Jumped in the thermal game and glad i did! - Armasight Zeus 336 3-12x50mm Thermal Imaging Weapon Sight, FLIR Tau 2

I wore myself out researching different brands, calling the manufacturers, agonizing over the choices. Finally I chose the Zeus 3.

The scope is excellent and you will need to spend some time with it as there are some nuances to master. Once you do however, the buttons are intuitive and the color schemes are incredible.

Different times of day and differing day/night temperature differentials will need to be compensated with changing the color scheme and contrast to get an optimal sight picture. This is not difficult to master. You just scroll through the schemes and judge the sight picture, then dial in the contrast. Only takes about an hour to learn once you know you need to do this, and once you do, seconds to complete.

I advise the battery pack. You will wish you ordered it if you do not. It makes the learning curve much smoother.

My only Complaint is that the wire connection into the extended battery pack seems to pull apart with use. It does not seem to me to be water resistant any longer as the white and black wire are showing where the insulation has pulled out of the battery compartment. The wire connection at the plug adapter to the scope seems better constructed and has stayed intact. That said, you will still want the external battery pack without a doubt.
