The one thing I can tell you for sure is that if you have to pick a company to deal with and that stands behind their product it is Burris. I have used there scopes, binocs, and spotting scopes for as long as I have been hunting. Last year I went on a Mule Deer hunt in CO, and left my 10x50 signature series binocs in this guys pickup that i didn't know. To make a long story short, He trashed my binocs. When I finally got them back the lenses were scratched and full of dirt. The lefttelescoping eye piece was broken off. Just Trashed. I called Burris and told them what happened. There service dep. told me to send them in and they would look at them. I'm not kidding, 10 days later I got a package and it was my binocs. They rebuilt my binocs with everything new except the outer cover, and the greatest part, They did it all for FREE. There a small company in Greeley, CO and know how to take care of the customers!!
