Why does a semi-circular flare appear at the bottom of my thermal imaging screen after a shot?
Quick answer
If you're using a silencer or compensator, raise the riflescope height to eliminate the flare. Re-zero the riflescope afterward.
If you notice a flare on your screen after firing a shot, your gun likely has a compensator or silencer that radiates heat when fired. To resolve this issue, we recommend raising the height of the riflescope. Increasing the space between the riflescope and the silencer will make the flare invisible.
Keep in mind that after adjusting the height, you’ll need to re-zero the riflescope for accuracy.

What is zoom zeroing used for?Zoom zeroing enhances the precision of riflescope zeroing by allowing adjustments while the scope is zoomed in. For instance, at 2x magnification, the click value becomes twice as small (e.g., 1.6x2=3.2). Similarly, at 4x magnification, the click value reduces to one-fourth. This allows for finer adjustments to the point of impact, resulting in a more accurately zeroed riflescope. Click values for each scope are detailed in the reticle catalog or user manual.
