This video demonstrates that thermal clip-on optics require collimation, not traditional 'zeroing'. The process involves adjusting the internal digital screen's X and Y values to align the thermal image with the day optic's aiming point. Proper collimation ensures the point of impact matches the point of aim, a crucial step for accurate shooting with these devices.

Quick Summary

Thermal clip-on optics require collimation, not traditional zeroing. This process adjusts the internal digital screen's X and Y values to align the thermal image with the day optic's reticle, ensuring the point of impact matches the point of aim.

Frequently Asked Questions

What is the difference between zeroing and collimating a thermal optic?

Zeroing typically refers to adjusting the physical reticle of a scope to match the point of impact. Collimating a thermal clip-on involves adjusting the internal digital screen's image (X/Y coordinates) to align with the day optic's reticle, ensuring the point of impact matches the point of aim.

How do you collimate a multi-functional thermal optic?

Collimation involves accessing the optic's internal settings, usually via an adjustment menu, and modifying the X and Y values. These values shift the digital reticle on the screen until it perfectly overlays the aiming point of your primary day optic.

Are the collimation settings for thermal optics universal?

No, collimation settings are not universal. The specific X and Y values depend heavily on the individual optic, the riser height used, and the specific rifle and day scope combination.

Why is collimation important for thermal clip-on optics?

Collimation is crucial because it ensures that where you aim through your day optic corresponds precisely to where the thermal image's reticle is projected. Without it, your point of impact will not match your point of aim, rendering the optic inaccurate.
