Hunting in the east (New Hampshire and now North Carolina) I've never needed a spotting scope. For my first trip to Colorado, I bought the above mentioned Leuplod Sequoia (Green Ring) 15x-45x X60mm. It is a good buy for the money. However, at higher magnifications, image clarity was distorted due to heat rise. I used them most at 20x - 25x and was able to locate game much quicker than with my 10X42 binos. After using itfor a week straight, I could see a tail or ear flicker from amile away

. I would recommend it if your limited to $350 or less. If I lived out West, I'd step up to Zeiss or an equivalent
