Zeroing a thermal scope is the first step to reliable night hunting. Whether you are stalking a hog in a dense bottomland or calling in on a coyote at a waterhole, a properly zeroed scope gives you confidence and saves ammunition.
Start by mounting the scope on a stable platform and making sure the base is perfectly level. Choose a realistic zero distance - 100 yards works well for most hog and coyote scenarios - and place a high‑contrast target at that range. Use the built‑in reticle or a laser boresight to align the point of aim with the point of impact, then adjust windage and elevation knobs in small increments until the shot lands on the bullseye.
After the initial adjustments, fire a three‑shot group at the same distance and re‑measure the impact. If the group is off center, repeat the fine‑tune process. It is a good habit to repeat this verification after a change in temperature or after moving the scope to a new rifle, as thermal lenses can shift slightly with heat.
Common mistakes that ruin a zero include forgetting to level the scope, zeroing at a distance that does not match your typical shot, and failing to tighten the mounting rings after adjustments. Many hunters also neglect the effect of parallax - if the scope has a parallax setting, set it to the same distance as your zero. Finally, avoid using low‑contrast targets; a bright orange or white board works best for thermal imaging.
Keep a quick checklist in your bag: level the mount, set the zero distance, use a high‑contrast target, adjust windage and elevation, verify with a shot group, tighten all screws, and re‑check after temperature changes. Follow these steps and you’ll keep your thermal scope on target night after night.
