Can You See Bullets With Thermal?

This video from Civilian Tactical explores whether bullets are visible with thermal imaging. Using a Nocpix Lumi L35R thermal monocular and a Girsan Witness X 9mm handgun, the experiment tests heat signatures on impact. The findings indicate that while bullets do raise material temperature, the effect is often too subtle or shielded to be clearly visualized by standard thermal optics, especially in dense media like ballistics gel.

Quick Summary

Thermal imaging can detect the heat signatures of bullet impacts, raising material temperature by 5-20 degrees Fahrenheit. However, dense materials like ballistics gelatin can shield these signatures, making bullet paths difficult to visualize. While direct impacts on targets show clear heat spots, the thermal effect through thick media is often too subtle for standard thermal optics.

Frequently Asked Questions

Can thermal imaging see bullets in flight?

While bullets generate heat, standard thermal monoculars like the Nocpix Lumi L35R are generally not sensitive enough to detect bullets in flight due to their speed and brief thermal signature. The focus is typically on the impact point or residual heat.

What happens to the heat from a bullet impact?

A bullet impact raises the temperature of the impacted material by approximately 5-20 degrees Fahrenheit. This heat signature is visible on thermal imaging, especially on surfaces that absorb heat well, like the DA target used in the test.

Why is it hard to see bullet paths in ballistics gel with thermal?

Dense materials like ballistics gelatin can shield the heat signature of a bullet's path. While the surface might show heat from skimming shots, the internal path's thermal signature is often too diffused or absorbed by the gel to be clearly visualized by thermal optics.

What equipment was used to test bullet visibility with thermal?

The test utilized a Nocpix Lumi L35R thermal monocular to view heat signatures and a Girsan Witness X 2011-style handgun chambered in 9mm for shooting. Ballistics gelatin and DA silhouette targets were used as impact media.
