Comprehensive Buyer’s Guide for Hunters, Ranchers & Night Operators
AGM Global Vision has quickly become one of the most popular thermal brands among American hunters, livestock owners, security professionals, and prepared civilians. But with so many devices—monocular, thermal scopes, clip-ons, 256/384/640 sensors, different lens sizes, refresh rates, and detection ranges—most buyers are left asking:
“Which thermal device is best for me?”
“What’s the difference between a monocular and a scope?”
“Do I really need 640 resolution?”
“Can a clip-on be as good as a dedicated thermal scope?”
This long-form guide breaks down every type of AGM thermal device, explains what each tool is designed for, and helps you choose the exact optic that fits your mission and environment.
AGM has earned a massive following because they deliver:
Military-inspired performance without the military price
Reliable sensors with clear image quality

Whether you’re scanning for predators, running night hog hunts, or wanting a modern home-defense/night-surveillance capability, AGM has a category designed specifically for your needs.
A monocular is a handheld detection device, perfect for scanning fields or woods for heat signatures. It is NOT intended to shoot with; instead, it gives you awareness before you take the shot with your rifle-mounted optic.

Tracking wounded game
Property surveillance & security patrols
