Check out the officiall ATN website. I like these BinoX 4T www.atneu.com/thermal-binoculars for instance as these modern hunting binoculars come with a highly potent laser rangefinder thats effective for up to 1,000 meters. The infrared binoculars are also fitted with an in-built IR illuminator as well as the latest thermal sensor operating at 60Hz. They also avail a variety of color modes as well as a Smooth Zoom feature. Indeed, the BinoX 4T thermal binoculars provides a full-spectrum functionality in the field, something much-needed by every lover of outdoor activity. I have been using it for a year or so and should say it is cool and quite effective
