I`ve got a 15 x 30 Leupold spotting scope that I love. The optical lense is so much larger than anything else I`ve see. It give the scope a field of view 3 to 4 times that of other scopes of the same power, but it is a Leupold scope and not Wind River. I do have a pair of 8 x 42 Wind River bino`s though and I have never found any other brand that would come close to them for the money.
