I am on eof the lucky ones. I have beeen using this product since Christian came up with his first prototype. It has helped me take a 318" & 327" bull elk with my bow and a couple of unfortunate javalina. I was with Christian when he and I had an opportunity at a 380"++ (would have booked in B&C for sure) bull elk, but neither of us had quick access to our range finders. Turned out, after the bull had walked off, he was much closer than I had thought and well within both of our abilities. Both uf us came home with considerably smaller (but still respectable) elk. I have forgot My Range Snap a couple of times and it makes uneasy when I do. It is worth it's weight in gold when that trophy animal shows up unexpectadly.
