Hog hunter - Armasight Zeus 640 3-24x75mm Thermal Imaging Rifle Scope

This is the second Armasight/Flir thermal scope I have purchased the 1st one was a 42MM lighter smaller got the job done just fine, this time I purchased exact same spec scope with a 75MM lens I love is. Beware of OPMOD packaging I paid less for this scope and HDDVR than my OPMOD bundle for smaller scope. Optic planet will Bundle item and color them Tan and I did not realize that I paid a premium price for that Tan color 1st go around. The sales rep on the 1st told me it was a better deal till i challenged her on it.
I see alot of pro and cons people complaining you cannot see thru glass, hey if you truly hunting leave the truck, blind or cushy enclosure. one true complaint is scope get grainy in drizzle but you can still see heat signatures. I will talk thermal over night vision IR lit scope any day of the week.
