You get what you pay for - InfiRay Outdoor Rico Micro V2 1-4x25mm Multi-Purpose Thermal Monocular

I have an Armasight 640 sidekick, as well as this one. The only reason I did not buy this originally was because it was 6K, while the Arma was only 3K... Needless to say, now the arma is 2500 and this one bumped down to 4K so I just had to bite the bullet and finally get it. The truth is you get what you pay for. This thermal is neck and shoulders above most others. I still use my Arma for navigation as it has great field of view and what not, but this rh25 is SO much better, smoother, and more versatile
