Nice thermal - Armasight Zeus 640 3-24x75mm Thermal Imaging Rifle Scope

I own a couple other Thermal Scopes and this one is my favorite.
Pros- able to detect animals, deer, hogs, etc. that you can't with your naked eye during the day or night. In pastures I can detect living things at over 900 yards and identify between a deer vs hog around 500-600 yards easily.
This unit starts up very fast and you can't hear it when it is on.
Being 60htz you can drive as fast as you want and scan fields without slowing down. Big plus checking cattle during winter.
Cons- buttons on top will tick you off if you have large fingers.
It takes quite a while to get use to the buttons and all they can do. I look it everywhere with me and used it daily to figure it out.
It eats CR 123's like candy! Invest in a truckload of them or by the extra battery pack like I did! I also have 123 recharables too.

Overall - the pros outweigh the cons dramatically and this is a must buy at under 7K, BUT worth the money so far if it is tough enough! You will not be happy if you don't get a 640 × 60htz I promise! I have 2 others I paid around the same and the are junk compared to this one!
