanged myself out of a perfectly good airplane, camera in hand, a few times, I can tell you a camera with sharp corners and things that protrude out of the body, like that knob and the viewfinder thingey, is not what you want.
One could, I suppose build this thing into fiberglas helmet mount but that would involve yet another structure.
Fascinating stuff but I have no idea what it is for.
Of course, here in the States, our knowledge of the RCMP is limited to Dudley Do-Right.
