GRS225RF—Budget Thermal Optics With LRF

The Best Thermal Optics With LRF for Hunters and Tactical Enthusiasts

High-Sensitivity Thermal Sensor

The GRS225RF is equipped with a 12μm sensor at 256×192 resolution, NETD <35mK, and VOx technology, enabling clear imaging even in low-contrast thermal environments. With a 50Hz refresh rate, it ensures smooth tracking of moving targets during night operations.

Precision Laser Rangefinder

Integrated with a 905nm IR laser, the GRS225RF provides accurate distance measurement up to 1000 meters with ±1m accuracy. Perfect for long-range targeting, it ensures more confident shots in hunting or tactical scenarios.

RAV & Smart Connectivity

The GRS225RF features 32GB of built-in storage for easy photo and video capture. With Recoil Activated Video (RAV), recording automatically begins upon firing detection — ensuring you never miss a critical moment. Combined with Wi-Fi and App connectivity, users can view, manage, and share footage instantly, whether in the field or reviewing post-mission data.

One Shot Zeroing

The One Shot Zeroing function allows for quick and accurate alignment between thermal imaging and day/night vision modes. Simply take one shot using day/night vision, then easily switch to thermal imaging and adjust the reticle to the same point of impact (POI). Save your time and let you focus on your hunt.

Picture-in-Picture (PlP)

No longer a simple zoom, the PIP allows you to independently adjust the zoom level of the PlP image to improve shooting accuracy.

3.5-10x Magnification

The 25mm germanium lens offers 3.5× optical magnification with 1–8× digital zoom, delivering a perfect balance between field of view and target detail. Suitable for medium- to long-range observation.

4 Image Mode

Choose from four thermal color modes, including White Hot, Black Hot, Red Hot, and Iron, to suit various terrains, lighting, and tactical needs.

Crystal-Clear OLED Display

A built-in 1440*1080 OLED screen delivers vibrant, high-contrast visuals with fine detail. Whether scanning or aiming, the high-resolution display offers an immersive and accurate viewing experience in all lighting conditions.

Rugged and Lightweight Design

The compact and streamlined design of the Little Conch makes it lightweight and easy to carry and install for extended periods, while also withstanding up to 800g/0.4ms recoil for enhanced durability.
