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.

ARMASIGHT Zeus-Pro 640 4-32x100 (30 Hz) is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Amazing tool to increase the hunting experience.. Very easy and intuitive menu set.. lots of useful options. Video quality is spot on. Zoom at 4x&8x gets real pixelated and distorted as expected with digital zoom. Point of Impact steady on all zoom settings. Picked up the a field mouse heat signature over around 150 yards. Deer over 1000 yards with good identification. Does get barometric saturation and must NUC a lot during wet hunts. Would HIGHLY recommend the extended battery pack with rechargeable Samsung batteries as they will go all night. Surefire set lasts a couple hours of intermittent use and gets pricey. Customer service has been great. Have an issue of the scope powering down/resetting after recoil though.. Worked good initially but issue just started, no fix as of yet. Others have the same issue. Difficult to upgrade software due to sending back to the factory for weeks/months without scope. Built rock solid though. Tough to use on standard rifle with long stock due to getting eye on viewfinder. Best with collapsible stock.. Sits high on rifle as well so get use to new shooting position. Wish I would have purchased a Thermal years ago.. Can't live without it now when you can see EVERYTHING that is moving at night and do not have to wonder what it is, squint for identification or just flat out miss it because you didn't see it. You can see animals standing in the woods that you are not able to see with the eye or the best optics. Just amazing.. So start saving as the price is the downfall.

Rated 5 out of 5 by from The best thermal imaging scope on the market! When I got my new GAP Hospitaller last year I started to use my older Sako TRG less and decided to make that a dedicated night vision weapon. I choose thermal mainly because if needed I still can effectively engage targets in the day time. From my service days I knew that thermals are very expensive and if you wanted the top of the line BAE or L3 you might need to set a $20,000 budget, or even larger than that. With that budget I wanted to make sure that I was getting the best. I had field tested in six months 11 high-end scopes from five manufacturers. I even travel out of state twice just to try some gear. I picked Armasight Zeus Pro 640 100mm based on the following in the order of importance: 1. Overall image quality. 2. Accuracy, repeatability, zero-hold. 3. Overall Ruggedness of construction. 4. Maximum engagement distance. 5. Manual NUC 5. Manually focus on front lens. 6. Long, comfortable eye relief. 7. Laser Range Finder option. 8. Warranty 9. Reticle choices. 10. Color pallets. 11. Other features While some of the above does not require explanation I would like to explain a few things. First is a manually adjustable front germanium lens is a must. There are some of the scopes out there with so called electronic focus or e-focus or digital focus. To me it's a gimmick that never works right. Well, I'll take that back. It will work in some particular setting on the given target, but in the real life it's not a good way to go simply because the whole thing works only if you have one target in your FOV and that target better have significantly different thermal signature than a background. With e-focus as soon as you have two targets or if surroundings are similar temperature as the target (think really hot day or cold rainy day) the scope gets confused. It is really apparent why some scopes don't have a manual focus lens. I talked with few companies and all told me that making big lenses from germanium so that mechanics and optics precise and hold recoil is very expensive, this is why scopes with no-manual front focus are cheaper. Second, eyepiece optics must have long eye relief. I have seen some scopes using PVS-14 (a monocular designed to be head mounted). That's just a recipe for fiddling and scope bites. Third, if you are getting your NV scope for long range bolt gun your Terrapin will be useless at night, so think of LRF option. Next, ANY TI scope will get barometer sensor saturation and you will need to NUK it. Armasight makes best NUC - it's mechanical. It will go off every 5 minutes or so and will give you warning or you can simply manually NUK the scope by pushing two buttons (up & down) at the same time. Even more, you can do the same with buttons on wireless remote control, so you get pristine target picture anytime you want, barely moving the fingers. NUK or calibration on other scopes is a pain. You usually need to close the cap to do it and then wait for five seconds for NUC to go off and then remove the cap. And all "electronic NUC" or e-calibrations or silent NUC are basically worthless. Although in the beginning you might think color pallets are useless because you always end up using white/hot or black/hot you might be wrong. After few practices you will find out that depending on target (steel,paper or organic) and surroundings (ambient temperature, brush, wet sand, wet grass, snow) color pallets might be really cool thing to use for some scenarios. I shot about 800 rounds of .308, almost 300 rounds of .300WM and about 80 rounds of .336 Lapua with it. Longest shots on warm steel, so far right around 800-830 meters. This scope should be capable going 1,200-1,300 meters and further in good hands. I just did not have a space to stretch my legs that far. So far had no problems. Mount gets sticky sometimes when it goes from platform to platform. It's ok mount but there are many better mounts out there. One thing I am still not sure if I should of gotten a 50mm lens instead of 100mm. You can really tell the difference in picture quality (magnification/FOV is obviously twice larger/smaller) after really long distances. It's not even a cost difference, but 100mm is way heavier than 50mm. On the negative side are obvious things that come with long range thermal its big and heavy. Also I noticed that mount gets sticky when I move scope from gun to gun. I spent less than half of my original budget on this scope, but still I could buy 3 S&Bs for that kind of money. Armasight keeps coming up with newer software versions all the time. I wish there was a way to upgrade the scope soft without sending it back to the factory in California. Couple last points. You can get better picture with ether larger lens or with core that has smaller pixels on the sensor (like 12 micron is better than 17), but doing with the larger lens is better way of doing it. Last, a lot of people think that 60Hz Is always better than 30Hz simply because it cost more. 60Hz was design to do one thing better, see/shoot fast moving target. Not just fast moving car, but rather fast moving car observed from flying copter. If everything else is the same 60Hz will give worst picture than 30 Hz, because 60Hz you just don't get enough heat on the sensor before sending info to camera brains. Too slow is not good. 9 Hz is useless. 30Hz is a sweet spot. Overall Armasight Zeus Pro is an outstanding piece of gear. Buy with confidence. Save up and get the best.

I am having trouble selecting a reticle on my Zeus pro 50mm. Any help?  Thanks

Asked by: jyj0228
try doing the long hold on the left button. if that does not work place the cap on the scope enter the menu and select the reticle manually

Hey there, is the Zeus Pro able to be shipped to Canada? Thanks a bunch, Sean

Asked by: CaptSean

I would like to use rechargeable 1.2 V batteries (size AA). Does this work? Or can I use CR123 recharageable 3,7 V battieries (4)? I can not find anything in the manual about rechargeable batteries. Im using the Zeus Pro 640 4-32x100.
