Armasight has long been a trusted name in the world of cutting-edge thermal and night vision technology, delivering products that cater to everyone, from weekend hunters to professionals within the law enforcement and military communities. With the release of the Jockey 640 Compact Thermal Clip-On, the company continues its legacy of innovation, offering its customers a lightweight, easy-to-use solution for turning standard optics into thermal imaging systems. This optic isn’t just about impressive specs; it’s about practicality and performance in the field, giving users the edge they need when visibility is at a premium.

Dominate the Darkness: Armasight Jockey 640

The Jockey 640 is built around the ArmaCORE 640 thermal core, which, to put it simply, means that the inner workings of the unit ensure sharp, reliable imaging despite the tough conditions in which you may find yourself operating. With a 60Hz refresh rate, it provides smooth, consistent visuals, which are crucial for tracking moving targets in real-time. The device has a 640×512 resolution, delivering clear images to hunters so that they may distinguish between small details, like identifying game hidden in dense brush or spotting heat signatures from further distances.

Its adaptability makes the Jockey 640 such an appealing solution for seeing what goes bump in the night. Designed to clip onto the front of your preferred LPVO, it instantly transforms your existing optic into a fully functional thermal imaging system. It is important to note that the daytime optics you pair with this clip-on must be dialed down to 1x magnification and mounted in line with one another for proper viewing.

What does this mean to the end user? No longer are you required to dedicate a rifle to a thermal-only setup or fuss around with re-zeroing your scope. Whether you’re running a centerfire rifle for hogs, rimfire for varmints, or a number of other builds, the Jockey 640 offers hassle-free integration that complements virtually any platform.

Mounted ahead of a day scope, the Jockey 640 becomes a force multiplier in the field.

Easy Mounting Solution

Mounting the Jockey 640 is quick and easy with its quick-release system. Slap that baby on, and you’re ready to go! No one likes running gear that is complicated and time-consuming, so if you value simplicity and efficiency, you’ll be quite pleased. Once mounted, the thermal’s user-friendly controls allow for quick adjustments to suit changing conditions. Multiple display palettes such as white hot, black hot, and various colorized modes let you tailor your view, ensuring you can pick out the details you seek.

Another popular feature is the Jockey’s onboard video recording function, allowing you to preserve memories of a successful hunt to share with family and friends. The crisp OLED display allows for clear visuals and easy menu navigation, even while wearing gloves, with simple large navigation buttons located on top of the unit. Powered by two CR-123A batteries, the Jockey 640 can run throughout a long, demanding hunt or night-time range session.

For hunters who might be new to thermal imaging, the benefits of a clip-on device like the Jockey 640 can’t be overstated. Unlike standalone thermal scopes requiring dedicated rifles or frequent recalibration, clip-ons keep your existing optics and shooting setups intact. This approach offers the flexibility to switch between thermal imaging and regular daylight hunting without missing a beat. Additionally, the Jockey 640’s lightweight and compact design doesn’t add unnecessary bulk or weight to your rifle. This is a crucial factor for maintaining balance and accuracy, as well as minimizing the additional weight you’ll be carrying afield.

A rugged body protects the optics in the field.

Rugged Design

This clip-on thermal also excels in ruggedness and reliability. Built to hold up to the rigors and demands of outdoor use, it features a durable, water-resistant design that functions without issue despite what mother nature may be throwing your way. If you find yourself hiking into the woods on a damp morning or waiting out coyotes in sub-freezing conditions, this thermal is engineered to laugh in inclement weather. This thermal clip-on truly shines in its ability to expand your hunting opportunities. Low-light conditions, heavy brush, or weather-related visibility challenges are no longer barriers. The ability to detect heat signatures adds a new dimension to your hunts, allowing you to track game that might otherwise go unnoticed. Whether targeting hogs under the cover of darkness, scanning for predators at dusk, or ensuring nothing gets by you in thick terrain, the Jockey 640 will make your hunts more efficient and rewarding.

The Armasight Jockey 640 Compact Thermal Clip-On isn’t just another piece of gear; it’s a game-changer. Whether you’re an experienced hunter or just starting to explore the benefits of thermal imaging, this device provides the edge you need to succeed in the field while saving you countless dollars in the process. From its advanced thermal technology to its rugged, adaptable design, the Jockey 640 is a testament to Armasight’s commitment to delivering innovative solutions for hunters.

The clip-on design makes the Armasight Jockey 640 very versatile.
