10 Best Thermal Imaging Scopes 2025 in the United States

The AGM Global Vision Rattler V2 50-640 is a strong choice if you’re looking for a thermal imaging scope tailored for hunting. Its 640 x 512 resolution sensor and 50mm Germanium lens offer clear thermal images and a detection range of up to 2600 meters, which is excellent for spotting game at long distances. The 2.5x base magnification combined with up to 20x digital zoom allows you to identify targets with good detail, especially useful in various hunting environments.

Battery life is impressive, providing up to 9 hours of continuous use with rechargeable batteries, so you can stay out longer without interruption. The scope also includes handy features like multiple reticle options and shot-activated recording, along with user-friendly controls designed for easy operation even while wearing gloves.

The weight of just over 6 ounces and dimensions make it fairly compact but still somewhat bulky compared to lighter scopes, which might be a consideration if you prefer very lightweight gear. The polycarbonate material is likely durable enough for typical hunting use, but it’s not as rugged as some metal-bodied models if you expect very harsh conditions. This scope is well-suited for hunters who want high-resolution thermal imaging with solid range and useful technological features, though those prioritizing ultra-lightweight or the absolute toughest build might consider other options.

The Pulsar Thermion 2 LRF XP50 Pro Thermal Riflescope stands out for its impressive thermal sensor sensitivity, boasting a NETD of less than 25mK. This allows for exceptional detail recognition even in challenging weather conditions such as rain or fog, making it ideal for hunters who often work in less-than-perfect visibility. With a detection range of up to 2000 yards, it offers remarkable capability to spot targets from a distance, which is advantageous for long-range shooting. The scope's picture-in-picture mode is another notable feature, allowing users to zoom in on their target while maintaining an overview of the entire field of view—great for precision aiming. Additionally, the integration of Wi-Fi through the Stream Vision 2 app enhances user experience by enabling real-time image sharing and remote control of digital features from a smartphone.

On the downside, the scope does come with some considerations. Weighing in at 0.8 pounds and with dimensions of 16.5 x 3.09 x 3.72 inches, it has a compact build, though some users might find it a bit bulky depending on their rifle setup. Battery life is always a critical factor in thermal optics; longer outings may require extra batteries. Furthermore, the product is subject to export control regulations, which could complicate access for some potential buyers.

This riflescope is particularly suitable for avid hunters looking for advanced thermal imaging capabilities, but it's important to weigh these benefits against any potential drawbacks based on personal preferences and specific usage scenarios.

The AGM Global Vision Rattler V2 35-640 is a solid choice for hunters looking for a thermal imaging scope with clear and detailed visuals. Its 640 × 512 resolution sensor offers sharp thermal images, helping you spot targets up to 1800 yards away, which is excellent for most hunting situations. The 35 mm lens diameter and wide 12.5° × 10° field of view make scanning large areas easier, while the 2X base magnification adds flexibility without complicating use. One of the key strengths is its high thermal sensitivity (sub-20 mk), ensuring it performs well even in low-light or challenging conditions.

Battery life is impressive too, with up to 9 hours of continuous use from rechargeable batteries, allowing for long hunting trips without frequent recharging. Weighing just 6.34 ounces, it’s lightweight and won’t add much bulk to your rifle setup. The scope is built tough—waterproof and shockproof—and comes with an easy-to-use mount that allows quick detachment, which is handy in the field. It also includes useful features like multiple reticle options, shot-activated recording, and Wi-Fi connectivity via an app, giving you more control and convenience.

For hunters who want a reliable, easy-to-use thermal scope with good image quality and solid battery life, the Rattler V2 is a strong contender, especially given its feature set and durability.
