My new range finder arrived today. I quickly ranged a spruce tree on the second ridge behind my house,591 yds. I'll be darned. I estimated the range, using my IOR MP8 reticle on an elk, at about 700. I drove down the hill a bit to try it out on real live elk. Wow! this unit is fast. It ranged elk from 490 - 515 yds in just a couple seconds. It is in a different class than the Newcon 1500 I bought, and promptly returned.
