You might want to call Doug or Joel at
www.cameralandny.com real good guys to deal with and they are sponsers on several hunt sitesalso Minox dealers.
I have a pair of Swaovski 8.5x42 EL because the 10 x 42 were hard to hold steady and if you have to really take a good look at something 500 to 1000 yards off you really need the spotting scope IMO.
