A monocular is a modified refractive telescope that uses a series of lenses to magnify images of distant objects by passing through light and regularly prisms resulting in a lightweight, compact telescope.

In reality, the monocular is a smaller and lighter low-energy telescope. These monoculars are mainly used for birding, hiking, hunting, and more.

Like binoculars, the primary purpose here is to bring distant subjects closer so that you can see them better.

These vision devices have recently come a long way in affordability and quality. They are light and small enough to put in a pocket, but powerful enough to see the unique landmarks of the birds you see.

The debate as to whether this unit is preferable over conventional thermal imaging is an endless topic of discussion within the field.

If you need to buy a monocular on the market, you have to read a lot of things, because it is very difficult to purchase the best of the many products.

To overcome this, here are the two best inexpensive monoculars for you according to your needs: Armasight PVS-14 and Flir Breach PTQ136.

Also, if you want the best of these two, we are comparing between Armasight PVS-14 and Flir Breach PTQ136 Monocular. It’s done through only reviewing and comparing both properties and functions.

Night Vision monocular Vs Thermal imaging monocular:

Before going any further, it is important to describe the subtitles between night vision and thermal imaging technology.

Initially, let’s discuss on night vision technology.

Night Vision:

The night vision was developed by the Germans in the 1930s as a way to survey enemies. During World War II, the U.S. created its night vision. Being able to see at night can be a definite benefit, especially if you are hunting, observing wildlife, or engaged in search and rescue.

A Night Vision device is an optical machine that provides images to be performed in total darkness. Night vision is a technology that cannot be compensated for the operation of special forces at night or during the hunt. It is also useful for exploring bunkers, caves, and other dark places.

This type of device is used by military, police, hunters, border patrols, and even ASG soldiers, which serve as a multi-tasking, universal night vision device for each position.

If you want to end up with better visibility, then you get night vision systems. There are many devices today that are intended to help with night vision, and one of them is monoculars.

Night vision monoculars have many purposes today, each having a performance that forces many people to choose. They are often liked for being simple to use. With just one hand, you can be in a position to see clearly at night.

Thermal vision:

Thermal imaging is a technology that can detect infrared radiation of objects by improving the visibility of objects in dark environments and generating an image based on that information.

It is a type of technology that has developed a wide range of applications over the years. Specifically, this is a great form of night vision technology, capable of working in the absence of any light, and can even work in smog, fog, haze, and smoke.

Not only does this image help us recognize objects in complete darkness or dense smoke, but they can also use the sensor information to measure temperature differences.

The spectrum of visible light is only a small portion of the detectable signals or waves of a large group that travels through the material. The electromagnetic spectrum includes radiation from several invisible wave kinds and each with an individual wavelength. Thermal radiation is one of these, which has longer wavelengths than visible light, so it is usually invisible to the human eye.

Objects with an absolute zero temperature emit detectable levels of radiation. The high temperature of an object, the more radiation is emitted. Thermal cameras deliver the invisible thermal radiation “visible” in the shape of tropical images using the temperature differences between objects.

Armasight PVS-14 night vision Monocular:

The Armasight PVS-14 is the first genuine multi-use monocular that allows it to meet a variety of military needs. This is one of the most popular night vision devices for law enforcement professionals.

The Armasight PVS-14 SD night vision monocular is provided with a high-performance Gen 2+ tube that delivers 45-51 lb / mm resolution. The Armasight PVS-14 uses the same structure, and its combat-proof design is lightweight, and difficult in excellent optics.



  • Compact, rugged design
  • Manual brightness control
  • Ergonomic, easy to operate controls
  • Built-in with an infrared illuminator and flood lens
  • Bright light cut-off
  • CR 123A lithium battery or AA alkaline, adapter included

The PVS-14 monocular is compatible with many accessories, including head/helmet-mounted, hand-held, and camera or weapon mounted. It is one of the best available systems, designed for the most demanding nighttime Military or law enforcement operations.

The Armasight PVS-14 is a single-tube night vision system with a conventional 40 ° FOV or wide 51 ° FOV for ample peripheral vision in light conditions near zero. A broad FOV increases situational awareness while requiring less head-turning, thus reducing fatigue.

The Armasight PVS 14-night vision is designed to detect short-range and identification. This device is a fully waterproof, and it only requires a waterproof device and only needs a 1.5-volt AA battery, which can last you up to 50 hours.

If you want a powerful device with night vision optics and want an easy portable monocular that is worth its cost and great value, then the Armasight PVS 14 Night Vision monocular is the ideal choice for you.


  • Made to military specifications
  • Superior clarity and contrast
  • 100% water and weatherproof
  • Head or helmet-mountable for hands-free usage
  • Impressive battery life


  • Not suitable to use in daylight

Flir Breach PTQ136 thermal imaging monocular:

The FLIR Breach is an excellent tool for law enforcement, military, pest control, or firefighting, and it can detect heat signatures by IR light.

The FLIR Breach indicates the FLIR boson core of the 12um pitch thermal sensor, and it is designed with an inclinometer and digital compass. This FLIR Breach’s setting enables you to obtain a compass calibration or adjust the image point on the screen with other elements.



  • High-definition FLCOS display
  • Flir boson thermal core
  • Thermal imaging concept
  • Video recording capabilities
  • Exceptional vision
  • Super tactical value
  • Digital compass/inclinometer

The digital display of this device can also be used to record images and videos spontaneously, and the user can hold evidence of their visions at a later time. The FLIR breach is designed with an auto-gating feature that regulates the increase of the thermal image and prevents the overhead balance of thermography imaging.

The FLIR breach is intended with the eyecup to remove the mild bleeding from the visual and surrounding atmospheric conditions. The display features 16mm internal eye relief with a +5 to -5 diopter adjustment panel.

The breach also provides accurate digital compass measurements and gradient measurements for geo-location in addition to the main factors of thermal imaging.

The Breach PTQ 136 has an internal storage of 2.5 hours of video recording and can take up to 1,000 images. Also, it can save both photos and videos.
