Considerations when looking for the Best Thermal Scope for Deer Hunting

Here are the key factors you should consider when shopping for the best thermal scope for deer hunting.


Thermal scopes are great investments that come at a higher price tag. Generally, thermal scopes cost more than night vision scopes or standard scopes. Typically, how much you spend on a thermal scope for deer hunting will largely depend on your budget, needs and skills.

If you are a beginner, you should get an entry-level thermal scope that’s not only easy to operate but also less expensive. Most entry-level thermal scopes feature lower resolution, fewer high-tech features and shorter range.

On the other hand, if you are a seasoned hunter looking to take your deer hunting skills to a higher level, you should get a professional-grade model. Such scopes fall in between $2,500 and $5,000. They have high-end features, longer detection range and high resolution. You can also go for the high-end models that cost more than $5,000 if you can afford one.


Magnification helps bring distant deer closer. It also helps you to get close-up view of the target without having to get close to it. Your ideal magnification will largely depend on your hunting environment and personal preference.

If you intend to use a lower-resolution scope, make sure that you get a model whose magnification doesn’t exceed 8x. Too high magnification and your images will become grainy. Also look at whether the scope provides both optical magnification and digital zoom.

Built-In Rangefinder

Its indispensable to get a thermal scope with a built-in rangefinder for deer hunting. It will not only save you the hassle of having to carry a separate rangefinder, but it will also make your hunting simpler as you won’t have to keep switching between the scope and the rangefinder.

Sensor Resolution

The most important feature of a thermal rifle scope is its sensor resolution. When it comes to deer hunting, go for a scope with the highest sensor resolution possible. Higher resolution means more pixels to capture more infrared light. This results to production of high-quality images even in total darkness. The most common resolutions are 384×288 for the entry level thermal scopes and 640×480 for the more expensive models.

Refresh Rate

The other important factor you should consider is the refresh rate. If you are new in the market, refresh rate is the number of images the thermal camera takes per second. Low-end thermal scopes have a refresh rate of about 30Hz. This is not ideal for deer hunting as the image produced is often of low quality. The best refresh rate for deer hunting is 50Hz or 60Hz. At this rate, the thermal camera keeps up with the target or rifle’s movement easily and produces crisp clear images.

Battery Life

The thermal scope’s battery life can have a considerable impact on the success of your deer hunting expedition. Unfortunately, inadequate battery power forces some hunters to cut short their journeys. To avoid this problem, be sure the model you’re contemplating has a battery that can provide more than 8 hours of continuous operation. If you’ll be engaged in long hunting sessions and this won’t be enough, you should get an external battery pack which will offer more hours of use.


It’s also important that you look at how heavy the scope weighs. If your hunting involves moving from one location to the other in search of game, you’ll want a thermal scope that doesn’t add any unnecessary weight on you and the rifle. So, go for a scope that’s lightweight and portable. Typically, a model that weighs not more than 2lbs will be ideal.
