I played with one at the ATA show........ wow.
Your first reaction to trying it is like watching a David Blaine magic trick.[:-]
after 10 seconds with it you forget all about the price tag and you are rationalizing ways to pay for it.........like what's the going rate for a kidney? You only need one of those right?

I'm serious, it's impressive.......if I had the time to devote to open class 3D shooting I would have to find a way.
The sight works with internal prisms, and instead of your scope sliding up and down the length of a slide bar, the IMAGE within the Spot-Hogg scope moves, and the scope and pin stay stationary.
Way too cool for school.[8D]
When you consider the price of a top of the line sight bar and a high end scope, the price of this sight doesn't seem tooooooooo crazy. Besides this thing is NOT your everyday scope.
Get one in your hands and you'll see.
