I currently own the Leupold RX1000. I bought this for a bowhunting range finder and in that capacity have been very satisfied. The problem is that when shooting my 7mm Sendero at distance I have a hard time getting a reading on anything over about 475 yards away. Yesterday I was able to get a brief hit at 798. I was trying to range on a house , large cedar tree and several camper trailers. It only hit one range but I could not get it to repeat the range. Right now I am having to step range from one point to another to get to where I want to shoot too. What type of surface does an object need to get a good reflection? If I upgrade to a Leica or similar range finder will I have the same problem?
