Description
The Burris BTH35 V2 takes everything that made the original BTH35 a favorite and sharpens it across the board. At its core sits a next-generation 400×300 VOx uncooled sensor with a 12µm pixel pitch, paired with a bright 35mm F1.0 objective. That smaller pixel pitch lets Burris pull strong imaging performance out of a lighter, more compact lens, so you get a crisp, high-contrast picture at a fast 50Hz refresh rate without hauling around a heavy brick. The 1280×960 color LCOS display keeps the view clean whether you're glassing a tree line at dusk or picking apart a field in total darkness.
What the Burris BTH35 V2 Brings to the Field
This is a scanning and tracking tool first and foremost. Hot track technology locks onto heat signatures out past 750 yards, and the smooth 1x to 4x digital zoom (2.3x to 9.2x total magnification) lets you close the distance on something you've spotted without losing your bearings. Five color palettes including white hot, black hot, red hot, green hot, and blue hot give you options for different conditions and personal preference. Stadiametric ranging, adjustable brightness and contrast, plus manual and automatic non-uniformity correction round out the controls so you can dial the image in exactly how you like it.
Connectivity and Handling on the BTH35 V2
Built-in Wi-Fi ties the unit to the BurrisConnect app for real-time video streaming, photo and video capture, and remote control of the device straight from your phone. Burris overhauled the user interface on the V2 with a refreshed menu system and support for multiple languages, and they reworked every touchpoint from the buttons to the focus ring, diopter ring, and eye cups for more natural, glove-friendly operation. It runs roughly 5 hours on its rechargeable lithium-ion power, carries an IP67 weather resistance rating, and weighs in around 22 ounces, light enough to keep clipped to your pack or around your neck on a long night. It's a popular pick with predator hunters, hog guys, and anyone who wants reliable heat detection in a handheld package, and it's backed by Burris warranty support.

Frequently Asked Questions
How far can the Burris BTH35 V2 detect and track heat signatures?
The BTH35 V2 can hot track targets out past 750 yards in complete darkness. Its 400×300 VOx sensor and 35mm F1.0 objective give you enough resolution and light gathering to spot and identify game at those distances. Keep in mind that detection distance is different from clean identification, and conditions like humidity and background temperature will affect how far you can confidently tell what you're looking at.
Does the Burris BTH35 V2 connect to a phone?
Yes. It has built-in Wi-Fi that pairs with the BurrisConnect app, letting you stream live video, capture photos and video, and control device settings remotely from your phone. The V2 got a refreshed user interface and menu system, so navigating those features is more intuitive than on the original BTH35.
What is the battery life on the BTH35 V2 and how does it charge?
The BTH35 V2 runs roughly 5 hours on its rechargeable lithium-ion battery, and it charges over USB-C. Runtime will vary with screen brightness, Wi-Fi use, and temperature. Using the power-saving settings when you're glassing between sightings helps stretch a night out further.
Is the Burris BTH35 V2 a weatherproof handheld or a weapon-mounted scope?
This is a handheld thermal monocular designed for scanning, detection, and tracking, not a dedicated weapon sight. It carries an IP67 weather resistance rating, so rain and dust aren't a problem in the field. At around 22 ounces it's light enough to carry around your neck or stow in a pack during long sits.
