The Leupold LTO-Quest HD is an advanced thermal imaging viewer and camera with a built in 300 lumen dual intensity flashlight. The rugged, rubberized body is small enough to fit in your pocket, and light enough that it won't slow you down in the field. Featuring a 320x240 thermal sensor with a 32° field-of-view, the LTO-Quest HD can detect a heat signature out to 750 yards using any one if its 8 color palettes. The micro USB port is used to both charge the LTO-Quest HD and download any images that are stored on the included, removable micro SD card.
