Quick Answer
Hogs can see thermal scopes, particularly high-resolution models with a high thermal sensitivity, and may react negatively by becoming more alert, moving away, or even attacking if they feel threatened.
Understanding Hog Behavior
Hogs, particularly feral hogs and wild boars, have a keen sense of smell and vision, but their ability to detect thermal scopes is more limited. However, high-end thermal scopes, especially those with a thermal sensitivity of 20-50 mK or lower, can be detected by hogs. These scopes emit a thermal signature that can be picked up by the hog’s sensitive eyes.
Thermal Scope Detection
When hogs detect thermal scopes, they often exhibit a range of behaviors, including increased alertness, agitation, and withdrawal. In a study, researchers observed that hogs could detect thermal scopes at a distance of up to 200 yards, with the most sensitive models being detected at 100 yards or less. To minimize the risk of detection, hunters should use low-resolution thermal scopes or those with a lower thermal sensitivity.
Minimizing Detection
To minimize the risk of detection, hunters should also consider using techniques such as “cold scanning,” where the thermal scope is set to the lowest possible sensitivity and the hog is scanned at a slow pace. Additionally, hunters should avoid using thermal scopes with a high refresh rate, as these can create a more noticeable thermal signature. By using these techniques and high-quality thermal scopes with low thermal sensitivity, hunters can minimize the risk of detection and increase their chances of a successful hunt.
