When it comes to night hunting or tactical shooting, visibility is everything. The advancement of thermal technology has revolutionized how hunters and shooters operate in low-light or complete darkness. One of the most versatile innovations in this field is the thermal clip on scope, which allows users to attach a thermal imaging device to their existing optical scope without re-zeroing. Among the top contenders in the market are Pulsar, AGM, and Trijicon—each offering unique advantages for different types of users. This guide provides an in-depth comparison of these leading brands, highlighting performance, image quality, features, and overall value.

Understanding Thermal Clip-On Scopes

A thermal clip-on scope is designed to mount directly in front of your daytime optic, converting it into a powerful thermal imaging system. Instead of using visible light, it detects infrared radiation emitted by heat sources, allowing you to see targets through smoke, fog, or total darkness. These devices are popular among hunters, law enforcement, and military personnel due to their ease of use and ability to retain zero.

Thermal clip-ons differ from dedicated thermal scopes because they don’t replace your primary optic. This means you can use your regular riflescope during the day and attach a thermal imaging device at night, ensuring versatility and convenience.

Pulsar Thermal Clip-On Scopes

Pulsar has earned a strong reputation in the thermal imaging industry for its balance of innovation, reliability, and affordability. Models like the Pulsar Krypton FXG50 and Pulsar Proton FXQ30 are excellent examples of the company’s engineering prowess.

Key Features

• High-Resolution Imaging: Pulsar’s clip-ons often feature powerful 640×480 thermal sensors with advanced image processing, providing sharp and detailed visuals even in total darkness.
• User-Friendly Interface: The intuitive controls make it easy to adjust brightness, contrast, and color palettes without fumbling in the dark.
• Long Detection Range: Depending on the model, detection ranges can reach over 2000 yards, making it suitable for long-range shooting.
• Built-in Recording and Wi-Fi: Pulsar’s Stream Vision App lets users record, stream, and share footage directly to a smartphone or tablet.

Pros and Cons

Pros:

• Excellent image quality for the price
• Easy attachment and detachment system

• Digital Zero Retention: Trijicon’s precise alignment system ensures your point of impact remains unchanged after mounting.

Pros and Cons

Pros:

• Industry-leading image clarity
• Unmatched durability and reliability
• Excellent zero retention

Cons:

• Very high price point
• Slightly heavier than mid-tier options

Trijicon’s thermal imaging attachment systems are favored by military and law enforcement professionals but are equally beneficial for serious hunters who value precision and uncompromising performance.

Comparing Pulsar vs AGM vs Trijicon

When comparing Pulsar, AGM, and Trijicon, the key differences lie in price, performance, and target audience.

• Image Quality: Trijicon leads with its superior sensors and processing, followed closely by Pulsar and AGM.
