Tactical Rifleman's Two-Step Method for Focusing Night Vision

In a short video, Tactical Rifleman breaks down the two-step process for properly focusing night vision devices, using a battery-less PVS-14 to demonstrate without the distraction of an actual image through the tube.

Key points

• Two adjustments exist on any night vision unit, whether it's binos, quads, or weapon mounted: the rear diopter and the front objective lens.
• Start with the objective lens unfocused and the diopter set to zero before making any adjustments.
• Focus the diopter first by looking at the internal artifact or noise inside the tube, like a speck of dust or the honeycomb pattern, not by looking through the device at a scene.
• Diopter setting is permanent once dialed in to your eyesight, even with prescription glasses, and shouldn't need to be touched again.
• Objective lens handles everything else afterward, whether refocusing close for reading or charging a door, or back out to distance for the courtyard.

Quick take

This is a practical, no-frills breakdown aimed at anyone who owns or is about to own a night vision device. Tactical Rifleman keeps it simple: diopter once, objective lens as needed. For owners who've fumbled with blurry NVDs in the field, this is a quick fix worth watching.
