Thermal Vision
Does a thermal imager emit anything and is this radiation dangerous?
Thermal imagers are absolutely safe because the unit itself does not emit anything but only receives and analyses the incoming signal (infrared emission from objects).
Can I use a thermal imager to see through glass?
No, there are no thermal imagers able to look through glass because glass does not let infrared radiation within 8–14 ɥm pass.
Can the bright sunlight damage a thermal imager?
It is not recommended to point the thermal imager with open lens cap at powerful sources of energy (unit emitting laser radiation or the sun), because it may negatively impact the accuracy of the thermal imager.
Do not use your thermal unit at temperatures exceeding +50 °С as high temperatures may damage the unit.
What is the service life of thermal devices?
The notion of “service life” should be treated in an integrated manner (microbolometer, display, boards, buttons, shutter and other parts and assemblies). Component manufacturers may include maximum service life information in the technical specifications.
Yukon Advanced Optics tests all parts and joints for nonfailure operating time before launching series production of its units. Every unit produced by our company is covered by a three-year warranty which includes free warranty service. Adhering to the rules of operation may significantly extend a unit’s life.
Why is the image quality when using the scope at low temperatures worse than at positive temperatures?
Due to various thermal conductivity issues, objects (surrounding environment, background) under observation warm faster at positive temperatures, which enables better temperature contrast and, thus, the quality of the image produced by a thermal imager, will be superior. At low operating temperatures objects under observation (background) normally cool down to roughly equal temperatures, which leads to lower temperature contrast and image quality degradation.
Why does the unit drain batteries when it´s switched off?
Please make sure that the unit is switched off completely: press and hold the ON/OFF button for more than 3 seconds – a countdown will display on the screen.
If the button is held for less than 3 seconds, “Display Off” mode will be activated. In this mode the unit still uses power and the batteries will drain.
Also, please make sure you are using the latest firmware update in your Pulsar device.
Can I use thermal rilfescopes on heavy calibre rifles?
Pulsar riflescopes feature a max. shock resistance of 6000 Joules which allows use on heavy calibers.
Please check this value for your cartridges prior to using.
What is zoom zeroing used for?
The zoom zeroing function helps increase the zeroing accuracy of riflescopes. Zoom zeroing allows the shooter to zero the riflescope on zoom. Increasing magnification of the riflescope by 2x (e.g. 1.6x2=3.2) makes the click value two times smaller (click value for every riflescope can be found in the respective reticle catalog or technical specifications of the unit in the user manual). Respectively increasing the magnification of the unit by 4 makes the click value 4 times smaller.
I hear no sound when playing videos on iOS devices. The microphone is on.
Do I need a permission to travel with my thermal imager to other countries?
Thermal devices are export sensitive if exported outside EU.
Also it might be necessary to apply for import license if you are entering the destination country.
Please contact the customs service of the destination country to find out if any restrictions for the import of thermal devices as a personal belonging apply.
Are the batteries charged or do they need to be charged before first use?
Products are supplied with partially charged batteries.
For better experience, we suggest fully charging the batteries before first use.
Please read the user manual for your device for extra information.
Why does the device body get hot during operation?
There is a radiator in the device body – a metal part on the device body is a radiator designed to remove heat from electronic components of the device, which heating up during the operation of the device provide them with the required operating temperature.
After a shot, a semi-circular flare appears at the bottom of the thermal imaging image.
Possible cause
The gun is equipped with a compensator or silencer that radiates heat when fired.Solution
It is recommended to raise the height of the riflescope to a level at which the flare is not visible. After that, you will need to re-zero the riflescope.Thermal Imaging Riflescopes
What is the difference between Thermion 2 Pro and Thermion 2 LRF PRO?
Both models feature very similar specifications; however Thermion 2 LRF Pro has a laser rangefinder (max. range 800m). For detailed specifications please check out this link
Does the scope feature Image Boost?
Image Boost is not available as a dedicated feature but it’s incorporated in all observation modes.
The riflescope is not measuring distance correctly.
Please take note of the following:
- Accuracy of measurement and maximum range depend on the reflection ratio of the target surface, the angle at which the emitting beam falls on the target surface and environmental conditions. Reflectivity is also affected by surface texture, color, size and the shape of the target. A shiny or brightly colored surface is normally more reflective than a dark surface.
- Measuring range to a small sized target is more difficult than to a large target. Accuracy of the measurement can also be affected by light conditions, fog, haze, rain, snow etc. Ranging performance can degrade in bright conditions or when ranging towards the sun.
- When measuring range to a small-sized target located more that 400 meters away, it is recommended that you put your elbow against a solid surface. This is due to possible hand tremors and difficulty hitting the target with the beam at a longer distance.
The rangefinding reticle and aiming reticle do not match, is it OK?
The rangefinding reticle is set to be always in the centre of the field of view and it's not designed for shooting purposes.
