MOD-3 Night Vision Monocular System Info

Posted by Adam Barker on

MOD-3 Modular Night Vision System

The MOD-3 is a revolutionary new night vision system. Until now you could either have a binocular, or monocular. Using a bridge adapter to utilize two monoculars as a binocular has been done for years, but it has significant drawbacks. The weight of such a unit is over 800 grams, and they typically cannot be collimated. Many people enjoy using two monoculars when hunting. One on a neck lanyard for spotting, and one on their rifle. Yet most wish to avoid the cost of purchasing a binocular and two monoculars.

MOD-3 Optical Pod

The MOD-3 overcomes these problems by utilizing Optical Pods that are waterproof, Nitrogen purged units that can be installed into either a monocular or binocular. Power is conducted to the intensifier tube and indicator LEDs by means of spring loaded, gold plated contacts. Even the springs are gold plated to prevent corrosion.


The Optical Pods can be assembled in the MOD-3 Binocular Bridge to form a full function binocular. A latching mechanism firmly holds the Optical Pods in place and is easily manipulated with one finger. Installing or removing the Optical Pods is accomplished in just a couple seconds.

MOD-3 Bridge with Optical PodsMOD-3 Bridge

The Binocular Bridge has the features you expect to find on a night vision Binocular. It has IP adjustment, dovetail mount, IR LED, IR LED “on” indicator lights in the viewing plane, and low battery warning. It also includes a circuit that powers the tubes long after most systems would have shut down, using the 3V lithium battery down to a mere 0.9V before shutting down. This allows you a large emergency reserve after your low battery indicator flashes.

The same style gold plated contacts that conduct power to the Optical Pods are also utilized in the Bridge assembly. These conduct power from the Optical Pods to a circuit board and eliminates the need for wires in the joint which moves as you change IP adjustment. This prevents any problems with wires breaking and failing in this area.


The IP adjustment is accomplished through IP screws such as the AVS goggles employ. The screws have ball detent ‘bumps’ as they are rotated, preventing vibrations from accidentally changing your settings. The MOD-3 Binocular can be collimated and weighs in at 618 grams.

The other half of the MOD-3 system is the MOD-3 Monocular Adapter. This adapts an Optical Pod into a full function monocular. It has the same circuitry as the Binocular Bridge which means you have a flood IR LED, IR “on” indicator, low battery indicator, and battery extender circuit. It uses the 3V lithium battery as well. It also accepts the IR Spot/Flood adapters like the PVS-7 goggles use.

MOD-3 Monocular (Optical Pod with Mono Adapter)

Like the Binocular Bridge, the Monocular Adapter releases the Optical pod with the press of one finger, allowing instant changeover from monocular to binocular. The monocular housing is waterproof and has a side mount like a PVS-14, allowing you to use it as you would any other monocular with head and weapon mounts. The monocular is 75 grams lighter than a PVS-14.
