Guide TU425SE 3.0 Thermal Viewfinder

The Guide TU425SE 3.0 is an ultra-compact LPVO-style thermal viewfinder that combines a next-generation VOx sensor with AI-driven imaging algorithms and shutterless design to deliver smooth, high-detail displays. Its standard 30mm snorkel chassis makes it easy to mount like a traditional riflescope, while ergonomics with focus wheel and zoom lever allow for intuitive control. With IP68 protection, 6000 J impact resistance and dual battery system (built-in + hot-swappable external 18650) for up to 12 hours of use, it is a robust solution for hunting, wildlife monitoring and professional use.

Features

• LPVO style, small size: ultra compact housing with standard 30mm snorkel for conventional mounting.
• Premium AI imaging: hyper-light algorithm with higher clarity, lower noise and better micro-contrast.
• Shutterless 3.0: no clicking and freezing; continuous display during calibration.
• Field ergonomics: focus wheel, zoom lever and buttons optimized for natural operation.
• Extreme ruggedness: IP68, recoil resistance up to 6000 J (1200 G).
• Inexhaustible power: built-in 18500 battery + external 18650 with hot-swap; up to 12 h.
• Shot-activated recording: automatic 15 s video capture and 5 photos after each shot.
• Hunting assistants: BTC (center reticle), AI (contour detection, identification), TargetIR Ballistics app with database and ballistic calculator.
• Modern connectivity: dual band Wi-Fi, Bluetooth and USB-C for power and transfer.
