Guide TU 3.0 Series Thermal Imaging Rifle Scopes
The Guide TU 3.0 Series combines a familiar traditional riflescope profile with next-generation thermal imaging technology. Designed for hunters, wildlife-control professionals, and other qualified users, the series delivers a clear thermal image, intuitive operation, dependable recoil resistance, and extended field runtime in a streamlined metal housing.
Choose from the TU435S, TU635S, and TU650S. All three models use Guide's highly sensitive 12-micron thermal technology and Hyper-Light image processing, while the two 640-resolution models provide greater target detail and identification capability.
Key Features
- High-sensitivity thermal imaging: 15 mK NETD helps reveal fine temperature differences in fog, light precipitation, vegetation, and other challenging conditions.
- Hyper-Light image processing: Improves clarity, suppresses image noise, optimizes contrast, and enhances fine detail.
- Shutterless viewing: Guide's shutterless 3.0 technology eliminates calibration clicks and image freezing for a more continuous sight picture.
- Ergonomic scope-style controls: A focus wheel, zoom lever, and logically positioned buttons support fast, intuitive field operation.
- Lightweight metal housing: More than 200 g lighter than the comparable previous-generation configuration.
- Dual-battery system: Combines an internal battery with a replaceable standard 18650 battery. Hot swapping helps extend operation without shutting down the scope.
- Recoil-activated recording: Automatically saves a 15-second video and five photos when a shot is detected, with instant video playback.
- Rugged field protection: Rated IP68 for protection against water and dust and tested for recoil energy up to 6,000 J.
- Dual-band Wi-Fi: Supports wireless connection to compatible mobile devices through the Guide TargetIR app.
