Thermal imaging is fast becoming part of most people’s daily life.
For a common person, thermal imager would be just a toy; but an individual who understands the feature and specification of the device can get a lot of benefits out of it.
While Leupold is a legendary brand in the optics industry, its thermal imaging products are also gaining popularity over the years.

then we’ll further review Leupold LTO Quest vs SEEK thermal imagers as alternatives.
Leupold LTO Quest vs Tracker HD: The Differences?
Let’s start with Leupold Quest, a handheld thermal camera with rugged rubberized body.
It can detect heat signature within temperature range of -40F to 872F both at night and during the day, and display the thermal images on its 2.4″ LED screen.
The base model is equipped with 206 x 156 thermal sensor and 15 Hz frame rate, whilst this thermal camera with fixed focus has heat detection distance of 300 Yards (900 ft).
Its 8 different color palettes can be utilized to suit every environment. You can change the color of the images to green, white, black, red, copper, etc.
Most people find Leupold LTO Quest is good enough for their home improvement and basic hunting / scouting needs, as you can see from these >> user reviews and feedback.
With the control buttons at the front middle section, this is a single-hand operated thermal device that is easy to use.
Its entire IPX-7 waterproofing body is sealed using a rubber cover, with the roughness of the rubber cover is also helpful to increase grip during the action and especially when it is raining.
If needs arise, you can utilize its built-in 300-lumen flashlight. This is a handy feature that can be used to light up your path during hunting and tracking downed game, while it can also be used for home improvement projects on hard-to-reach areas.
But of course, you can detect any heat-emitting object at night with thermal imager – without using the flashlight. This can help you to remain anonymous in darkness.
Watch the excellent video below to get detailed overview on Leupold LTO Quest HD version with two higher configurations –
i.e. 320 x 240 thermal sensor and heat detection distance of over 400 Yards (1200 ft) :
On the other hand, Leupold LTO Tracker HD is a thermal Scope, or thermal Monocular.
Many hunters love to invest in thermal scope/monocular, as this hunting gear can help to look through the bushes, scout animals in the woods, get a clear view of target in darkness before triggering a clear shot from distance, track blood trail, etc.
And Leupold LTO Tracker is among the 2 cheapest thermal imaging monoculars that you can find in the market, which is why it becomes a popular choice for those looking for an entry level thermal scope.
Equipped with 320 x 240 thermal sensor and high resolution 390 x 390 display, LTO Tracker HD offers an impressive long heat detection distance of 750 yards (2250 ft) – according to the product specification.
This thermal device with gorilla glass display is built out of aluminum housing, thus gives a solid and tough feel; Scopecoat and lens cover are also included.
The base model of Leupold LTO Tracker 2 has 10 hours battery life, vs 3 hours bettery life of the Leupold LTO Tracker 2 HD thermal viewer which consumes more power.
Thermal imaging scope is also great for law enforcement, security, surveillance, and various casual use in daily life.
A thermal imager has the ability to detect heat signals and infrared radiation that are emitted from the objects, then creates a thermogram that is represented by various colors, with each color represents a specific temperature.
By default, bright colors (such as red, orange, yellow) indicate warmer temperatures, while dark colors (such as black, purple, dark blue) indicate cooler temperatures.
For instance, you can use the versatile Leupold LTO Tracker HD thermal viewer with night version to explore the neighbourhood, detect suspicious behavior or objects in dark scenes around your house or public car park, locate your pet, and much more.
This HD thermal scope also includes key features like 7x digital zoom and 6 color palettes.
