Like Ben said, it boils down to use of item. If you get a chance, go to Bass pro or a gun show. Try both Gen1 and 3. It is night and day in comparison. When you get into shooting with these items is when price means a world of difference. Higher end= better clarity. Judd had the civilian version PVS7. Pricey, but, great clarity, waterproof, all the specs of military issue. Hope this helps.
