What the heck is this? It is supposed to have a probe thingy and a foot switch - I have neither but I have the 500H head on my L1200 Durst. Has anyone used one of these? Where can I find a probe for it?

Incidentally, why does beseler 45 have a motorized drive? Will moving the darn head up and down about 10 inches really burn up so much muscle energy?
