The Leupold LTO Tracker HD Thermal Viewer is the next generation of thermal imaging technology. It combines a high-definition (HD) thermal imager with a state-of-the-art optical system to deliver an unmatched view of the world in all light conditions.

The Leupold Tracker delivers clear thermal images with increased temperature sensitivity. The 206×156 thermal sensor can easily pick up heat signatures 800 yards away, enough to spot the game in the dark. The display automatically adjusts brightness and contrast for optimal detail in any lighting condition, including total darkness. The LTO also has pitch stabilization and a digital elevation readout for accurate distance measurements. Because of how light and small it is, you can easily slip it into your pocket. So, it’s great for wildlife enthusiasts. The battery dies quickly, but you can use a battery bank to charge it on the go.

This is a comprehensive Leupold LTO Tracker HD Ther review. This review will discuss its features, specs, and available sizes in detail. 



The LTO Tracker HD Thermal Viewer weighs 5.6 ounces with the battery installed, which is about average for a handheld infrared camera. However, it’s slightly heavier than other models on the market (for example, the FLIR T420 weighs just 4.8 ounces). As sizes are compact and lightweight, you can conveniently take them anywhere you like. You can conveniently use them to track games and blood trails during the day or even at night. 

Viewing screen

The viewer’s high-resolution OLED display is as sharp and clear as you’d expect from Leupold optics. It’s easy to read in any light condition, and the viewing area is large enough to see detail clearly. There are no controls on the viewer itself; all adjustments are made on the app.

Night Vision

The LTO Tracker HD has night-vision capability, an excellent feature for hunters who like to hunt at night. When you activate night vision, the screen will turn greenish black, making it easier to see through tree cover at night than white light.

GPS Tracking

You can also use this unit as a GPS tracking device by connecting it to your phone’s GPS receiver via Bluetooth LE (Bluetooth 4). This will allow you to track where your shots landed after each photo taken with this device.

Temperature range

The temperature range for the LTO Tracker HD Thermal Viewer is -4 degrees to 122 degrees Fahrenheit.

Thermal sensor temperature

If the thermal sensor temperature is too high or too low, the unit will display a warning message, and the user will be prompted to adjust the thermal sensor. To avoid this issue, ensure that you are not wearing gloves when operating the LTO Tracker HD. Gloves can impede heat transfer from your hand to the device, causing an inaccurate reading of your body’s core temperature.


Battery Life:

Battery life is an important consideration when purchasing a thermal viewer. You want to be able to use it for extended periods without having to recharge. The Leupold LTO Tracker HD features a battery life of up to 8 hours, significantly longer than the average of 2-3 hours for most other models.

Display size

The display size is another important factor when choosing a thermal viewer. This number indicates the size of the screen, and it will determine how much detail you can see through the device. The Leupold LTO Tracker HD has a display size of 3 inches, which is on par with the average for this type of product. However, it does feature a larger viewing area than most other products today.

Field of view

The LTO Tracker HD has a clear field of view without distortion or blurriness. You can easily see animals 100 yards away, and the camera will allow you to focus on objects as close as 30 feet. The unit comes with two different types of screens: a monochrome screen and a thermal screen. The monochrome screen is used in daylight conditions, while the thermal screen is used at night or in low light situations. Both screens show the same image, but each is optimized for its respective environment.


The LTO Tracker HD has a magnification of 1x to 6x, which means that when you look through it, everything appears to be closer than it is. This can be useful in some cases but makes it much harder to shoot accurately at long ranges.

Eye Relief

Eye relief refers to how far away from your eye the scope needs to be so that you don’t get poked by your gun’s muzzle when shooting. The LTO Tracker HD provides a generous 15mm of eye relief on its highest magnification setting, meaning there is plenty of room between the scope and your face when you’re shooting with it mounted on your rifle.

Gorilla Glass Display Cover

Gorilla Glass covers offer superior screen protection against impacts and scratches.
