OK...now I have seen it all...
And, I suppose, a strong piece of rope/cable is supplied with each of these, to keep the quarry from moving while you are playing with the buttons and trying to remember which does what!!
Saw a movie many years ago where a guy had a digital scope on his rifle - and it worked to the same effect, just had much more buttons.
Only other thing that still needed on the scope is a built in rangefinder.
Will have to start looking at changing the FT rules ...
Seems the future is here.
