Works great - Guide USA TU 650 M 3.0 3.7x50mm 30mm Tube Thermal Rifle Scope

Ive used this scope for 4 month now. It is loaded with features. Things to keep in mind is the daytime mode and thermal has to be sighted in separately since it is two different sensors. In daytime mode you have to go in settings and switch to night mode so it will work properly with ir lights. Thermal was my main feature since I'm shooting hogs and coyotes at night. The recording is nice especially when its set on to record when you shoot so if you get excited like me you wont miss the opportunity to look back! Most people may understand most of this but it may help others when spending money getting into thermals. The range finder is almost essential for judging distance in a thermal which to me is tuff without land features on a property you know well! Ive used cheaper sensor but with the 640 I can easily distinguish hogs in 95 degree weather in Ga.
