The GUIDE TD421 and TD421 LRF thermal monoculars are designed for night observation, terrain surveillance, and animal location in low-visibility conditions. Both combine a 384 × 288 pixel 12 μm VOx sensor, a 25 mm objective lens, and a high-brightness AMOLED display in a compact and easy-to-handle body.
The TD421 prioritizes simplicity and portability, while the TD421 LRF adds an integrated laser rangefinder of up to 600 meters. The replaceable 18650 battery offers up to 10 hours of operation, and Wi-Fi connectivity allows for real-time image sharing via the TargetIR application.
Compact design with laser rangefinder
The TD421 LRF integrates a high-precision laser rangefinder capable of measuring distances of up to 600 meters without sacrificing a lightweight, portable, and durable body for field use.
High-brightness AMOLED display
The 12 μm thermal detector and 0.23-inch AMOLED display offer a high-contrast image with defined edges and comfortable viewing, even during prolonged observations.
Enhanced image processing
Optimization algorithms adapt scene processing to observation conditions to render both the target and the background with greater clarity.
Up to 10 hours of battery life
The replaceable standard 18650 battery provides up to 10 hours of operation and allows for easily sourced spares to extend observation sessions.
Simple and intuitive interface
The interface uses clear icons and a simplified layout to make the monocular easy to operate regardless of language and to reduce the time needed to access each function.
Wi-Fi connection and TargetIR usage
The Wi-Fi connection allows you to link the monocular with the TargetIR app to share thermal images in real-time from a compatible phone.
OTA firmware updates
The connection to TargetIR allows for wireless firmware updates to keep the device's functions and improvements up to date.
