  • Operating Temp.: -13F to 122F

  • Water Resistance Level: IPX-7


The device is built with rugged, lightweight, and quality materials to provide strength.

And this material consists of the IPX-7 rated water-resistant aspect to protect the device from worse damages caused by the weather.

By the water-resistant characteristic fo the monocular, it can be acted as the submersible thermal monocular in 3 ft. of water for up to 30 min.

Thermal Sensor

The Helion 2 XQ38 is configured with a high-quality thermal core sensor with a resolution of 384×288 pixels. This thermal sensor has a pixel size of 17 microns.

Like other thermal monoculars from the Helion series, the Helion 2 XQ38 is equipped with a 50Hz of refresh rate.

With this proper and high refresh rate, you can comfortably view the object even in dynamic or rapid motion.

There is a qualified stadiametric rangefinder comes with the monocular unit. You can be detecting the object with the aid of accurate distance given by the rangefinder reticle which is actually fitted with estimated heights of observed objects.

This estimated object distance is very reliable, repeatable, and easy.

Optical System

With the aid of QD germanium lenses, you can easily adjust the focal length to 32mm while detecting the target in both night and day time.

But you can’t swap or remove the lenses which are the disappointment of this lens system. To view the object closer the device is designed with the magnification range from 3.5X to 14 x.

When it comes to thermal monocular, the magnification range is one of the important features to consider.

This Pulsar Helion 2 XQ38 Thermal Monocular has the variable magnification, the magnification range of this monocular is from 3.5x to 14x; due to this range, you can easily detect the object up to 1475 yards.

The optical lens of this thermal monocular has 3.1x magnification, and the digital zooming is 4x, it will help you to see the zooming image of the target.

Due to this magnification range, you can get a crisp and clear view of the long-distance target.

The magnification range is the only difference between the Helion 2 XQ38 and Helion XQ38F monocular from Pulsar.

The magnification range of the Helion XQ38F monocular is 3.1-12.4x; due to this magnification range, the minimum focus distance is 3 m.

The detection range of this thermal monocular is 1475 yards.

The magnification is not a big deal for these thermal monoculars, because the detection range is the same for these both thermal monoculars.

Both the Helion 2 XQ38 and Helion XQ38F Thermal Monocular from Pulsar are the best choice for the outdoor use.

Integrated Gyroscope & Accelerometer

An integrated accelerometer enhances the accuracy of the viewing and it gives the appropriate detecting angles which are greater than 5°, thus you can’t miss your target.

On the other hand, the monocular comes with a built-in gyroscope that fitted with an arrow for indicates the degree of sideways tilting and direction of the target.

If there are any increased angles, that are denoted by the supplemental arrows.

There is possible to disable the operation of the unit when the horizontal angle is higher than 30° or the vertical angle is higher than 70°.

The important thing about the accelerometer is that it will be disabled if it used at excessive angles continuously.

PIP Mode

It comes with the PIP (Picture-in-Picture) mode, it allows you to receive the wide field of view when you zoomed-in the image and gives you a narrow range field of view while you zoomed-out the image.

The sight picture simultaneously shows both the zoomed-in and zoomed-out images.

Pulsar Helion series is the first-ever thermal monocular produced this kind of innovative image enhancement.

This PIP window includes 1/10 of the device’s display to the FOV, and this delivers unobstructed PIP & entire FOV viewing simultaneously in its remaining portions.

Image Process

The high sensitive thermal images are captured in the optical temperature ranging from -13 to 122 Fahrenheit.

And those images are highlighted by the appropriate color which depends on the color palette you choose.

Images show the hot/cold peripheral conditions are varied by the 8 robust thermal imaging color palettes.

With the highly sensitive detector, you can view the target at a distance of 1475 yards.
