Leupold LTO Tracker 2 Thermal Monocular Review (2022)

leupold lto tracker monocular

This is a comprehensive Leupold LTO Tracker review!

This thermal monocular can display heat signatures of your game from 600 yards no matter what time of day or night you are hunting. Its lightweight and compact construction allow you to carry it in 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.

In this review, we will discuss its features, specs, and available sizes in great detail. 

Leupold LTO 2 Tracker Overview

Before we begin with the analysis, you need to know that the manufacturer has discontinued both Leupold LTO 2 and LTO 2 HD models. But you shouldn’t be worried because you can still buy these from different online stores. If this is a turn-off for you, you can check our alternatives lists right at the end of this review. 

The Leupold Tracker delivers clear thermal images with increased temperature sensitivity. Due to the 206×156 thermal sensor, it can easily pick up heat signatures 600 yards away, which is enough to spot the game in the dark.

The Leupold LTO is for hunters and wildlife enthusiasts who like to follow tracks for observational purposes. You can also use it for surveillance and spot the intruders without alerting them in the dark.

Leupold LTO 2 Tracker monocular is made in Beaverton, Oregon, like the rest of the brand’s stuff. So, you’ll get an uncompromisable viewing quality made in the USA. The price is justified when we look at the features of this thermal monocular. 

There are two sizes available in Leupold Thermal Tracker, and they are good enough to serve the purpose here. 

We will be focusing our review on the LTO Tracker 2 monocular because the HD version is three times more expensive. The following two sections will describe some features that are common in both sizes with a brief comparison. But in the later sections, we will cover individual features of both sizes.

Leupold LTO 2 vs. LTO 2 HD

Both the Leupold thermal monocular sizes are compact and lightweight, and you can conveniently take them anywhere you like. You can conveniently use them to track games and blood trails in the day or even at night.

Tracker 2’s detection range is up to 600 yards, which is good if you’re using it for hunting, surveillance, or detecting a raccoon in the attic. On the other hand, LTO 2 HD is more powerful and comes with a detection range of 700 yards. You can use the extended range for finding a lost hiker at night. 

Due to extra power, the LTO 2 HD consumes the battery faster. The LTO Tracker 2 monocular can last for up to 10 hours per charge, while the HD size can only last for 3.

It means you cannot take the LTO Tracker 2 as far in the backcountry as the LTO 2. You can take a battery bank with you to recharge the device on the go. The HD model also comes with a lens and eyepiece caps.

Optical performance

This LTO Tracker 2 thermal monocular’s overall optical performance is great. It’s so precise that you can differentiate a raccoon from a bear without alerting them from a distance of 600 yards. You can use it both during the day and nighttime with clear thermal images.

This Leupold LTO thermal imager comes with a 1.2-inch round AMOLED display that can deliver full-screen thermal images with clarity in 240×204 resolution.

A high resolution would produce better results but this resolution is still good enough to track the game in the dark. The details are sharp, and you can conveniently find any heat signatures or blood trails in any terrain.

With just a push of a button, two boxes appear on the screen to spot the hottest and the coolest spots on the screen, one in red and one in blue.

It also features a dimmable display to adjust the brightness according to the light conditioning in your surroundings. It means you can conveniently adjust the brightness of the screen during a hunt in the nighttime to spot your game.

Thermal quality

Leupold LTO 2 monocular provides you better results with higher temperature sensitivity no matter how dark it is. It works fantastic to count bats in a cave where your flashlights could fade away.

The infrared thermal technology performs well in mines, caves, or tunnels with zero light. With its 240×204 display, you can see the walls in the pitch dark. This is not going to be that big, but it certainly gets the jobs done to detect the heat signatures or see down-tube in underground caves. 

The Thermal Tracker monocular comes with a frame rate of 30 Hz, so you will not miss any details, even for a moving target. 

If you are looking to use this thermal tracker to explore the outdoors, or just have fun with it, then 9Hz is all you need. However, when it comes to hunting or contract shooting 30Hz or higher is recommended.

User interface

The overall user interface of this Leupold thermal scope is relatively easy on the eye. And all necessary details are available at a glance. There are six different color palettes to choose from based on the surrounding conditions to minimize eye strain, which is better than a Leupold night vision scope.

The monocular comes with a Beacon Mode, which can quickly calibrate your screen for better detection in warmer environments. This feature is not there in any Leupold night vision device.

You will get a grayscale screen under this mode with the Beacon threshold. And as soon as a warmer spot is detected, it will be displayed in Hi-Bright conditions. A small red box on the screen will help you identify the warmest part of the landscape.

Body and grip

Leupold LTO 2 Tracker comes with a very compact design. You can easily carry it in your pocket. Leupold has used lightweight but durable aluminum to construct this monocular. It gives ruggedness and durability, irrespective of the terrain impact. 

This Leupold thermal viewer can handle moisture and fog quite well due to the mist and waterproof technology that Leupold has used with advanced gassing and sealing techniques. 

This Leupold thermal optic can withstand harsh environments and extreme temperatures and continue to show you thermal images for a long time. 

Additional functionalities

This monocular comes with manual gain control in the Hi color palettes. This adjustment allows you to tweak the brightness according to the current light conditions to focus the washed-out objects in the darkness.

