These are great scopes for the money, and for predator calling/shooting in cover. I tested one years ago and it was really nice to be able to range and already be on target. In the brush, ranging with binos or range finder then trying to re-acquire and dope takes time. The benefit of this scope is once the animal is in the reticle, one push of the button and you not only have range, but you also have your aim point illuminated so it is place dot and fire. Glass on the one I tested 10 years ago was decent for the price point as well
