Thermal Scope Sighting Tips
Before you can effectively use your new thermal scope, you have to properly sight it in. This can be done in just a few steps.
1. Start at 50 Yards
Use a heat-emitting target like a hand warmer and steel plate that’s been warmed by the sun.
2. Adjust for Wind and Elevation
Most thermal scopes have a built-in zeroing function, which helps users fine-tune for accuracy.
3. Confirm at Longer Ranges
Go ahead and test your rifle scope at 100 yards or more so you can confirm your precision before you head on out to the field.
Thermal Imaging is a Game Changer
It’s no longer a secret that thermal scopes outperform traditional optics in low-light environments.
Are you serious about improving visibility in even the most dark and challenging environments? A thermal scope is a must-have piece of equipment.
