The ATN Thor 640 weighs 1.85lbs which makes it suitable for easy carriage, well, unless of course, 1.8lbs is quite heavy for you. It has a magnification minimum of 2.5x and a magnification maximum of 25x. When it comes to the zooming aspect, this monocular performs smoothly; less grains and good eye on the subject. Meaning you can increase your level of focus without losing sight of your focus point. The sensor on the ATN Thor 640 recognizes body heat rather than light. This technological advancement means that the night vision scope recognizes body heat of animals and provides important information about the target. One particularly endearing feature courtesy of the sensor is its human detection . It not only detects humans, but recognizes and identifies. A human can be detected up to 1500 meters away, recognized at 600 meters away and identified at up to 360 meters away. This particular feature can probably help to reduce the rate of accidental murders. The THOR 640 is powered by obsidian core of scopes that are above conventional standard. It actually makes a billion cycles per second. This rifle scope is built to process large information quickly.

The battery power within the power pack of the ATN Thor 640 night vision scope measures up to 20000mAh. Fully charged, your device can function at its best capacity for 22 hours making it possible to be used for several hunting trips without needing to be charged.

Apart from just giving you a clearer view of your target and calculating distances, you can of course, record your escapades in video format. Videos are captured in HD format making sure that every second of your adventure is recorded. Apart from normal videos, the Recoil Activated Video (RAV) ensures that every accurate shot is recorded to the last detail. Videos recorded can be streamed to your phone or tablet through either Bluetooth or Wi-Fi. To do this, you will have to download the obsidian application. Simply download the app, connect your Thor rifle scope to your phone or tablet via either Bluetooth or Wi-Fi, and choose to either view simultaneously, or if you are interested in watching previously saved videos, check the gallery out. However, if steaming is not for you, there is a simpler option of a micro SD card.

The Ballistic calculator is another great feature of the ATN Thor. It is a modern technology that erases the need for charts, complex calculations, complex reticle and even experience. The ballistic calculator uses the accurate measurements of the distance between you and your prey given by the range finder to ensure you hit your target. After entering all the data pertaining to the environment that is required such as conditions of the atmosphere and weather, accurate feedback containing the distance is then given. The ballistic calculator also gives you accurate calculations in the trajectory of your bullet. Its calculations adjust your point of impact to improve the accuracy of your shot placement. Sounds cool? Yep. Coupled with the ballistic calculator, the Thor 640 comes with an ATN Laser Ballistics Smart Laser Rangefinder 1500. The job of this smart range finder is to find the distance between the prey and the predator. This job previously needed a whole different equipment to be performed. The range finder however eliminates the need for such devices. Knowing the distance between you and your prey allows you to make important decisions which will help you hit your target head on. A shooter with little or no experience will not need much except a range finder to improve the accuracy of shots within time. The functions of the ballistic calculator, smart range finder and other smart devices coming together in this device are all controlled by the ATN X-Trac Smart Tactical Remote Access Control which serves as the remote control. Adjustments, regulations and changes can be easily made without any complications at all from the ATN X-Trac Smart Tactical Remote Access Control.
