GOYOJO GRS/GRL Series Thermal Riflescope for Hunting

The GOYOJO GRS and GRL Series thermal riflescopes help you scan your surroundings, spot heat signatures, and keep track of what you see in low- light conditions. Both series use an uncooled VOx thermal sensor and offer seven thermal color palettes, so you can choose a display that suits your preference and viewing conditions. The GRS series features a 256 × 192 sensor with 12 μm pixels, NETD <35 mK at 25°C, F/1.0, and a 50 Hz refresh rate. Its 25 mm objective lens provides a 7.0° × 5.3° field of view, with 3.5× optical magnification, 1×–8× digital zoom, and 65 mm eye relief. The GRS225 offers algorithmic ranging, while the GRS225RF adds a 905 nm infrared rangefinder with a range of up to 1,000 m (1,093 yd) and ±5 m accuracy, plus intelligent ballistic calculation. The GRL series offers a choice of thermal sensor resolutions: 384 × 288 on the GRL325 and GRL335, and 640 × 512 on the GRL635. NETD is <25 mK at 25°C, F/1.0 for the GRL325 and GRL335, and <20 mK for the GRL635. The GRL325 has a 25 mm objective lens and 3× optical magnification; the GRL335 and GRL635 have 35 mm lenses and 4× optical magnification. All GRL models offer 1×, 2×, 3×, and 4× digital zoom, 50 mm eye relief, and five reticle types with five color options. Both series include useful viewing and recording tools such as picture-in-picture, hot tracking, image enhancement, photo and video capture, and recoil-activated recording. RAV and Wi-Fi app support help you review and manage recorded media. Storage and battery life vary by model: GRS models include 32GB storage and provide approximately 7–9 hours of operation; GRL models include 64GB storage, with approximately 6–8 hours on the GRL325 and GRL335 and about 4 hours on the GRL635. Weather protection and recoil ratings also vary by series. GRS models are rated IP67 and tested to 800 g/0.4 ms; GRL models are rated IP65 and tested to 1,000 g/0.4 ms. Both the GRS and GRL Series are intended for commonly used rifle setups with recoil no greater than a standard .308 Winchester or 7.62×51 mm NATO setup, when properly installed. Do not use with higher-recoil magnum calibers, such as .300 Winchester Magnum or .338 Lapua Magnum. Recoil varies with the specific rifle, ammunition, and mounting configuration.
