I have a Cabela's Intesity 1600 rangefinder that seemed to be good quality and has a pretty long range for the money but it gave me some issues in Wyoming this year. I was trying to range a group of antelope bedded on a slope. I couldn't get a range to save my life. I was able to get a range on a cow that was further down the slope to the left but that information was only so useful due to not knowing how far the cow was from the antelope and at rough distance of 4-450 yards (based on the range I got off the cow and comparing distance visually) I was not comfortable "guestimating" for that shot. I think the solid background of sage had something to do with the troubles as it had no problem on the side of the giant cow. Do I need to spring for a more expensive rangefinder (I'd rather not. The one I have isn't broken or anything) or would the thick sage brush backdrop give any device trouble at that range? I had a similar struggle with a few lopes bedded against a wheat field slope but was eventually able to get a range due to them being closer and I was able to hold JUST steady enough on the body to get a reading.
