Introduction to the Armasight Zeus 640 2-16×42
Thermal imaging has come a long way in recent years. Nothing proves that more than Armasight’s Zeus series of thermal imagers, available in several models to suit anyone’s preference. Thermal imaging technology turns heat into a visible object seen on the scope, be it night or day – anything that emits some form of heat can and will be picked up by the sight. This is a far from the night vision devices of old that could only be used specifically during the night.
Made in accordance with Armasight’s dedication to high quality and excellent performance, the Zeus 640 2-16×42 is an impressive scope that provides a fantastic price-to-performance ratio. Take a look at this summary for a brief overview of this model.

The Armasight Zeus 640 2-16×42 is based on the latest FLIR Tau 2VOx microbolometer core. Primarily designed for firearms, this Zeus scope equally works well as a magnified spotting scope or a handheld thermal imager. This is the best in thermal imaging technology – it’s intended for both day and night use without having to dismount the scope from your rifle, and is a rugged, solidly-made device that will serve you well for many years.
The Zeus scope lets you cut through snow, dust, smoke, fog and haze to acquire your targets. Unlike laser targeting or near-infrared illumination in other kinds of night vision equipment, it is almost impossible for other devices to detect this scope because it emits no visible lights or RF energy. Advanced thermal imaging technology lets you see clear images even in the worst environments, which makes seeing and acquiring targets simple.
Several thermal imaging color modes, such as “rainbow,” which shows heat signatures in varying colors, or “black hot,” which shows warm objects in black silhouettes, provides you with plenty of options to choose from. These color modes can easily be customized according to your environment or your purpose. For example, hunters seem to prefer either the “black hot” or “white hot” settings because they pinpoint animals without the distraction of colors, but those using the sight to scan large areas might like the colored settings more.
Quick video demonstrations, such as the one shown above, show just how accurate and clear thermal imaging on this Zeus sight can be. A target set up 25 yards away with a thermal pack to indicate a heat signature was picked up by the scope – you can make out the lines on the target at that distance, suggesting that the ink might be warmer than the paper. This proves that anything with a modicum of heat can be detected by the scope’s ultra-sensitive mechanisms. Upon shooting, the bullet holes on the target were visible when viewed on the scope as well, as the discharge heated the bullets and friction from hitting the target emitted a detectable thermal image, as well.

Small and light, this Zeus scope has simple and intuitive controls, functions and features in its direct button adjustments and electronic menu selections. The control panel of the scope is placed on its top, making it very easy to see and manipulate. The layered control functions let you customize your preferences and maximize the built-in options available on the scope. For example, there are several reticles for you to choose from, like a single dot dead center or a full cross, so you can sight according to your specific taste. There are some special user-adjustable imaging tools available on the sight to better fine-tune accuracy. It’s very easy to adjust settings on the menu while shooting, keeping things flexible without compromising quality.
The ease with which the Armasight Zeus scope can be used makes it ideal for long-time gun users and beginners alike. It’s fairly simple to sight in the first time it’s used, and does not require overly long, complex tutorials to get the hang of. The scope has a quick release mount, so you can simply snap it onto a rifle and just as easily take it down.
The eyepiece on the scope is quite comfortable and blocks out ambient light when you look through it, which does not compromise the image and helps retain a sharp, clear quality.
The sight has a wireless remote switch that can activate operations when in “standby” mode. It also has video-out capabilities and a DVR for recording real-time footage or taking still photos. This is a useful feature for when you need rangefinder displays and external power access.
Perhaps the most pressing issue about the Armasight Zeus is its price. However, the cost of thermal imagers has radically dropped since they were first introduced in the twenty- to twenty-five-thousand dollar range, so the current retail price is fairly reasonable for its quality and number of features. It’s a solid investment, especially for those who see themselves using a thermal imager or night vision equipment of any kind frequently.
Armasight calls this Zeus scope one of the best and most sophisticated products in thermal imaging equipment, and has recommended it for use in law enforcement, military, professional hunting, as well as civilians who need full-performing sights. The Zeus cannot be bought by non-US citizens and is prohibited from being exported.
