Armasight Sidekick 640 1x19mm Thermal Monocular Review

First Impressions of Armasight Sidekick 640 1x19mm Thermal Monocular

The Armasight Sidekick 640 1x19mm Thermal Monocular enters a market saturated with thermal imaging devices, promising a potent combination of compact size, high resolution, and user-friendly operation. Offered by Armasight, this monocular boasts a 640×480 resolution, a fast 60Hz refresh rate, and the ability to record video, all in a package weighing under 250 grams. My initial reaction was a blend of excitement and skepticism – could such a small device truly deliver the performance I expect from a professional-grade thermal imager?

As a seasoned outdoorsman and tactical gear enthusiast, I’m always on the hunt for tools that enhance situational awareness and provide a tactical advantage. My primary need was a compact thermal imager for nighttime surveillance during search and rescue operations, and for wildlife observation without disturbing the natural environment. The Sidekick’s small form factor and potential for helmet mounting caught my eye, as did the positive customer feedback regarding Armasight‘s customer service.

The unboxing experience was straightforward; the Armasight Sidekick 640 1x19mm Thermal Monocular came securely packaged with a lens cloth, product manual, soft case, two CR123A batteries, and a USB-C cable. Holding the monocular for the first time, I was immediately impressed by its lightweight and ergonomic design; the ULTEM Composite Body felt robust and comfortable in my hand. The build quality seemed excellent, though the USB protector already felt a bit loose, confirming one user’s concern.

Compared to my older FLIR Scout TK and a larger, weapon-mounted thermal optic from another manufacturer, the Sidekick offered a compelling middle ground. The FLIR was cheaper but lacked the resolution and advanced features, while the weapon-mounted optic was too bulky for casual scouting. I ultimately chose the Sidekick for its balance of portability, resolution, and recording capability, and the advertised 60Hz refresh rate was a significant selling point.

My initial impression was cautiously optimistic; the Armasight Sidekick 640 1x19mm Thermal Monocular seemed to have the potential to meet my needs, but real-world testing would determine if its performance matched the hype. The first impression was positive, but I needed to see how it fared in the field before making a final judgment.

Real-World Testing: Putting Armasight Sidekick 640 1x19mm Thermal Monocular to the Test

First Use Experience

My first field test of the Armasight Sidekick 640 1x19mm Thermal Monocular took place during a nighttime wildlife survey in a heavily wooded area known for its deer and wild hog populations. I wanted to observe their activity patterns without disturbing them, and the thermal imager offered a non-invasive way to do so. The temperature was cool and damp, presenting a realistic test of the device’s capabilities in challenging conditions.

The Armasight Sidekick 640 1x19mm Thermal Monocular proved remarkably easy to use right out of the box; the three-button control system was intuitive, allowing me to quickly cycle through the different color palettes and adjust the image. The high-definition 1024×768 OLED display delivered a crisp, clear image, and the 60Hz refresh rate provided smooth, fluid movement even when scanning quickly. Within minutes, I was spotting deer grazing in the distance and identifying heat signatures of smaller animals hiding in the underbrush.

One initial surprise was the limited battery life; the included CR123A battery lasted only about an hour, significantly less than I had hoped. Another minor issue was the image clarity in dense fog, which required careful adjustment of the image settings to achieve optimal visibility. Despite these minor drawbacks, the Armasight Sidekick 640 1x19mm Thermal Monocular performed exceptionally well, revealing a hidden world of nocturnal activity that would have been impossible to see with the naked eye.

Extended Use & Reliability

After several weeks of regular use in a variety of conditions, the Armasight Sidekick 640 1x19mm Thermal Monocular has proven to be a reliable and versatile tool. I’ve used it during nighttime security patrols, search and rescue training exercises, and even during daylight hours to identify heat signatures obscured by foliage. It has consistently delivered excellent thermal imaging performance.

In terms of durability, the ULTEM Composite Body has held up well to the rigors of field use, showing no signs of cracks or damage despite being subjected to bumps, scrapes, and exposure to the elements. The lens has remained clear and scratch-free, and the monocular continues to operate flawlessly even after being exposed to rain and dust. The Sidekick is rated to IP67 Water Resistance Level, making it resistant to dust and immersion between 15 centimeters and 1 meter.

Maintaining the Armasight Sidekick 640 1x19mm Thermal Monocular is simple; I just wipe the lens with the included cloth after each use and occasionally clean the housing with a damp cloth. Compared to my previous experiences with other thermal imagers, the Sidekick offers a superior combination of performance, portability, and ease of use. It has exceeded my expectations in almost every way, making it an invaluable tool for my outdoor and tactical needs.
