Just when you thought the ThOR HD range from ATN was the best range of thermal scopes, a new series emerges. The ATN ThOR 4 series is the latest upgrade from the HD range and offers even more advanced features.
The ThOR 4 (introduced in 2018) from ATN takes all the features that the ThOR HD series had and improved on them as well as adding some new ones. A couple of the biggest ones are dual streaming video through WiFi, social media sharing, 16+ hours of battery life and up to 64gb of storage with an microSD card. This is in addition to all of the features they have become known for with their HD line including:
- Ballistic Calculator
- Recoil Activated Video (RAV)
- One Shot Zero
- Profile Manager
- Smart Range Finder
- Dual Core Processor
- Smooth Zoom
ATN which was started in 1995 is one of the most prominent companies in the thermal imaging and night vision space catering to hunters, outdoor enthusiasts, law enforcement and many others. They offer a variety of thermal and night vision scopes, monoculars, binoculars, and clip-on scopes. They also offer a range of thermal imaging resolutions in their thermal scopes and monoculars from 160x120 to 640x480 which means you can find what you need no matter your budget.
Just like the ThOR HD the ThOR 4 line has several optics options to choose from as well as thermal resolutions which means you can find the perfect model for your needs and budget. We were able to test and review two of the ThOR 4 scopes, the 640x480 1.5-15x (this review) and 384x288 2-8x which you can find here.
Key Features of the ATN ThOR 640
Thermal Resolution
The ThOR 4 640 thermal riflescope is equipped with an ultra-sensitive Gen 4 sensor. Simply put; you can expect the unit to capture clear and crisp images because of the high 640 x 480 thermal resolution. This coupled with the 1280x720 HD display is one of the best on the market currently.
Thanks to the superior sensor, the quality of images aren’t compromised even if you’re viewing from afar or zooming in. Images are also clear whether you’re using it in no or low-light situations which is what you want from your thermal scope.
Wi-Fi Streaming & Video Recording
We mentioned that you can stream footage onto your device. For your convenience, you can use this thermal scope to stream on both iOS and Android devices, making it versatile and relevant to almost all mobile users. ATN's Obsidian App is extremely easy to setup and use and you can adust all the scopes setting directly from the app which is a great feature.
With the click of a button you can easily capture images or video with no need to go into the systems menu to change to the camera or video recording mode.
Refresh Rate
The ThOR 4's 60Hz refresh rate (and recording rate) makes tracking moving targets, even fast ones very easy with no motion blur. For many hunters 30Hz is enough but you can truly see the different with a 60Hz refresh rate.
Digital Zoom
The ThOR 4 we tested had a 6x digital zoom which was very easy to use thanks the zoom wheel on the left side of the scope, which we talk more about below. The digital zoom allows you to get an even better shot after spotting your target if its further away.
One-Shot Zero
By picking this mode, you eliminate the hassle involved with sighting in your scope; a problem often associated with other brands. Thanks to the One-Shot Zero feature, you simply take a shot, adjust the reticle to where the bullet hit the target and save the settings. This greatly reduces the amount of time you need to spend sighting in your scope.
Easy to Use Navigation/Menu System
Novice hunters will particularly be impressed by how user-friendly this device is. Navigating through the different functions of the system menu will be pretty straight forward thanks to the intuitive menu layout and minimal button inputs needed to toggle features on or off. You can also use ATN's Obsidian app to navigate and change settings directly from your phone or tablet.
Recoil Activated Video
Again, if you’re new to hunting, this scope is designed to make life
