Before getting into the hot topic of clip-on thermal scopes, let me tell you what is the clip-on thermal scope and the difference between the ordinary thermal scope and clip-on thermal scope.

What is Thermal Scope?

The thermal scope is one of the hunting accessories that is mounted at the top of your rifle. It is commonly used for night hunting to gain an enhanced vision in the darkness.

The thermal scope is based on the principle of infrared technology (Wikipedia). The infrared sensor captures the heat emitted by the objects in the surrounding. This heat energy is then converted into an image and is reflected back to the eyepiece. So you’ll get a clear vision of your target even at a longer distance.

Why are Thermal Scopes Different from Other Scopes? 

Thermal scopes are versatile scopes that can be used during both day and night, unlike night vision scopes or day scopes. A traditional day scope can be used only during day time and it can’t help you during the night. Because day scopes are purely made of lenses and magnifiers that can easily take down the targets.

On the other hand, thermal scopes are based on sensors and light detectors that give you a perfect shot at any light conditions. That’s why thermal scopes are very essential for hunting.

What are Clip-on Thermal Scopes?

Benefits of using Thermal Clip-on scope

Before investing in any thermal scopes, first, you have to check out the benefits you get when using that scope. The clip on thermal scope is a trump card for your rifle and has many advantages. Let’s get into;

Easy to mount

The clip-on is designed with a clip attachment that is quite easy and quick to load or remove from the rifle. It just takes a few seconds to attach the clip-on.


Generally, outdoor enthusiasts stay in the wild for multiple days. We can’t predict the day of returning. So hunters dump a lot of things into their bags. So they always prefer lightweight gears which will not be a burden for them to carry. Clip-on thermal scopes are extremely lightweight and clip easily to any of your favorite rifles. It will not add much weight to your rifle. 

No change of Zero 

In clip-on thermal scopes, you need not want to re-zero the day scope once mounted onto your rifle while hunting. Because it can keep the zero of your day scope itself. Nowadays most of the clip-on thermal scopes are designed in this way. 

Dual-purpose handling

Clip-on thermal scope acts as a monocular while hunting. Using this scope, you don’t have to worry about manipulating your rifle and monocular at the same time to see or track your target. Instead of manipulating this tool you can relax and focus on your goal. Hence, this dual feature makes thermal imaging technology (Wiki)versatile.


Clip-on thermal scopes provide extra protection for the hunter in the field. The wilderness contains fearsome elements like fog, darkness, unknown terrain, etc.  Thermal scopes protect you from these critical elements by providing consistent and quality night vision while hunting.

Important Factors To Consider While Buying

Before investing in the clip-on thermal scope, there are few important points to keep in mind while picking the best clip on thermal scope for your rifle. 


Before getting a thermal scope add on, make sure whether the clip-on optic is suitable for your day scope. Size doesn’t matter, clip-on thermal scopes are compatible with a wide range of day scope lens sizes.

The one important thing you have to consider is the magnification. Manufacturers of clip-on scopes recommend using clip-on with minimum and maximum zoom of the day scope.


The next prominent thing you have to look for is the thermal capability which means the resolution factor, zooming range, target detection, etc. 

  • Resolution

The minimum resolution of 384×288 for a clip-on thermal scope enables you to detect animals around 500 yards. The image quality here is pretty good.

If you’re looking for high-quality images then 640×480 resolution thermal clip-on scope is the right choice. It allows you to focus the target as far as 1000 yards and the image quality is also extraordinary. 

  • Objective Lens: 

Clip-on thermal scopes vary in their lens sizes. It is available in three forms as 50mm, 75mm, and 100mm. But before purchasing, decide your range of shooting first.

A 50mm lens is great for short-range and mid-range hunting. While, the 75mm and 100 mm lens is a perfect choice for long-range shooters.

  • Digital Zoom: 

Most clip-on thermal scope offers up to 4x zoom, while expensive models can be up to 12x. This can be of two types; digital zoom only or a combination of optical and digital zoom.

The latter is good at giving quality images without blurring if you zoom-in.

  • Refresh Rate:

Refresh rates are also available in three forms; 30Hz, 50Hz, 60Hz. The modern thermal scopes come with 60Hz refresh rates which helps you track the moving animal easily and quickly. But the lower 30 Hz refresh rate may lag when focusing on a moving animal. 

So, if you want to track the fastest moving animal, then consider the clamp on thermal scopes having high refresh rates. 


A compact clip-on thermal scope is stable and will not make your rifle heavy. The lightweight design makes portability easier. So you’ll not feel overload when using lightweight clip-on thermal scopes. 


The bright and crisp display is very important for easy detection and tracking of animals. I recommend a clip-on with at least 640×480 display resolution for a clear view of the target. For a better view, you can go with an HD display having a high resolution of 800 × 600, 1024×768, or even more.

Along with the display, also check whether you can change the color palettes of the images and adjust the brightness of the display. 

Battery Life

Usually, most of the clip-on thermal scopes offer two CR123 types of batteries. It provides continuous operation for about 4-5 hours. If you need extra battery life, then you can get a battery pack separately. 

Video Output

Unlike other thermal scopes, most of the clip-on thermal scopes are not featured with video recording and streaming. So they possess an alternative method to record video with a digital video recorder. 

If you want to capture footage of your hunting adventure, then check out whether your clip-on thermal scope has a video recording option. 


I always recommend waterproof clip-on thermal scopes. As a hunter, you have to face many challenges in the wild such as the rain, snow, wind, etc. So make sure your scope is waterproof, fog-proof, and scratch-resistant. You need not want to bother about any climatic changes, you can move ahead with your clip-on thermal scope. 

The final thing you have to consider is the use of day scope and thermal scope simultaneously. This is explained in the benefits section above. 

Final Words

Clip-on thermal scopes are the best choice when compared to clip-on night vision scopes. Most of the hunters prefer clip on thermal scopes as it has a dual purpose; a monocular and standalone thermal scope. 

Find your next target on the hunt with Clip-On Thermal Scopes. Whether you’re hunting hogs or deer, doesn’t matter, but it is always good to have a best clip on thermal scope that is quick to set and ready to go whenever you need it most. 

Hope so my review will be helpful for you to invest in the Best Clip-on Thermal Scope. Enjoy your day and night hunting game with clip-on thermal scopes.
