Best Thermal Monocular - Buyer’s Guide

Based on our experience in finding the best thermal monocular, there are some factors that can make a big difference in your overall experience. Let's take a look at what you should look for before you buy.

Lens Material and Size

When choosing an infrared scanner, it is important to consider the lens material and size. Unlike binoculars or spotting scopes that use glass for their objective lens, many infrared scanners use germanium. This is because infrared light does not pass through glass. Germanium is invisible to infrared light, enabling it to pass through and relay infrared information to the electronics. The larger the objective lens, the more infrared light the sensor can capture. If you know you will be hunting in low-light conditions or at night, a larger lens will help you see more infrared energy.

Sensor and Resolution

The sensor, also called a microbolometer, is the key component of any thermal monocular. It is responsible for reacting to infrared waves or heat emitted by your prey (or human) and consists of pixels that send electrical impulses to the electronics for processing. The more pixels the sensor has, the better the image quality. Consider thermal monoculars - 384x288, then you get 110,592 pixels.

With more pixels you will see more detailed images and therefore be able to detect and identify animals with much more confidence. So when choosing a thermal monocular, be sure to pay attention to the sensor and resolution.

EXAMPLE: Pulsar Helion 2 XQ38 has 384x288 pix and the Pulsar Helion 2 XP50 has 640x480 pix. This means that you get a more detailed image in the second case.

Resolution

An important factor to consider when choosing a monocular. High end devices typically use an HD resolution such as 1280x960, while lower end devices may have a lower resolution such as 720x540 or even lower. More pixels usually means more detail, so you'll be able to see more of the animals or scenes you're exploring.

Type of Display

Type of display is also important to consider. LCD displays are common in low-end devices, but they don't work in temperatures below 15° F. If you're hunting or using a monocular in cooler temperatures, you need an AMOLED or OLED display. Keep these factors in mind when choosing a monocular to make sure you get the device that best meets your needs.

Base Magnification

This feature allows you to see objects closer to your eye than would naturally be the case, making it easier to hunt animals at greater distances. Most thermal monoculars have a magnification of 2.5x to 4x, but some have no magnification at all. Your choice of base magnification depends on how you intend to use the instrument. If you plan to hunt animals at long range, you will need a higher magnification. However, if you only need to detect objects at close range, a lower magnification will suffice. Ultimately, it is a matter of personal preference when deciding which base magnification to use.

Detection Range

Detection range is one of the most important specs to look at when shopping for a thermal monocular. This is because it directly impacts how effective the monocular will be at locating games. Detection range is measured in meters and is determined by two factors: the microbolometer size and the zoom level. Monoculars with large microbolometers and higher zoom numbers give you more extensive detection ranges. When shopping, keep in mind that the Detection Range is not the same as the Identification Range. Detection simply lets you know that an animal is present, while identification allows you to make out specific details such as size, shape, and color.

The quality of the monocular's optics plays the biggest role in determining how easy it is to identify animals at a given range. image quality is impacted by a number of factors including lens size, focus time, and display resolution. Higher-end monoculars will offer better optics and longer detection ranges, but they come at a higher price tag. Ultimately, it's important to find a balance between detection range and price that fits your needs.

Battery Life

If you plan to hunt for a long time, you need a device with a long battery life. Many thermal imaging monocular have a runtime of 6, 8 or 10 hours. If you know you only need an hour, you can get by with a cable-powered unit. Even better is to find a device that allows you to change batteries and extend your day in the field.

Waterproofing and Durability

Durability and water resistance are important factors to consider when choosing outdoor gear. Spending time outdoors can be hard on equipment, so it's important to find products that will last. Checking a product's IP rating is a good way to evaluate its durability. The IP rating system evaluates a product's enclosure for its ability to keep out dust, water, and other objects.

For example, an IP67 rating means the product is dustproof (index 6 or higher) and can be submerged in water for 30 minutes (index 7). When choosing outdoor gear, look for products with a high IP rating to ensure durability and longevity of use.

FAQ about Best Thermal Monocular

Here are some common questions that many people ask when they are considering buying the best thermal monocular.

What is the difference between a thermal imaging monocular and a night vision monocular?

Thermal imaging monocular and night vision devices are used for surveillance in low light conditions. However, there are some key differences between the two technologies.

Thermal imaging monocular, also called infrared camera, detects radiation in the infrared range of the electromagnetic spectrum and produce images of this radiation. A thermal imaging camera reproduces an image from heat - living and nonliving, but heated objects at any time of day, leave a thermal trace. Thermal imaging cameras are passive sensors that do not emit their own energy, so they can see objects in total darkness or through thick smoke or fog.

Night vision devices, on the other hand, use light amplification technology to allow operators to see in low light conditions. These devices do not work in fog or in very dark environments, as they require a certain level of ambient light to function.

Both thermal imaging and night vision devices have a wide range of applications, including military, law enforcement, search and rescue and hunting applications.

What's the difference between thermal and infrared?

Thermal imaging cameras measure the infrared radiation emitted by all objects and display that information as an image. The images produced by a thermal imager are known as thermograms. Infrared energy is part of the electromagnetic spectrum and its wavelength is longer than that of visible light. All objects above absolute zero (-273°C) emit infrared energy. The amount of infrared energy emitted by an object increases as its temperature increases.

The difference between thermal and infrared is that thermal imaging cameras can sense this emission over a wide area, while an IR thermometer can only sense the emission from a very small spot. Because of this, thermal imagers are sometimes referred to as “whole-scene” or “wide-field” images. What’s more, you can use a thermal imager to “see” in total darkness, through light fog, smoke, and most types of persistent background clutter that would obscure vision in the visible spectrum.

Can thermal imaging see through walls?

No, not the way we're used to seeing in different action movies. Walls are often thick enough and insulated enough to block any infrared radiation from the other side. If you point a thermal imaging camera at a wall, it will pick up the heat from the wall and not from what's behind it. However, there are some cases where you can use thermal imaging to see through walls.

If there is a large fire on the other side of the wall, for example, the heat from the fire might be intense enough for the thermal imaging camera to detect it. Also, if the wall is very thin or has a hole in it, infrared radiation can pass through it and be detected by the thermal imaging camera.
