Guide TE419S Thermal Monocular

The Guide TE419S Thermal Monocular combines a high-sensitivity 400×300 thermal sensor with a compact handheld design, providing a wide field of view and capable thermal detection in a lightweight package.

Featuring a 400×300 12μm thermal detector with 15mK NETD thermal sensitivity, the TE419S is paired with a 19mm objective lens and provides a detection range of up to 1000 metres. Its relatively low 1.4× base magnification and wide field of view make it particularly well suited to scanning terrain and locating heat signatures across a broad area.

Guide's ApexVision S1 image processing system enhances thermal image clarity and detail, while an 800×600 AMOLED display, 50Hz refresh rate and multiple thermal palettes provide a smooth and adaptable viewing experience.

At just 288g, with video and audio recording, Wi-Fi connectivity, USB-C fast charging and IP67 protection, the TE419S is a versatile thermal monocular for hunting, wildlife observation, property monitoring and outdoor use.

ApexVision S1 Image Processing

The TE419S incorporates Guide's ApexVision S1 image processing architecture, designed to enhance thermal image clarity, detail and overall viewing performance.

Advanced image processing works alongside the high-sensitivity thermal detector to improve image definition and provide smooth thermal imagery across varying field conditions.

This helps users distinguish heat signatures and surrounding terrain when environmental conditions reduce natural thermal contrast.

400×300 12μm Thermal Sensor

At the heart of the Guide TE419S is a 400×300 thermal detector with a 12μm pixel pitch.

Combined with 15mK NETD thermal sensitivity, the sensor is capable of detecting subtle differences in temperature within a scene, helping produce detailed thermal images in challenging conditions.

A 50Hz frame rate provides smooth imagery while scanning terrain or following moving subjects.

19mm Lens & 1000m Detection Range

The TE419S features a 19mm objective lens, providing a useful balance between detection capability and a wide viewing area.

With a stated detection range of up to 1000 metres, the TE419S provides capable observation across open terrain while retaining a relatively low 1.4× base magnification for easier scanning.

Magnification can be increased up to 5.6× when a closer look at a detected heat signature is required.

Wide Field of View

One of the TE419S's key advantages is its broad 14.4° × 10.8° field of view, equivalent to approximately 25 × 19 metres at 100 metres.

The wider viewing area allows more terrain to be observed at once, making it easier to scan paddocks, bushland and other outdoor environments for heat signatures.

This makes the TE419S particularly suitable for users who prioritise scanning capability alongside longer-range thermal detection.

Simple One-Button Control

The TE Series features Guide's streamlined one-button and control-ring interface, keeping operation straightforward and reducing unnecessary controls.

Commonly used functions and menu settings can be accessed through the simplified interface, helping make the monocular easy to operate while moving or observing in the field.

Compact 288g Design

Measuring approximately 47 × 47 × 148mm and weighing only 288g, the TE419S delivers 400×300 thermal performance in a compact handheld format.

Its relatively small dimensions make it easy to carry in a pocket, pack or equipment pouch and keep accessible during extended periods outdoors.

800×600 AMOLED Display

The Guide TE419S features a 0.32-inch 800×600 AMOLED display, providing a clear and detailed view of the thermal image.

Multiple thermal colour palettes are available, including White Hot, Black Hot, Red Hot, Green Hot, Iron Red, Blue Hot and Sepia, allowing users to adjust the image presentation for different environments and personal preferences.

A -5 to +5 diopter adjustment allows the eyepiece to be fine-tuned to suit the individual user.

Video, Audio & Wi-Fi Connectivity

The TE419S supports video and audio recording, allowing thermal observations to be captured directly through the monocular.

Built-in Wi-Fi hotspot functionality provides wireless connectivity with compatible external devices for supported viewing, sharing and device functions.

Up to 5 Hours Battery Runtime

A built-in rechargeable battery provides up to 5 hours of operating time.

The TE419S supports USB-C charging and external power, with fast-charging capability allowing a quick top-up when required. A 10-minute fast charge can provide up to approximately one hour of additional operation.

Standby mode also provides a convenient way to manage power consumption between periods of active observation.

IP67 Weather Protection

With an IP67 protection rating, the TE419S is designed for outdoor use where exposure to dust, moisture and changing weather conditions may occur.

Its specified operating temperature range of -20°C to 50°C provides reliable operation across a broad range of environments.
