TS-31 / LRF Thermal Night Visor

Reference: PAE

No taxes

without rangerfinder


The new Pard TS-31 sight has a traditional sight exterior but is a multifunctional night and thermal sight with cutting-edge technology.

Ultra-clear 800*800 IPS Display

Thermal imaging can be displayed on the screen with Picture-in-Picture (PIP) function, providing a clear heat signature, greatly enhancing viewing comfort.

Higher image quality

Reduced visual fatigue

Long Eye Relief for Guaranteed Viewing Comfort

Lens options, each with a 100mm eye relief, offer a wide field of view. There is a rubber eyepiece to provide covert observation at night while maintaining the user's habit of using traditional daytime optics.

Clear field of view

Extended and enjoyable viewing

Circular Design in the Scope

The circular screen design allows for a full circle of the image. With a wide field of view (FOV), sight centering adjustment after zeroing helps you get a great idea of where the target is in relation to the surroundings.

Wider field of view

High Sensitivity 12 μm LWIR Sensor

With a resolution of 384x288 pixels or 640x480 pixels and a 12 μm vanadium oxide (VOx) sensor, NETD ≤25 mK, and a 12 μm pixel pitch, users can enjoy rich contrast and bold resolution when acquiring targets.

High-contrast thermal images

Extreme sensitivity

Enhanced object identification

Fast 1000m LRF Detection

Targets can be detected up to 1000 meters away. The newly developed compact range module is accurate and has fast detection speed. When combined with integrated ballistics, the LRF provides you with the range information you need for smarter night hunting.

Precise target range

Reduced image distortion

Lag-free imaging

Precise Ballistic Calculator

The integrated ballistic calculator can calculate bullet trajectory parameters such as velocity, bullet weight, and zero range. Improve your accuracy by calculating precise aiming points for your next shot location.

Multiple Objective Lens

The available 25/35/45mm optical objective lens provides hunters with a wide field of view. Suitable for different hunting environments; the smaller the field of view, the farther you can see.

Precise target range

Smarter hunting

Infrared Image Enhancement Algorithm (IREA)

The TS3x uses patented software and a next-level image enhancement algorithm to provide high infrared spectrum sensitivity values to improve image visibility. IREA enhances the overall image by reducing image distortion and enriching the level of detail, even for distant targets.

Better target recognition

Reduced image distortion

Lag-free imaging
