Small but exceeds advertised capability - Torrey Pines Logic T12-M Mini Thermal Imager

The capability of this unit is only limited to the size of the screen. I have been able to detect livestock in my open pastures at distances exceeding one hundred seventy five yards. You will also be able to detect the heat signature if an animal has been resting or stationary in a location for a period of time. Overall, it works great, I do wish the screen were a little larger, but if the display were any bigger, it would also give off quite a bit of visible light as well.
