Guide KODIAK TK635L 3.0

• 640x512 thermal sensor with 15 mK NETD: The high-resolution 12.00 μm VOx sensor picks up very small temperature differences, helping the monocular separate animals, people and background detail more clearly in difficult weather and low-contrast night conditions.
• Integrated 1200.00 m laser rangefinder: Built-in distance measurement removes the need for a separate handheld rangefinder, making it easier to judge distance quickly while stalking, scanning fields or observing from a fixed position.
• 35.00 mm F 0.9 objective lens: This lens balances a wide viewing angle with strong thermal light intake, giving the user a broad search image while still maintaining useful detection performance out to 1800.00 m.
• 2560x2560 AMOLED display: The high-resolution AMOLED screen presents thermal detail and on-screen data with strong contrast, which reduces eye strain during longer observation sessions and makes fine target features easier to read.
• Compact dual-battery design: At 524.00 g and 182.00 mm long, the KODIAK TK635L 3.0 stays portable for one-handed use, while the dual-battery system supports 5.50 h of operation for longer time in the field.

About the Guide KODIAK Series

The Guide KODIAK series is a family of handheld thermal imaging monoculars with integrated laser rangefinders, developed for users who need one device for observation, detection and distance measurement. In Guide’s outdoor lineup, the series sits as a compact but highly capable option for night hunting, wildlife observation, search tasks and general field use where fast target location matters as much as image clarity.

A defining characteristic of the series is its focus on combining a high-sensitivity thermal sensor with a practical field shape that is easy to carry and quick to deploy. The KODIAK models use a 640x512 VOx sensor with 12.00 μm pixel pitch and 50.00 Hz refresh rate, paired with a high-resolution AMOLED display for smooth viewing and clear image presentation. The built-in laser rangefinder adds a major practical advantage for users who need to confirm distance without switching devices. Across the series, the design philosophy emphasizes compact dimensions, dependable weather resistance, onboard photo and video recording, and wireless connectivity, making the KODIAK range well suited to users who want thermal imaging performance in a portable observation tool.

About the Guide KODIAK TK635L 3.0

The Guide KODIAK TK635L 3.0 is the wider-view model in the series, built around a 35.00 mm F 0.9 objective lens and a 12.50 ° field of view. That combination makes it especially useful for scanning woodland edges, fields, tracks and mixed terrain where covering ground quickly is more important than using a narrower, long-focus image. Its 2.80 x to 22.40 x magnification range gives the user a practical base image for searching, with additional zoom available when checking heat signatures more closely.

The thermal core uses a 640x512 VOx uncooled sensor with 15.00 mK NETD and 12.00 μm pixel pitch. In practice, this means better separation between target and background when temperature differences are small, such as damp mornings, light rain or cluttered terrain. The 50.00 Hz refresh rate helps the image stay fluid while panning, which is important when following moving animals or scanning from a vehicle or hide. Detection range reaches 1800.00 m, giving the TK635L 3.0 enough reach for early spotting before moving closer for identification.

The integrated 1200.00 m laser rangefinder adds real field value by allowing distance checks directly through the monocular’s internal display. The 2560x2560 AMOLED display supports detailed image viewing, while photo and video recording let the user document observations. Bluetooth, USB and WiFi expand connectivity options, and the dual-battery design supports 5.50 h of operation. With its 524.00 g weight, compact housing and waterproof, fogproof construction, this thermal monocular is well suited to mobile use in demanding outdoor conditions.

About Guide

Guide Infrared was established in 1999 in Wuhan, China. The company focuses on infrared imaging technology, and its outdoor portfolio includes handheld thermal monoculars and thermal imaging attachments intended for night hunting and related field use. Guide’s thermal products are also used in areas such as search and rescue and law enforcement, reflecting a broader specialization in practical infrared observation tools.

The company’s product development is closely tied to its own thermal technology base. Guide Sensmart, a wholly owned subsidiary of Guide Infrared Group, develops infrared thermal imaging products using self-developed infrared cores. In 2024, Guide Sensmart established the Guide Outdoor sub-brand for thermal imaging and night vision optics. This background is relevant to the KODIAK series because it places the monocular within a manufacturer that builds its own thermal imaging ecosystem rather than treating outdoor optics as a side category.
