I was very happy with this rangefinder when I was just playing with it indoors, but when I took it hunting I ran into problems. The first day was a bit foggy and I realized that all the routes were too short. I never noticed that with my Leupold, but I thought it just happened. Took the rangefinder out on this cold morning, all the optics are cloudy and now the reading is way too far away, about twice what it looks to me. Unfortunately, I cannot recommend this as it does not work in many weather conditions.
