Leupold LTO Tracker vs FLIR Scout TK: Any Catch?
If you solely do a side-by-side comparison on the key product specifications of Leupold LTO Tracker vs FLIR Scout TK, it seems a no-brainer that LTO is the obvious winner as it outshines in most aspects.

With Lens Cap
Scout TK thermal monocular, on the other hand, has lens cap and its FLIR proprietary digital detail enhancement for image processing. It is also rated IP67 and submersible.
And if you consider built in video recording function as a mandatory requirement, then Scout TK is apparently the thermal imager you should consider, as LTO does not have this feature.
There are two things you need to know about LTO though, to better align your expectations:
#1: ‘600 Yards’ Detection Distance of LTO Thermal Tracker
The specification of Leupold LTO Tracker indicates it has detection distance of 600 yards.
Watch the Leupold field testing results in this video – are the images at 300 yards clear (without water background)?
Note that the LTO tracker does not have built-in video recording feature, so the images on digital screen were recorded using separate video camera, as such there are certain image resolution loss when we watch these youtube videos – compared to the actual image seen through the thermal monocular screen.
Let’s see another video clip with Leupold field test results, from 50 yards to 300 yards:
If we go a bit more technical into the optical system calculation metrics developed by John Johnson in 1958, below are the definition of Johnson Criterion based on the ability of an observer to detect the criteria 50% of the time:
Detection: Ability to distinguish an object from background
Recognition: Ability to classify the object class (eg. human, animal)
Identification: Ability to describe the object in details (eg. a man with a cap, a hog)
Let’s watch the following “Detection Range of Leupold LTO Tracker” video:
As you can see, the field testing results in videos above show the identification / recognition of the objects in LTO images at 300 yards distance are already below satisfactory, making the ‘600 yards detection range‘ in Leupold LTO Tracker product specification seems somehow a bit suspicious.
#2: Do You Intend To Mount Leupold LTO Tracker To A Rifle?
According to the manufacturer of this handheld Leupold LTO Tracker thermal monocular:
Still, many are interested to mount a Leupold LTO Tracker to a rifle and use it for hunting.
Can you really do that?

Leupold LTO Tracker Reviews: The Verdict
Leupold LTO Tracker thermal viewer is a great deal for those who want to have a cheap affordable thermal monocular for hunting, scouting, and general casual use.

Leupold LTO Tracker or FLIR Scout TK? You decide, based on your preference.
