RIX RNV 31S FAQs

What does the RNV-31S do? 

The RNV-31S is a night vision binocular that lets you see in the dark. It works by gathering light from the moon and stars to create a clear image for you to see.

What is "manual gain" and why do I need it? 

Manual gain lets you control the brightness of the image. Using a simple knob, you can make the view brighter or dimmer to adapt to different light conditions. This helps you spot targets more easily, whether it's very dark or there's a lot of moonlight.

When should I use the IR illuminator? 

You should use the IR illuminator when you are in complete darkness, like inside a building with no lights. It creates a beam of light that is invisible to the human eye but can be seen by the RNV-31S, allowing you to see when there is no other light available.

What kind of battery does the RNV-31S use? 

The RNV-31S is flexible and can use different batteries. It works with either a single AA or a single CR123A battery and comes with caps for both. A CR123A battery will last for at least 25 hours, while an AA battery will last for at least 20 hours. You can also use an external battery pack for up to 80 hours of use.

How does the "flip-to-power-off" feature work? 

When the RNV-31S is mounted on a helmet, you can flip it up and away from your eyes. When you do this, the device automatically turns off to save battery and keep you hidden. When you flip it back down into position, it automatically turns back on.

How does Bright Source Protection help me? 

This is a safety feature that protects the night vision from damage. If the device is exposed to a very bright light for more than one minute, it will automatically shut itself off to protect the sensitive internal parts. You must restart the device to use it again.

What makes the RNV-31S different from the older RNV-31? 

The RNV-31S is an upgraded model with several improvements. It uses higher quality "Mil-Spec" optics for a clearer image , has a stronger housing made of more durable materials , and gives you more battery options by supporting both AA and CR123A batteries. 

Where can I purchase the RNV-31S?

When you buy from a trusted dealer like us, you can be confident you're getting a brand-new, genuine unit, not a grey-market or refurbished product. Purchasing from Atomic Defense ensures expert customer support and a full 3-year manufacturer's warranty. For your safety, it's crucial to buy from a reliable source.
