With the Thor 4, I found myself zeroed and ready to go in a fraction of the time it used to take with traditional scopes.
The built-in ballistic calculator is another feature that has proven invaluable in the field. This sophisticated tool takes into account a wide range of variables, including distance, angle, atmospheric conditions, and even your specific ammunition’s ballistic profile. The result is a level of accuracy that was previously unattainable without extensive manual calculations. During a long-range varmint hunt in Texas, this feature allowed me to make precise shots at distances that would have been challenging, if not impossible, with a standard scope.
The smart rangefinder is yet another tool that enhances the Thor 4’s utility. By eliminating the need for a separate rangefinding device, ATN has streamlined the hunting process. The accuracy of this feature is impressive, and I’ve found it to be reliable even in challenging lighting conditions. Whether ranging a distant hillside for potential targets or quickly assessing the distance to a moving animal, this integrated rangefinder has become an indispensable part of my hunting toolkit.
Video Capabilities That Capture the Action
In today’s digital age, the ability to record and share our hunting experiences has become increasingly important. The ATN Thor 4 640 1.5-15x doesn’t disappoint in this regard, offering video recording capabilities that are truly impressive for a thermal scope. With the ability to record in 1280×960 resolution at 60 frames per second, the footage captured through this scope is smooth, detailed, and perfect for reliving your hunts or sharing them with fellow enthusiasts.
The Recoil Activated Video (RAV) feature is particularly innovative. By automatically recording a few seconds before and after your shot, it ensures that you never miss capturing those crucial moments. I’ve used this feature to analyze my shooting technique, document successful hunts, and even capture unexpected wildlife encounters. The quality of the footage is such that it’s not just useful for personal review but is also suitable for sharing on social media or even using in hunting shows or documentaries.
Moreover, the Thor 4 offers WiFi streaming capabilities, allowing you to share your hunt in real-time with companions or viewers back home. This feature opens up new possibilities for collaborative hunting or even remote guided hunts. The 64GB SD card capacity ensures that you have plenty of storage for extended hunting trips without worrying about running out of space.
Real-World Performance and Versatility
In the field, the Thor 4 640 1.5-15x consistently performs at a level that justifies its premium price point. The 60Hz refresh rate is a standout feature, providing smooth, real-time imaging that makes tracking moving targets a breeze. Whether you’re following a running boar through dense brush or trying to lead a fast-moving coyote, the fluid motion rendering of the Thor 4 gives you a significant advantage.
The magnification range of 1.5-15x offers versatility for a wide range of hunting scenarios. At the lower end, you have a wide field of view perfect for scanning large areas or tracking close-range targets. At maximum magnification, you can zoom in on distant heat signatures for positive identification and precise shot placement. This flexibility means the Thor 4 is equally at home in dense forests, open prairies, or anywhere in between.
One of my most memorable experiences with the Thor 4 came during a late-season deer recovery in northern Minnesota. After a fellow hunter made a less-than-ideal shot as darkness was falling, we were faced with the daunting task of tracking a wounded deer in near-total darkness. The thermal imaging capabilities of the Thor 4 made what could have been an hours-long ordeal into a relatively quick and successful recovery. The barely visible blood trail that we struggled to follow with traditional flashlights appeared like a glowing path through the Thor 4, leading us directly to the downed deer in a matter of minutes.
Durability and Reliability in Challenging Conditions
Hunting often takes us into harsh environments, and any piece of gear needs to be able to withstand the elements. The ATN Thor 4 640 is built to meet these challenges head-on. Its rugged construction has held up admirably through rain, snow, and the inevitable bumps and knocks that come with traversing rough terrain. The weather-resistant design means you don’t have to baby this scope, allowing you to focus on the hunt rather than worrying about your equipment.
Battery life is another area where the Thor 4 shines. With up to 16 hours of continuous use on a single charge, it easily outlasts even the longest hunting sessions. This extended battery life is crucial when you’re miles from the nearest power source, ensuring that your scope won’t die at that critical moment when you need it most. During a weekend-long hog hunting trip in Texas, I was able to use the scope extensively each night without needing to recharge, a level of reliability that’s invaluable in the field.
