Purpose of the Thermal Imager Pulsar Helion 2 XP50 PRO

The Pulsar Helion 2 XP50 PRO thermal imager is an observation device that can be used in any light conditions, including complete darkness, in conditions of precipitation, fog, smog, sandstorms, and smoke screens.

Shrubs and foliage, under certain conditions, although they hide the object of observation, leave opportunities for its detection by a thermal imaging device. The thermal imager is designed for civilian use; it can be useful for rescue and law enforcement services, travelers and hunters.

From My Point of View, Only a Few Features Need Comments:

1. Viewing Modes: The thermal imager has three viewing modes with preset brightness and contrast settings. Depending on environmental parameters such as humidity, air temperature and landscape, different brightness and contrast values ​​of the thermal imager allow you to better see the details of the thermal image.

The fourth mode is custom: in it, you can save your brightness and contrast values, which have the best effect on the rendering of the image for the current weather conditions.

 2. Image Detail Boost Technology is based on a combination of proprietary image processing algorithms that improve image clarity and enhance overall image detail. The application of “Image Boost” makes the picture sharper and more detailed, allowing you to increase the ability to identify objects.

Differences from the previous top Helion model: lens, sensor, display. Everything has become better and more modern.

The resolution of the new sensor is 640 * 480 with a pixel size of 17 microns; the material from which the sensor is made is amorphous silicon (a-Si), a parameter that characterizes the sensitivity of the NETD sensor is less than 25 mK, and the previous Pulsar Helion model without the PRO prefix had a NETD value less 40 mK, the difference in sensitivity is almost twice. Let me remind you that the smaller the NET, the more sensitive the thermal imaging sensor is.

The lens of the new PRO model is faster than the previous model; it has the same focal length of 50 mm, but the relative aperture is now 1.0 versus 1.2 for the old model, and the physical lens size is 50 mm versus 42 mm for the previous Helion2 XP50.

The eyepiece unit has also become better: the resolution of the new HD AMOLED microdisplay in the PRO model is now 1024*768 pixels, and it was 640*480.


The appearance has changed compared to the previous model of the thermal imager. Firstly, the lens stands out, has become larger, and is noticeable. Secondly, it is the body and body material.

Outwardly, the Helion 2 XP50 resembles a spaceship: the monocular is made in the style of modern high-tech using a high-strength and lightweight magnesium alloy. The weight of the thermal imager is 500 grams, dimensions in millimeters are 242*75*60.

Operating Time and Power Supply

Helion series thermal imagers use their B-Pack power supply system. Its essence is the use of quick-change battery packs of various capacities of our own design. The Pulsar Helion 2 XP50 PRO is equipped with an IPS7 battery with a capacity of 6.4 ampere-hours.

The operating time from this type of battery pack is approximately 8 hours. When using the IPS14 block, the operating time is more than 12 hours. The battery packs can be changed in a few seconds.


Thermal imager Pulsar Helion controls the body of the thermal imager.

Controlling the thermal imager Pulsar Helion 2 XP50 PRO is simple and intuitive. To use the device, it is enough to know the location of just one “on” button, and turning on the device, you need to rotate the ring at the eyepiece to make the diopter adjustment so that the numbers are on the screen become clear.

This is done once and allows you to focus on the object of observation (by rotating the lens setting).

This is minimal enough. You may no longer need any other Pulsar Helion buttons. However, they are there, but interacting with the device is very simple, so you probably don’t even have to open the instructions.

Positioning of Pulsar Helion 2 XP50 PRO

Pulsar produces several thermal imaging devices for observation: Pulsar Axion compact thermal imagers, Pulsar Accolade LRF XP50 PRO premium thermal imaging binoculars, Pulsar Helion line of thermal imaging monoculars, in which the Pulsar Helion 2 XP50 PRO model is the most advanced of all Pulsar monoculars.

It is no exaggeration to say that the Pulsar Helion 2 XP50 PRO is a premium product with the fastest lens and the most sensitive sensor of all thermal imagers. Therefore, if you are looking for the best surveillance device, this is the Pulsar Helion 2 XP50 PRO series.


There are many emotions, and all are positive:

  • The device is a “bomb.”
  • Its picture is magnificent.
  • Its appearance and ergonomics are beyond praise.

The Pulsar Helion 2 XP50 PRO is the top rated thermal imaging monocular in the global thermal imaging market. None of the competitors come close to this thermal imager regarding image quality or service capabilities.

The changes in the PRO version are significant: The new sensor and the new lens are worth it to upgrade to the PRO version from the previous version of the Pulsar Helion. Additionally, the PRO version offers enhanced features and improved performance.
