I had gotten a very good ebay deal on the old 7x50's big older version (1500yd range), they did work very well, heavy so the stayed in the rig or in range bag, glass was a bit dark. Used them for 5 years
& then found another ebay deal ($300) on newer set 7x40 (1500yd range also) (have ranged houses at 1680), much more compact, bit lighter, better glass
less than 1/2 of any other deals
I do run older Leica 1200 rangemaster monocular for carry/hunting , but the newcons are easier to use/range, field of view - the whole bino thing over mono
