The TOPDON TS003 Thermal Red Dot Sight is designed to provide clear thermal visibility and faster target acquisition in darkness and other challenging viewing conditions. Using thermal imaging technology, the TS003 detects heat signatures where traditional optical sights may have difficulty, including dark, smoky, and backlit environments.
The TS003 features a native 256×192 thermal resolution enhanced by TOPDON's TISR technology to 360×270, helping deliver greater image detail and clearer thermal target visibility. A 50 Hz refresh rate provides smooth image movement, making it easier to follow moving subjects.
Its 13 mm focal length is optimized for a 5–30 meter viewing range, providing a wide field of view for locating subjects efficiently. Users can select from 2 MOA, 32 MOA, and 64 MOA reticle options, along with four reticle colors and five thermal color palettes to adapt the display to different viewing conditions and preferences.
Operation is handled through a 1.41-inch touchscreen and physical buttons, providing convenient access to key functions. The TS003 also features simple zeroing controls and uses a standard RMR mounting footprint, allowing installation on compatible mounting platforms.
Built for demanding use, the TOPDON TS003 is designed to withstand up to 1200 g/s² of shock. It is backed by a 1-year warranty.
For users looking for a compact thermal sight with customizable viewing options, responsive thermal imaging, and an RMR-compatible mounting design, the TOPDON TS003 provides a practical solution for thermal observation and target acquisition.
