The Burris Thermal Handheld H35 Gen 2 400x300 12µm (BTH35 v2) is a high-performance thermal imaging handheld monocular designed for nocturnal observation, tracking, and scanning. Featuring a 400x300 VOx thermal sensor with a highly sensitive 12µm pixel pitch and a 50Hz refresh rate, this unit provides smooth, detailed thermal rendering on a high-resolution 1280x960 LCOS color screen. Equipped with a premium 35mm F1.0 manual-focus objective lens, it delivers a 7.8°x5.9° field of view optimised for mid-to-long distance target identification, offering a variable magnification range from 3.3x to 13.2x.

Key Features

• Long-Range Detection: Features a maximum overall target detection range of up to 1,000 meters, with automatic hot tracking software designed to highlight and track the hottest heat signature on screen past 750 yards (approximately 685 meters).
• Advanced Targeting Tools: Built-in stadiametric ranging software allows users to estimate distance based on target height profiles, supported by five selectability color palettes (White Hot, Black Hot, Red Hot, Green Hot, and Blue Hot).
• Ruggedised Housing: Holds an IP67 dustproof and waterproof rating, enabling the unit to withstand rain, dust, and brief submersion in water up to 1 meter for 30 minutes.
• Smart Connectivity: Integrates internal Wi-Fi to stream real-time video, capture photos, and access remote control functions using the BurrisConnect mobile application.
• Efficient Power System: Powered by an internal rechargeable lithium battery providing 5 hours or more of continuous operation (measured at 25°C) via a standard USB-C charging port.

Who is the Thermal Handheld H35 Gen 2 400x300 12um for?

• Professional pest control hunters — rely on the 1,000 meters maximum overall target detection range of this thermal imaging handheld monocular to locate and identify feral animals across wide open fields before planning an approach.
• Search and rescue personnel — require a lightweight, highly portable device that weighs only 620 grams to track human heat signatures during demanding, long-duration foot patrols in difficult terrain.
• Wildlife management officers — utilise the high-contrast 400x300 VOx thermal sensor to conduct detailed nocturnal population surveys of native and invasive fauna without introducing disruptive visible light.

Less suitable for: shooters requiring a weapon-mounted thermal optic; because this handheld monocular has no recoil rating and cannot be mounted directly to a firearm, a dedicated recoil-proof weapon-mounted thermal scope is required for shooting applications.
