Sidekick Pro Mini Thermal Monocular: The Compact Thermal Imager for Handheld & Mounted Operations 

• The Armasight Sidekick Pro Mini Thermal Monocular is an ultra-compact observation and navigation tool built for handheld scanning and helmet-mounted operations. Designed and assembled in the USA, this device delivers high-resolution thermal imaging to help you spot targets in the dark, through dense fog, or hidden by camouflage. Weighing just 254 grams, it provides professional-grade situational awareness without straining your neck on long missions.
• Detect Human Targets Up to 775 Yards Away: The 12-micron ArmaCORE sensor reliably picks up distant heat signatures. With a thermal sensitivity rating of under 20mK, the device highlights tiny temperature differences in heavy rain or deep fog. This extreme sensitivity prevents the screen from washing out during bad weather.
• Track Moving Targets at 60 Frames Per Second: A fast 60Hz refresh rate stops motion blur and stuttering when you pan the device quickly across a field. The thermal data is shown on a crisp 1920x1080 Full HD OLED screen. This provides sharp, clear details that match how your eyes naturally see, which is vital for moving while the unit is helmet-mounted.
• Operate for Up to 5.5 Hours on Two Batteries: Using the included battery extender, the device runs on two standard CR123A batteries for long patrols or hunting trips. For extreme cold weather or long stationary watches, you can also plug it into an external power bank using the built-in USB-C port.
• Survive Deep Water and Extreme Cold Down to -40°F: Built from a tough ULTEM polymer, the monocular is highly durable while staying extremely light. It holds an IP67 waterproof rating, meaning it can survive completely underwater for 30 minutes. The internal electronics continue working in harsh environments ranging from a freezing -40°F up to a blistering 122°F.

Helmet Mounting & Dual-Band Fusion Integration for the Sidekick Pro Mini

• Built-in Dovetail Mini-Rail: Molded directly into the lightweight ULTEM chassis, this integrated rail allows for direct attachment to helmet hardware, completely eliminating the need for heavy, bulky wrap-around mounting rings.
• Rayvn Group Modular Bridge Mount: A highly recommended bridging solution (sold separately) that allows you to helmet-mount the thermal monocular alongside a PVS-14 night vision device or a second Sidekick. This specific mount requires no extra adapter arms and offers infinite lateral adjustment, making it easier for your brain to fuse the thermal and night vision images.
• Noisefighters RMAX14 or MRX-PRO: These specialized articulated helmet arms interface seamlessly with the built-in mini-rail for a single-eye thermal deployment. They click securely into standard dovetail helmet mounts.
• Wilcox G24 Helmet Mount: Mentioned as the industry standard, this mount serves as the reliable base interface on your helmet for attaching articulated arms and keeping the optic secure during rapid movement.
• Noisefighters Panobridge: A widely used alternative bridging system for dual-band setups. While highly effective, it requires a separate mini-rail arm accessory to properly interface with the Sidekick Pro.

Sidekick Pro Mini Thermal Monocular FAQs

What is the Sidekick Pro Mini Thermal Monocular used for? 

It is a very small and light tool that lets you see heat in the dark. You can hold it in your hand or attach it to your helmet. It helps you see people, animals, and objects at night, in thick fog, or hidden in bushes.

Thermal Scope vs Monocular, what is the difference?

When looking at the differences of a thermal scope vs monocular, it helps to know how each device is built and what job it is made to do. Both use the same basic technology to show you heat in the dark, but their designs serve two very different purposes.

• What is a Thermal Monocular? A thermal monocular is strictly designed as an observation, scanning, and navigation tool.It is built to be lightweight and portable, meant to be used as a handheld device or mounted to a helmet. It usually has a wider field of view so you can see more of your surroundings at once to maintain situational awareness. It does not have crosshairs for aiming, and it is not built to survive the heavy recoil of a firearm.
• What is a Thermal Scope? A thermal scope is engineered to be mounted directly to a rifle and function as a standalone weapon sight. It is built with heavy-duty materials and specific recoil ratings to handle the harsh physical kick of a firing gun. A scope includes an internal digital reticle (crosshairs) so the user can accurately aim at a target. Because it is focused on aiming at a distance, a scope typically has a narrower view than a monocular.

How is the Sidekick Pro 640 different from the older Sidekick 640? 

The new Pro model gives you major upgrades to the screen and processing power. It changes the older 1024x768 screen into a huge 1920x1080 Full HD display so you get a much clearer picture. It also adds a fast 1.8 GHz processor and a smart AI chip. These new upgrades fix video lag and make your targets look much sharper during bad weather like heavy rain or fog.

Can I wear it on my helmet? 

Yes, you can. It has a built-in rail that snaps into many common tactical helmet mounts. This lets you walk around and scan the area without using your hands.

Can I use it on a rifle as a scope? 

No, you cannot use it on a gun. It is not built to handle the kick or recoil of a firearm. It is only meant for looking around, scanning areas, and finding your way.

How long does the battery last? 

If you use one battery, it lasts for about 1.5 hours. But the package includes a special battery extender. When you use the extender with two batteries, it can run for up to 5.5 hours.

How far away can I see a person with this? 

You can spot the heat of a human-sized target up to 709 meters away. That is about 775 yards.

Is this device waterproof? 

Yes, it is very tough. It has an IP67 rating, which means no dust can get inside. It can also survive underwater up to 1 meter deep for 30 minutes without breaking.

Can I use it alongside my night vision goggles? 

Yes, this is one of its best features. You can wear the thermal monocular on one eye and night vision on the other. It even has a special software setting to perfectly line up the thermal image with your night vision view.

Does it record video? 

Yes, it has a built-in video recorder. With the push of one button, you can record crisp video of what you are seeing, and it even records sound.

Where can I buy the Sidekick Pro Mini Thermal Monocular? 

You can buy the Sidekick Pro directly from Atomic Defense. We offer the best prices and all the mounting accessories you need to complete your tactical helmet setup.
