The Zeus Pro family of Thermal Weapon Sights showcases the best and latest advancements developed by Armasight in the field of uncooled thermal imaging technology for the dismounted soldier, special law enforcement team member, and professional hunter. The Zeus Pro epitomizes Armasight’s 20/50 design gold standard, which is defined from product inception as being capable of withstanding 20 meters immersion for 2 hours and engineered for routine use with 0.50 BMG weapon shock and recoil. Based around common core electronics, signal processing, and eyepiece optics with generous eye-relief, the Zeus Pro Series Thermal Weapon Sight is available in a variety of options and price points that cater to every application – military and commercial.

Utilizing the latest FLIR TAU-2 Technology, the Zeus Pro is offered in 336x256, or 640x512 pixel formats. These options are further enhanced by professional militarygrade 30mm, 50mm, 100mm Germanium (Ge) objective lenses creating a wide variety of optical magnifications and range performance capabilities that the customer can select from. Armasight has introduced a unique dual battery option for the Zeus Pro Thermal Weapon Sight consisting either of four 3.0V DC CR123A batteries all oriented in the same direction to prevent confusion in replacement, or four 1.5V DC AA batteries pre-loaded in a cartridge. In a pinch, a single CR123A 3.0V DC battery can power the Zeus Pro for just over one hour.

The Zeus Pro Thermal Weapon Sight is characterized by its simple and intuitive controls, functions, and features that are layered among direct button adjustments, direct combination button functions, and electronic menu selections. In an effort to better support the art of shooting, Armasight has included ballistic drop reticles, electronic compass and inclinometer in the Zeus Pro package for finer range estimation and target orientation. The Zeus Pro uses a 9-pin multi-pin connector to provide videoin imagery, where there may be a need for map or rangefinder display overlays, and external power access. In support of these capabilities, Armasight offers an optional laser range finder, external battery pack, multispectral laser and other accessories designed to attach on the MIL-STD-1913 rail of the Zeus Pro. Solid state technology reticle adjustments and software algorithms, combined with a complementary color reticle platform, ensures maximum reticle contrast, high level target accuracy, and boresight retention. This level of accuracy is translated into the tracking electronic zoom (e-zoom) function of the Zeus Pro thermal imaging weapon sights, which can be progressively increased from 1x to 2x to 4x and 8x without changing the point-ofaim to point of-impact relationship of the targeting reticle.

A five-button wireless remote switch is included to operate and modify the settings on the Zeus Pro to optimize the imagery for the viewed scene without having to remove your hands from the weapon. The Zeus Pro has Bluetooth© wireless capability and can directly interface with most smart phones with the potential for engaging a series of current and future applications.

The Zeus Pro Thermal Weapon Sight represents the most versatile and sophisticated Armasight product available in today’s market for hunters, SWAT teams, and military personnel, based on its superior price-to-performance value.

  • Special User-Adjustable Imaging Tools
  • Active Contrast Enhancement (ACE) – a digital “Contrast” correction that allows for a smart scene optimization based on dynamic adjustments where a variety of contrast levels occur depending on relative scene temperature.
  • Second Generation Digital Detail Enhancement (DDE) – a “Sharpness” correction that is digitally enhances the picture to present clearer imagery, significantly improves edge sharpening and further reduces image noise.
  • Smart Scene Optimization (SSO) – a fine-tuning computational correction that significantly improves an overall visual acuity for targets that have thermal signatures similar to a surrounding background.
  • Information-Based Histogram Equalization (IBHEQ) – a “Sky/Sea” enhancement – information based environment dependent algorithm that automatically adjusts camera gain and excludes pixels determined to not contain critical information, specifically helpful in scenes with lots of sky or water.
  • Automatic Gain Control (AGC) – a “Gain” correction that used to automatically adjust the gain to an appropriate range, the weaker the image signal, the stronger the gain.
  • User-Controlled Manual Non-Uniformity Correction/Flat-Field Correction (UCMNUC/FFC). There is a mechanical shutter between the camera sensor and the lens. This shutter is used to perform a non-uniformity correction (NUC) also known as flat-field correction (FFC. During FFC, the shutter presents a uniform temperature source to each detector element in the array. While imaging the flat-field source, the camera updates the offset correction coefficients, resulting in a more uniform image after the process is complete. All Zeus Pro models allow for user to manually trigger or interrupt scheduled UCMNUC/FFC function.
  • Silent Shutterless NUC ™ (SSN) – In addition to user controlled manual NUC/FFC all Zeus Pro models employ a digital supplemental non-mechanical flat-field correction that allows to extend the periods between mechanical shutter events and to further reduce image noise. SSN is always ON enhancement.

I have just acquired a ZP 100mm, 4x, 640(60) and am looking through all the new reticles (which are not in the manual).   Are there any detailed descriptions of these reticles?  Could you point me to these descriptions? Thanks. Joe

I would like to get a 4-32x100mm Armasight Pro. I am not sure if I need a 30 Hz or 60 Hz. Could you explain me the difference - I know that the picture repeats 2 times as often with 60 Hz, but do I need this? I am a hog hunter. thanks Steve

Asked by: Steve
60hz is for very fast moving scenarios which is why the refresh rate is nearly constant. these units are applicable to vehicle pursuits or other rapid engagement situations. For every hunting situation we suggest the 30hz as they will exceed any refresh rate needs during virtually any hunting scenario, and they use far less battery power to operate.

I am looking to buy the 640 pro possibly. I see it says can take a 50bmg. But can it take a 300 winmag as its constant weapon. They hit hard and just want to make sure it can take the abuse. Please respond so I can decide. Atn mil spec can't.

Asked by: Ben1

I had a chance to use one of your product lines Zeus 640 30hz. I'm in the debate whether to invest in 30hz or 60hz, I just want to understand the difference between the 2. Is the there any media or literature available on those differences? Thx

Asked by: Eric

Is the zoom 1x as well?
