For the price, made in america, cant be beat. - Armasight Sidekick 640 1x19mm Thermal Monocular

Is it the best thermal, No. Don't expect an Apache gunsight FLIR, you will have to adjust the settings to get the best picture for the environment. However, what is this good for? This is perfect for scanning your environment for targets. If you scan with a scope thermal, you are bound to miss a bigfoot standing 20 yards from you walking by in a clown outfit. With this, you have something small, "cheap for thermals" and easy to use to scan the environment. Once you find a target, then you can switch to your main optic.
