I知 planning a South Dakota prairie dog hunt in June and have just begun dialing in my new model 12 FV in 204R. Seeing as how the 204 will reach out quite a bit further than my 17 hmr, I知 thinking a range finder purchase would be in order. It seems like the selection of these tools is mind numbing as are the number of features. I知 looking for some insight from the prairie dog exterminators here.
