Base magnification is the optical power built into the scope, while digital zoom enlarges the image after it has been captured. The key difference is that optical magnification preserves image quality, whereas digital zoom can introduce pixelation and reduce detection range. Understanding this trade‑off helps you choose a thermal that works with the distances you expect in the field.
Open fields and flat farmland favor higher base magnifications because you often spot game at 300 yards or more. In contrast, dense woods, brushy swamps, or rolling hills limit line of sight, so a lower magnification with a wide field of view lets you locate movement faster. Digital zoom can be useful for a quick glance at a distant target, but rely on the scope’s native power for the first lock.
When hunting hogs and coyotes, most encounters happen within 150 to 250 yards. A 3x or 4x base magnification paired with a modest 2x digital zoom gives a good balance of detail and situational awareness. If you frequently stalk in open pasture, consider a 5x or 6x optic and use digital zoom sparingly to fine‑tune your aim.
Finally, remember that field of view shrinks as magnification rises, which can make it harder to track fast‑moving predators. Choose a scope that offers a comfortable field at your typical hunting distance, and test the digital zoom in the field before relying on it for a shot.
