What do these specs mean?

Understanding Thermal Specs

Thermal Resolution

Think of this like a TV screen (e.g., 1280x1024). A higher number means more pixels. More pixels give you a sharper, more detailed image, allowing you to digitally zoom in much further before the image gets blurry or pixelated.

Thermal Lens

Similar to a camera lens, measured in millimeters (e.g., 50mm). A larger lens gathers more thermal energy and "sees" further, giving you a longer detection range. However, larger lenses typically result in a narrower field of view.

Pixel Interval (Pitch)

The physical distance between pixels on the sensor, measured in microns (e.g., 12µm). A smaller number means the pixels are packed tighter together, which produces a crisper image and extends your optical magnification without needing a massive lens.

NETD (Thermal Sensitivity)

Measures how tiny of a temperature difference the device can detect. Lower is better (e.g., < 15mK beats < 25mK). A lower NETD means you get a much clearer picture in terrible weather (rain, thick fog, high humidity) and superior contrast between the animal and its surroundings.

Thermal FOV (Field of View)

How wide of an area you can see at once. A wider FOV is excellent for scanning large areas quickly to spot movement. A narrower FOV usually means the device has higher magnification, perfect for identifying specific targets at long distances.

Understanding the Math

We believe in honest, real-world field specifications.

Detection ranges are calculated by taking the manufacturer's baseline testing and physically scaling it to the average height of the target animal.

Recognition & Identification are calculated using Johnson's Criteria—the military standard for thermal optics. By analyzing the physical properties of the camera's lens and sensor pitch, we calculate exactly when the target will take up enough pixels on your screen to be clearly identified.

Note: High humidity, thick coats, and environmental background temperatures will reduce these maximum optical distances in the field.

Product Overview

RIX Pocket K2: The Ultimate Every Night Carry (ENC) Entry Point

The RIX Pocket K2 is designed for the user who needs the "superpower" of thermal vision in a package that never leaves their side. Weighing just 200g, the K2 is the lightest professional thermal monocular in the RIX lineup, specifically engineered to be an essential part of your Everyday Carry (EDC) kit.

Whether you are a homeowner conducting a perimeter check during a power outage or a security professional needing a wide-angle view of a dark parking lot, the K2 provides rapid, reliable heat detection in a frame no larger than a standard smartphone.

Wide-Field Observation & Close-Quarter Detection

Equipped with a 9mm objective lens and a 256x192 (12μm) sensor, the K2 is optimized for a wide field of view (19.4°×14.6°). This makes it superior for scanning large areas quickly at close-to-mid ranges. With a detection range of 468 meters and a sensitive <25mK NETD rating, the K2 ensures you see heat signatures through smoke, light fog, and total darkness.

Compact Reliability Without the Compromise

Small size usually means low performance, but the K2 breaks that mold. It features a smooth 50Hz refresh rate and a high-contrast 800x600 OLED display, providing fluid motion tracking and vivid palettes. Like its larger siblings, it utilizes a replaceable 18650 battery, ensuring that you are never sidelined by a dead internal battery—simply swap and continue your mission for another 6 hours.

The Strategic Advantage

The RIX Pocket K2 is the tool for those who believe that "having it and not needing it is better than needing it and not having it." It is a no-nonsense, professional-grade thermal imager that provides the essential clarity needed for daily situational awareness and nighttime security.
