I hunt open fields between woods in the Midwest with a 30-06 or a 6.5X55, both bolt action and scoped(Leupold & Zeiss) and both are accurate arms at a distance. I also crossbow hunt. I don't feel that I need a long range(expensive) range finder because I limit my shots to less then 400 yards and usually to 300 or less. The rifles are zeroed in at 250 and 200 yards so only the longer shots require a rangefinder as well as the crossbow. I use the lower end Leupold 650 yard rangefinder, it costs less then $150 on one of the popular bidding sites and seems to work very well. I have tracked trucks out to over 800 yards with it and it seems to be accurate for the distances that I use it for. Why pay more when this serves the purpose within the range of 400 yards?
