Im looking to order a CDS for my VX-6. My question is about how accurate do I need to be for the elevation? I am hunting CO this year and the elevation range is anywhere from 7500-10500 ft (depending on snow). I also hunt in southwest WA were I live and the elevation here where I usually hunt is 1500-4000 ft. Im guessing the best thing to do would be get one for each location, but with a wide range of elevation is it better to error on the low side or high side??? Any thoughts or advice would be greatly appreciated.
