Athlon Cronus ATS 2.6-10.4x35mm Thermal Monocular with Laser Rangefinder

This Cronus ATS monocular pairs thermal imaging with a laser rangefinder good to 1000 yards, which turns a scanning tool into a spotting tool. Pick up heat at the treeline, range it, and you have the location and the distance settled before the rifle ever comes up.

Magnification runs 2.6x to 10.4x through a 35mm lens. The bottom of that range is wide enough to sweep a field without swinging your head around, and the top is tight enough to work out what you are actually looking at. A handheld unit like this earns its place as the scanner in a night setup, doing the searching so the optic on the rifle only has to do the shooting.
