Quick Answer
To calibrate thermal optics for hog hunting, start by setting the temperature range to 70-100°F (21-38°C), then adjust the gain to the lowest setting and focus on a dark object. Increase the gain until the object is visible, then decrease it until the image is clear but not overexposed. Repeat this process to ensure accurate temperature readings.
Setting Up the Thermal Optic
When calibrating thermal optics for hog hunting at night, it’s essential to begin in a dark environment with minimal background heat signatures. Set the temperature range to 70-100°F (21-38°C), which is typical for nighttime hog activity. This range allows the thermal optic to capture heat signatures from the hogs without picking up excessive background heat.
Gain Calibration
To adjust the gain on your thermal optic, start by setting it to the lowest setting and focusing on a dark object, such as a tree or a rock. Gradually increase the gain until the object becomes visible on the screen. This may take some trial and error, but the goal is to achieve a clear image without overexposure. As a general rule of thumb, start with the gain set to 10-20% and adjust from there.
Focusing the Thermal Optic
Proper focusing is crucial for accurate thermal imaging. To focus your thermal optic, adjust the diopter ring until the image is clear and sharp. Look for a clear, defined edge between the hog’s body and the surrounding environment. If the image is blurry or distorted, adjust the diopter ring until the edge is sharp and clear. This may take some practice, but it’s essential for effective hog hunting.
