Thor 5 lrf 640 - ATN Thor 5 LRF 3-24x 640x480 12 Micron Smart HD Thermal Rifle Scope, 30mm Tube w/ Gen 5 Sensor

Comparing to the Thor model,which is two models back, night and day difference. The built-in range finder is a must, click of the button and you're ready to shoot. I also have the Thor 4 day/night scope, the weight and size difference with the rangefinder on both results in a smaller and lighter setup. I'm glad they got rid of the dial nob on the Thor 5 as it never worked very good in the cold. The zoom is a click of the button up or down, brightness is a click of the button cycling through 5 settings is very nice. Keeps you from blinding yourself at night. The auto refresh is nice as long as it doesn't do it when you're going to shoot. I haven't looked into the instructions to see what options I have with adjusting the refresh. Comparing to the Thor, awesome upgrade. Comparing size, weight, button function and built in rangefinder to a Thor 4 day/night scope, again awesome upgrade. They definitely improved usability. Definitely go for the Thor 5 LRF.
