Armasight zeus pro 640thermal imaging weapon sight flir tau 2, 640x512 - Armasight Zeus Pro 640 4-32x100mm Thermal Imaging Weapon Sight

Am a professional coyote hunter residing in Northern Maine. I wanted to upgrade my night vision equipment so after doing several months of due diligence, I chose this top quality thermal unit which was rated to be durable enough to take harsh winter environments, while being transported on a snow machine. Not all thermal units are mil spec rated. The unit is very easy to use. Armasight has produced a very clear and understandable owners manual. I also found the Armasight instruction videos on You Tube to be very helpful as well. Sighting the unit was very easy. Using the unit on a bolt action rifle I used a (0) MOA extended Picatinny rail and reversed it in order to get the unit further back on the receiver and the eyecup closer to my eye when my head is on the stock. The set up is perfect. This thermal is top of the line and will be a terrific addition to my coyote hunting equipment. Coyotes can't hide in tree-line brush without being detected. Right now I'm comfortable making shots out to 250 yards adjusting off a 100 yard zero. Once I have some time in the summer, I'll start dialing in the MOA reticle and verifying my rifle for longer distances. Am very satisfied with this unit.
