Today's hunters and sport shooters have access to better and higher-performance equipment than ever before. From super accurate laser rangefinders to carbon-wrapped barrels, we can now purchase equipment that would have only been available to the military just decades ago. As technology like high-performance optics starts to commingle with today's lightning fast microprocessors, there are also whole new classes of gear that are revolutionizing the consumer marketplace. In this article, we'll go deep on one such technology—the best thermal scopes.
Thermal scopes were once a technology that was reserved strictly for the most elite military snipers. Though heat signatures have been valuable for target acquisition for decades, thermal scopes have been out of reach for the average consumer until the last decade. Today you don't have to be on advanced operations to enjoy the benefits of thermal optics. Hunters and shooters can now get their hands on excellent thermal optics for prices comparable to some premium-grade non-thermal scopes.
With new products and manufacturers hitting the market each year it can be hard to know which are the best thermal scopes for your money and which are cheap knock offs. So we dug deep into some of the best thermal scopes on offer today from the industry's top brands. While you'll almost definitely pay more for a thermal scope than a traditional optic, you may be surprised by how affordable thermal scopes can be.
So if you're ready to tune up a rifle for home defense, predator hunting, and just plain fun on the range, then read on. We'll get you up to speed on everything you need to know about the best thermal scopes available today.

The Verdict
Image Source: Unsplash.com
Every hunter, shooter, soldier, and tactical law enforcement agent will have different needs when it comes to optics. Choosing the best thermal scope for your needs, therefore, is truly a matter of context and preference. If you're a forward operator whose life depends on long-range thermal detection and 50X magnification, then a high-end scope will be worth every penny.
For casually hog hunters, on the other hand, a smaller internal screen, lower refresh rate, and shorter thermal detection may work out just fine and save a boatload of money. The only way to be positive you've chosen the best thermal scope for your needs to bit the bullet (not literally) and try a few.
With that said, our top pick as the best thermal scope from this group is the ATN THOR-HD 640. This scope offers a huge number of features for a price that is attainable for the average hunter who is willing to save a few pennies. With an impressive 640x480 internal screen and 50X digital zoom, this scope will out-compete most scopes in its price range. It will also have you dialed in on thermal signatures at greater distances than more expensive scopes. Whether you're a professional shooter or a weekend warrior this scope is definitely worth a look.
