The main differences are the design and the sellers. Bushnell has a great U.S. presence and customer service, and has their night vision scopes made a bit more ergonomically.
The performance will be almost identical between the two units. All first generation night vision units have main components made in Ukraine, and are imported to America.
The Bushnell should be a better product due to requirements and pull of a huge company. It also looks nicer and feels better in your hand.
As long as you understand that you'll be getting a unit at the absolute entry level and don't expect too much in the way of brightness and picture quality, you won't be disappointed. _________________ Aim Hard!
