Best Thermal Scopes for Coyote Hunting: A Montana Guide’s Field-Tested Recommendations

The first time I watched a pack of coyotes move through our ranch’s winter wheat field at 2 AM, invisible to the naked eye but clear as day through thermal imaging, I knew the game had changed forever.

Two springs ago, we lost seventeen calves to a particularly aggressive coyote pack that had learned to avoid traditional hunting pressure. These weren’t your average opportunistic predators—they moved like ghosts, hit fast during the darkest hours, and vanished before dawn. After weeks of frustration with conventional night hunting tactics, I invested in my first thermal scope and haven’t looked back since.

Over the past two years, I’ve tested seven different thermal scopes across Montana’s varied terrain and extreme weather conditions. From the sub-zero predawn hours in the Bitterroot Mountains to sweltering summer nights when thermal crossover makes imaging challenging, these optics have proven their worth where it matters most—protecting livestock and maintaining ecological balance.

Sarah, my wife and our local wildlife biologist, initially questioned whether thermal technology might give hunters an unfair advantage. After watching me eliminate problem predators with surgical precision while avoiding non-target species, she’s become a convert to the responsible application of thermal hunting technology.

Bottom Line Up Front: The Trijicon REAP-IR 35mm has become my go-to thermal scope for serious predator work, delivering unmatched clarity and reliability when livestock protection demands zero compromise.

Understanding Thermal Hunting: Beyond the Technology

The Reality of Predator Behavior: Coyotes are primarily crepuscular and nocturnal hunters, making traditional optics inadequate for effective management. My grandfather used jacklight hunting with varying success, but thermal imaging reveals the full scope of predator activity that occurs beyond human visual limits.

Ethical Considerations: Advanced thermal technology comes with enhanced responsibility. These optics enable positive species identification at distances where conventional hunting methods fail. This capability should improve ethical harvest rates, not simply increase kill opportunities.

Conservation Impact: Effective predator management supports overall ecosystem health. By removing problem individuals while preserving stable pack dynamics, thermal hunting can be a valuable wildlife management tool when applied responsibly.
