This may sound dtupid but I am looking to sell my Ziess 10x45 RF binos and replace them with the Vortex. If I could finnd some Lieca Geovids at the price of the Fury HD 5000's I would gladly go that way. What I would like to know is how far can the Furys range deer and other animals. How good is the glass for clairity and brightness at dusk. Any other info would be great as well thanks in advance.
