Guide TU435S Thermal Scope

The Guide TU435S Thermal Scope is built for medium-to-long-range spotting and observation, combining a 35mm objective with the APEXVISION infrared imaging system to deliver clearer thermal images at distance.

• 400 × 300 @12μm thermal sensor with <15mK NETD sensitivity — supports improved contrast and detail in challenging conditions.
• 35mm lens and a stated detection range of up to 1800 metres — tuned for extended-range target detection and situational awareness.
• Shutterless design and IP68 waterproof rating — engineered to operate reliably in wet or dusty environments without a mechanical shutter.
• Dual-band Wi‑Fi and easy-to-use controls — provide on-device operation and wireless connectivity for streaming or remote viewing.
• Includes quick release scope mount (torque setting <2.5 N·m / 22.13 in-lbs) — allows mounting and removal without additional hardware adjustments.

Purpose-built for users who need robust thermal performance at distance, the TU435S pairs a high-sensitivity sensor and a medium telephoto lens with durable construction and wireless features to support field use in varied conditions.
