GUIDE TU425S Thermal Scope 400x300

The GUIDE TU425S is GUIDE's compact entry point into the APEX VISION infrared imaging system — delivering next-generation AI-powered thermal performance in a short, lightweight tube scope built around a 400×300 sensor and 25mm lens. With NETD <15mK sensitivity, a fast F1.0 aperture, and detection out to 1,300 metres, the TU425S is purpose-built for close-to-mid-range hunting where a compact, manageable optic matters as much as the image quality. A conventional zoom ring at the eyepiece means it handles exactly like a traditional daytime scope — right out of the box, complete with a quick-release (QD) scope mount.