You can magnify the image 7x for more details and a cleaner shot. You can use the digital zoom from the center button and cycles up from 1.0, 1.7x, 3x, 5x, and 7x. The thermal sensor is fixed at 76,800 pixels, so the image doesn’t fall apart until 3x.

It also features a powerful CR123 battery that can last up to 10 hours or for the entire day. 

Leupold LTO Tracker model sizes

There are two sizes available, and the most popular one is the LTO-Tracker 2 for its better battery life and lesser price. 

The following table will provide you with a detailed overview of both the sizes available in this model.

Leupold LTO-Tracker 2 Thermal monocular 

After the Leupold LTO Tracker 2 review, I found it more useful than the HD model because there’s not much difference between the features. This monocular has a detection range of up to 600 yards. It can conveniently detect a deer at 250 yards and provide you crisp images in any condition. 

You can also magnify your target up to 7x for more details, and with 14 degrees of angular FoV, you can better assess your target’s surroundings. 

The Leupold LTO-Tracker 2 Thermal Imaging Monocular is better suited for more extended sessions because it has a lightweight body. It also comes with a CR123 battery that will last for up to 10 hours. 

So, you won’t have to keep charging it after a short while. The Leupold LTO Tracker is a great choice for hunters on the go who are looking for more precision to up the ante. 

Leupold LTO-Tracker 2 HD Thermal monocular

According to my Leupold LTO tracker HD review, I would say it packs quite a punch. The Leupold LTO Tracker HD comes with a powerful thermal sensor. It will provide you some sharp details about your game and its surroundings. 

If you are an ambush hunter and don’t like to move around too much during your hunt, this device suits you well. It will also work great for surveillance and finding a lost hiker; because the Leupold LTO Tracker 2 HD provides exceptional sharpness in dark pitch conditions. 

However, the Leupold LTO-Tracker 2 HD Thermal Imaging Monocular doesn’t come with great battery life and can only last for up to 3 hours on a full charge. Now, that can be a significant disadvantage if you are chasing your game. 

Leupold Warranty

Leupold stands behind its products and provides its customers with a lifetime warranty, and you don’t need to have proof of ownership and no time limit whatsoever. Leupold also provides a 2-year warranty on all the electronics involved in its products. 

This warranty covers any issues associated with the materials or craftsmanship of the products. Still, it excludes loss, theft, or any cosmetic alteration or damage to the device that is halting its performance. 


After the LTO-tracker Leupold review, the only issue I found is that imaging becomes slightly blurry at high magnification (7x). And it will become even more noticeable when the light conditions are not that great. It works best around 3x, but it begins to get blurry after that. 

You can go for the HD size if you are looking for a better result at high magnification. However, low battery life is a problem for HD models. The Beacon mode consumes the battery very quickly so you can turn it off to save the battery. You can also use a battery bank to charge it on the go.  

What’s in the box?

  • Leupold Tracker LTO 2 thermal monocular
  • A carrying case
  • A neck strap
  • Leupold lifetime warranty
  • 2-year warranty on electronics

Considering that it’s a thermal monocular, Leupold could have slipped in an eyepiece cap and a lens cap that only comes with LTO-Tracker 2 HD size. Therefore, you will have to buy them separately. The rest is all fine here!

Leupold LTO Tracker user reviews

Leupold LTO Tracker 2 comes with a user rating of 4.0, which is not that bad at all. 

The users have complained about this monocular price tag but nothing about the overall performance in the field. Some people have also mentioned the fact that these monoculars do get blurry with increased magnification. 

But a vast majority has complimented it for its excellent low light performance and different color palettes to take care of that eye strain.


From OpticsPlanet


Since the manufacturer has discontinued them, I have some alternatives for you to choose from. 

FLIR Systems Scout III

With a thermal resolution of 640×320 and an angular FoV of 18 degrees, this thermal night vision monocular is extremely powerful and is built for serious hunters and surveillance purposes. It can detect heat signatures up to 1247 yards away and comes with full water and fog-proof construction. 

FLIR Systems Scout TK Mini Thermal Monocular

If you are looking for a budget-friendly option, consider Scout TK the right option. With a display resolution of 640×480, this device can produce sharp images and ensure a wide angular FoV. This device comes with a detection range of 100 yards. 

Pulsar Axion Key XM30

Here’s another thermal monocular that also comes with a rangefinder. It can manage a resolution of 960×720 and can provide you with exceptional image details. It comes with an angular FoV of 7.3 degrees and an eye relief of 14mm. 

Our verdict

Overall, I think the Leupold Tracker LTO 2 thermal monocular is quite a good option for anyone who likes to hunt during the night. It can detect thermal signatures from a distance and comes with different color palettes to ease the eye strain in different light conditions. 

Its battery lasts for an entire day pretty comfortably. The most popular size is the LTO 2 because of its lesser price and better battery timing for the hunters on the go. 

As Leupold has discontinued this product, you cannot buy it from the manufacturer directly. However, you can purchase it both in-store and online from authorized dealers and retailers.

1 thought on “Leupold LTO Tracker 2 Thermal Monocular Review (2022)”

  1. Why discontinue a product described as promising? If they guarantee the product are there downsides to purchasing? I have used Leupold products in my work and am impressed with Leupold’s first foray into the I.R. World. The consensus of opinion, if the above is true, is to make the purchase.
