I have a pair of 12x50 Nikon Fieldmaster binos that give me "double vision". Mighty nice binos, when I can rest them on something solid, otherwise with this high a magnification I tend to get a touch of green gilled seasickness from the pitch and roll!
They were hand-me-downs from a friend that goes thru optics like Charlie Sheen goes thru a singles bar. They have ridden under the front seat of my Jeep for years and when I pulled them out the other day, I notice the horrible double vision. Anyone with experience with optics wanna offer advice?
