Ergonomic design

The Firefield monocular has a very distinctive shape. It is quite ergonomic and doesn’t cause fatigue over extended use. It is easy to handle and operate. Plus, it features non-slip technology, which ensures a firm grip.

This magnification allows you to view the target clearly at a certain distance, improving your chances of success.

Field of View

Another prominent feature of this excellent monocular is a large field of view of 15°.

This feature makes hunting convenient by allowing you to view large parts of landscapes through the lens. You can easily scan a terrain anywhere from 600 to 3000 feet away from you.

The buttons are perfectly placed on the housing, so you won’t have any trouble locating them even in the darkness.

Built-in illuminator

What makes this Firefield monocular extremely special is the built-in 809nm illuminator that enhances the clarity and brightness of your target. The illuminator lights up the target while keeping you hidden.


The Nightfall monocular works on two replaceable AA batteries. The batteries last for more than 72 hours when not used with an Infrared illuminator and 20 hours with it.

So, you don’t have to worry about keeping a spare pair of batteries for an overnight trip.

Because of its high image quality, this device is suitable for bird watching and watching animals in your backyard.
