I know that rangefinders have been discussed a lot and I've researched the threads. I know the 1600B is the best of the 3, but also the most expensive. I'm trying to decide if its worth the $800 for the 1600B versus $600 for the 1000-R versus $379 for the ranger 1000. I'm new to long range hunting and I think that 500 yards is going to be my max range, for now. For now most shots will not be on very mountainous conditions, but that could change in the future. But I don't want to be cents foolish and buy a rangefinder that I will want to replace in a couple of years as my ability with my rifle increases. Can you help me decide???
