A capable entry point into thermal optics with real field results against coyotes, but budget time to work through zeroing since the manual and higher zoom levels are where reviewers ran into trouble.

Overview
The AGM Rattler TS25-256 is a thermal riflescope with a 25mm lens, 256x192 core resolution, and a quick-release mount that also works as a handheld monocular. It suits hunters scanning for coyotes, hogs, or other night-active game rather than long-range precision shooting.
Several reviewers used it specifically for coyote work, reporting reliable target detection out to a few hundred yards and enough thermal contrast to pick out an animal in a field the naked eye missed. The recurring frustration is the digital zoom: more than one reviewer describes reticle shift or point of impact changes when moving past the base magnification, and several call the printed manual weak on zeroing instructions.
- 256x192 core resolution, 12um pixel pitch
- 0.39-inch OLED display, 8x digital zoom
- Video recording with 16GB built-in storage
- Waterproof, shockproof housing
Who it's for
Fits a hunter buying a first thermal optic for predator or hog control at moderate range, especially one who wants the quick-detach mount so the same unit can double as a handheld scanner. Less suited to shooters who need precise zero retention across the full digital zoom range.
What buyers say
From Amazon customer reviews.
Hunters report real results against coyotes and hogs at night, and like being able to pull the scope off its mount and use it as a standalone monocular. The main complaints are a manual that reviewers say doesn't clearly explain zeroing, and at least one report of point of impact shifting at higher digital zoom levels.
Strengths and trade-offs
Drawn from this product's published specifications.
- Quick-release mount doubles as handheld monocular
- Effective coyote and hog detection at night
- Clear image quality for an entry level unit
- Rechargeable battery is easy to swap
- Zeroing instructions in the manual are unclear
- Point of impact can shift at higher digital zoom
- Menu and setup feel complicated to some users
Performance notes
The scope pairs a 12um pixel pitch detector with Adaptive AGC, DDE, and 3D DNR processing to sharpen thermal contrast, displaying the image on a 0.39-inch OLED panel with up to 8x digital zoom. Reviewers who hunted coyotes and hogs at 40 to 150 yards found detection reliable, but at least one reported the reticle's zero shifting once magnification moved past the low end, so the digital zoom range is worth testing on paper before hunting with it.

Does the AGM Rattler TS25-256 hold zero across its zoom range?
