Leupold LTO Quest Thermal Viewer Review

A Leupold’s LTO-Quest is a robust handheld thermal device with a dual-mode and 300-lumen flashlight with which you can detect heat signatures out to 300 yards. It can make all the difference in tracking downed game or scouting.

Leupold’s LTO-Quest thermal viewer can detect operating temperatures from -4F to 140F. This device startup in less than 3 seconds. The built-in camera takes over 2000 images on a micro SD card slot and has eight color palette options that allow use in any lighting conditions.

The rugged and rubberized body is small enough to fit in your pocket. The LTO quest thermal imager features a 2.4-inch display with a 15Hz refresh rate that provides precise temperature readings of all objects scanned within a 20-degree field of view. It can also use as a valuable tool to measure the heat efficiency of other mechanical devices.

Thermal imagery:

The Leupold LTO Tracker HD comes with a super-sensitive 320×240 infrared sensors. This viewer can identify the object from a distance of 150 yards, and it makes it easy for a hunter because you don’t need to be too close to an animal to take a shot.

Thermal imagery is one method of improving the visibility of things in a dark environment with detecting the infrared radiation. The typical application of this unit is border security. It is mostly used for night vision technologies that can be produced as an image based on that information.

TYPES OF LEUPOLD LTO QUEST THERMAL VIEWER:

There are four types of Leupold’s LTO-Quest thermal viewer available,

1. LTO-Quest
2. LTO-Quest HD
3. LTO-Tracker2
4. LTO-Tracker2 HD

1. LTO-Quest:

It is a thermal viewer and a powerful handheld thermal device.
The LTO-Quest is a dual-mode with a camera and a 300-lumen flashlight. With this device, you can detect heat signatures up to 300 yards, and it makes more difference in scouting or tracking downed game.

2. LTO-Quest HD:

The Leupold Thermal Optic Quest HD thermal viewer is a great handheld thermal tool, a dual-mode, a camera and a 300-lumen power flashlight. This device, you can identify heat signatures up to 300 yards, and it makes more variety in tracking or scouting downed game.

3. LTO-Tracker2:

LTO-Tracker2 is compact, and it shows you the heat signature of game, blood trails, and more—day or night. The LTO-Tracker 2 features new Beacon mode which allows you to quickly recalibrate the screen to improve daytime use.

4. LTO-tracker2HD:

LTO-tracker2 HD features new Beacon mode which allows you to quickly recalibrate the screen to improve daytime use. The Leupold LTO-Tracker 2 HD is the subsequent evolution of thermal, and its objects that come with a similar heat signature to their backgrounds.

Thermal sensor:

The Leupold LTO Tracker HD comes with a super-sensitive 320×240 infrared sensors. This viewer can identify the target from a distance of 150 yards. This makes it easy for you as a hunter because you don’t need to be too close to an animal to take a shot. The thermal sensor comes with the 32-degree field of view, 15-hertz frame rate, 4X zoom, and 750-yard range detection. The temperature sensors most frequently used in thermal instrumentation are thermocouples and platinum resistance thermometers.

There are four commonly used temperature sensor types:

• Negative Temperature Coefficient (NTC) thermistor
• Resistance Temperature Detector (RTD)
• Thermocouple
• Semiconductor-based sensors

Negative Temperature Coefficient (NTC) thermistor:

NTC thermistor is a resistor with a negative temperature coefficient. The NTC sensors are typically used in a range from −55°C to 200°C. It is primarily used as resistive temperature sensors and current-limiting devices. This range is dependent on the base resistance.

Resistance Temperature Detector (RTD):

The RTD is a device that comes with a significant temperature coefficient. It is used as a measurement device. It is passing a low-level current through it and measuring the voltage drop.

Thermocouple:

A Thermocouple is a sensor that is used to measure temperature. The Thermocouple consists of two wire legs produced from various metals. The wire’s legs are welded together at one end, creating a junction. This junction is where the temperature measured. When the intersection experiences a change in temperature, a voltage is generated.

Semiconductor-based sensors:

The semiconductor-based temperature operates with reverse bias; also, it comes with a small capacitance and a minimum level leakage current. It is compact and produces a linear output with a short range of temperatures. It also a low cost and are accurate subsequent calibration.

LEUPOLD LTO TRACKER HD THERMAL VIEWER

The LEUPOLD LTO thermal HD viewer is a second-generation device that can detect heat signatures out to 300 yards. The first impression of the thermal viewer is of a high-quality aluminum flashlight. It is not a rubber eyepiece like on the FLIR scout line that holds the LTO tracker HD out 8-10 inches within your line of sight.

It can produce more of a visible light signature. It comes with an HD 390×390 pixel in a circular display. The LTO-Tracker HD Thermal Viewer displays eight thermal color palettes that allow for optimal thermal viewing in almost any condition. This thermal tracker is small and a high-quality aluminum flashlight, complete with the crenelated bezel.
