I have never owned a rangefinder, but I feel like it would be a good piece of equipment to have for taking the long shots until I can judge them myself. I currently have the available space to take shots out to 600 yards on a friends property. While doing some research I found a Bushnell Pro 1600 on sale. I cant imagine I will ever need the 1600 yard ranging, but at least its there if I need it. My biggest issues that concerns me is that it is factory refurbished. it's currently on sale for $229. A new unit goes for roughly $100-150 more. I'm not 100% sure what all I should be looking for, and if this is worth it. Can anyone hand out some pointers that they use when purchasing and using a range finder?
