I'm new to night optics; where should I start in the Know-How Hub?

We recommend starting with our NVU Universal Thermal & Night Vision Guide section, which covers the basics, such as the differences between thermal and night vision scopes and tips for choosing the right style for your needs.

How do I properly zero my thermal scope?

Zero at base magnification using a high-contrast or heated target. Fire a 3-shot group, enter the zeroing menu, and move the reticle to the center of that group rather than the target center. Specific step-by-step video tutorials are available for Nocpix, InfiRay Outdoor, AGM, RIX, and DNT Optics devices within the hub.

What is the difference between a dedicated thermal scope and a clip-on system?

A dedicated thermal scope is a standalone unit with its own reticle. A clip-on system sits in front of your existing day scope, allowing you to use your day scope's reticle for aiming.

How do the ballistic calculators work on LRF models?

The ballistic calculator uses data from the Laser Rangefinder (LRF) along with your specific rifle and ammo profiles (velocity, BC, and sight height) to calculate bullet drop. This allows the device to shift the reticle or provide a holdover dot for more precise shooting at various distances.

My image looks a bit blurry or has lines in it; how can I fix this?

First, try running a manual NUC (Non-Uniformity Correction) to clean up image artifacts. You should also check your diopter to ensure the menu text is sharp and then adjust the objective focus ring for the scene. If the issue persists, ensure the sensor has had 3–5 minutes to warm up.

Great scope for the money! I have two other Rix optics and this is performed just as good as them!

Great scope for the money! I have two other Rix optics and this is performed just as good as them! Obviously the DBH D6 and L6R are higher resolution but for a 384 unit this scope looks great! I purchased two to put on mine and my son’s AR rifles and it fits the bill perfect for the coyote hunting we do in Idaho.
