You can see the boom mount in these pics I posted on this thread - they are hard to see too.
You have to scroll or do as I do, right click - save as to your desktop/folder and then open it with your favorite picture viewer so you can see the whole thing/zoom in and out etc.

Great for foot'n or for teaching anyone to ski - they can learn what it is supposed to feel like before they learn controlling the rope.
I'll email you a pic of me on it, that should give you an idea.
