The 15-40x50 Colorado Spotting Scope is a lightweight zoom spotting scope useful for bird watching and spotting at the target range. Multicoated glass and a BK-7 Porro prism transmit bright contrast-rich images throughout the entire zoom range. An included mini tripod is foldable and convenient for terrain navigation and nature observation on-the-go
I use it mainly for checking up the target when I shoot pellet guns in my basement. 23' range. I hope it will also work as well outside during summer time when I extend the distance to my target to 100' The only bad thing about the product is this little tripod. So far it works, but it does not look like it will last long.
