The Guide Thermal Riflescope TU435 LRF 3.0 400x300 brings a modern thermal imaging package to your rifle in a compact 30mm-tube optic. Built around a 400x300 VOx sensor and a bright 35mm F1.0 objective lens, it delivers clear, high-contrast images on a crisp 0.49" AMOLED 1920x1080 display. Base 4.4x magnification with smooth digital zoom out to 17.6x, plus an integrated 1,630-yard laser rangefinder, helps you identify and range targets with confidence in challenging light.

This model is tailored for hunters and shooters who spend long hours in the field, combining a lightweight housing with intuitive controls, multiple color palettes, and generous 48mm eye relief. The dual-battery system (internal 18500 and external 18650) offers up to 12 hours of runtime, while IP68 sealing and a .300 Win Mag recoil rating keep the scope running in harsh weather and on hard-kicking rifles. It is an excellent choice for night hunting, predator control, and extended-range observation, backed by Guide’s focus on practical innovation in thermal optics.
