Twenty-five of the past thirty-two years I was a wildlife officer and the three pieces of equipment I relied on entirely were, in descending order of importance, my truck, binoculars and spotting scope. That being said, rarely, did I ever leave the truck with the spotting scope..an excellent pair of bino's were all I needed. During my career I used 7x35's, 7x50's, 8x32's, 8x42's, and 10x50's and now believe the best for Colorado hunting are 8x42's. I own and sometimes use my Leupold 20x fixed spotting scope in our eastern prairie country but have found that I leave it at home when hunting the mountains. Use your money on excellent hunting boots instead.