The aiming reticle may not be strictly in the centre of the field of view after the zeroing procedure. This depends on the mount type and if the riflescope is mounted and tightened correctly on a rifle.
Can I restore a previous firmware version in your devices?
No, restoring a previous firmware version is not possible.
Can I use Thermion 2 in the daytime?
Yes, you can use Thermion in any weather conditions (fog, rain, mist etc.), night and day.
What mounting rings would you recommend for the Thermion 2?
You can use all types of 30 mm compatible rings and mounts.
There are no special recommendations – the rings should be good quality and sit as low as possible to facilicate zeroing.
You may also consider Innomount – this company produces mounts specially for our riflescopes. Here is a catalog link.
When choosing rings, please take note of the riflescope dimensions.
What would be the recommended torque setting for the mounting rings to install Thermion 2?
The recommended torque setting is up to 2.5 Nm.
My riflescope will not hold zero. What can I do?
Please make sure:
- your riflescope has the latest firmware version. Click here to check.
- you have correctly and firmly installed the riflescope on your rifle.
- you have correctly carried out the zeroing procedure described in the user manual.
My image freezes from time to time. Is this a defect?
In the course of the calibration process the image freezes on the screen – this is normal and not a defect.
Default calibration mode is “Automatic” (the software decides when calibration is necessary) but you can change it to “Manual” mode in the "Main menu" => "Calibration mode" to calibrate the riflescope when you need to based on actual image quality.
lease close the lens cover prior to manual calibration. We recommend using automatic mode all the time.
Please read more about calibration in the user manual for your thermal device.
I can see a ghost image / residual artefacts of the previous image. What is wrong?
You are using the manual calibration mode without closing the lens cover.
Please make sure the lens cover is closed during calibration or switch to the automatic calibration mode if you do not want to close the cover.
I can hear a clicking sound during calibration. Can I turn it off?
No, a clicking sound is normal in the automatic and semiautomatic calibration modes.
You may switch to the manual calibration mode to avoid the sound. Remember to close the lens cover to make sure no ghost images appear on the display.
Why do I need to calibrate the image?
Calibration levels the background temperature of the microbolometer and eliminates image flaws (such as vertical stripes, ghost images of previous objects etc.).
Intervals between calibrations depend on operating time: the longer a thermal imager operates nonstop, the less frequently calibration is required.
There are defective pixels (or pixel clusters) on the screen of my thermal imaging device.
Please note that a certain amount of non-functional pixels (max 0.5% of total quantity) is allowed by the sensor and is not considered a defect. You may try repairing the pixels using the respective menu item of your thermal imager. For details, please refer to the user manual.
Click here to view sample video instructions.
Activate the pixel repair option in the device`s menu. You will be redirected to a window with picture in picture (PiP) mode and an auxiliary cross.
Operate with navigation buttons to move the cross into the bad pixel’s coordinates. Dead pixels disappear when the auxiliary crosss is in the correct position.
Press the ON/OFF button and check for the “OK” message on the display.
Can I power the riflescope from a 12 V car adapter?
Yes, you can use a car adapter featuring a 5V / 2A output.
Can I change the internal battery by myself?
The internal battery can be replaced only at the service center. Please contact your seller or national distributor to arrange return for repair.
Does the riflescope feature Recoil activated video recording?
No, this function is not available. Please use the standard video recording function.
Does the riflescope support a remote control?
No, Thermion does not support a remote control.
To control the riflescope remotely, you may use Stream Vision App available on
Google Play
App Store
Are user zeroing profiles saved when updating riflescope’s firmware?
When updating firmware, user zeroing profiles are saved.
Why is the reticle off the centre after zeroing?
After zeroing the reticle may be slightly off the centre of the field of view which is normal and does not affect accuracy.
If the riflescope is installed properly on your rifle, and the mount is well fixed too, you may not need to move the reticle a lot, thus the reticle will stay very close to the centre.
Does the riflescope save user zeroing profiles if it’s powered down for a long period of time?
Yes, user zeroing profiles are saved even if the battery is not installed in the riflescope for a long period of time.
My image is blurry when I use digital zoom. Is it a defect?
When using digital zoom, image is cropped so resolution will become lower and the image will look not as clear as when using the base (optic magnification).
It's a peculiarity of digital zoom in all devices, and it's not a defect.
Is it possible to upload new reticles to the riflescope?
You cannot do it by yourself. However you can send us a reticle type proposal and we will have it considered.
Can I use my Pulsar riflescopes on a SCAR 17s rifle known for its recoil?
All Pulsar digital and thermal riflescopes feature a max. shock resistance of 6000 Joules.
Please check this value for your cartridges.
Is it safe to use my Thermion on an air/pellet gun?

It's only upgrade (adding the LRF) that is possible.
Please note that a model without the LRF is available - Telos XP50.
What sensor type is used in Telos LRF XP50?
Telos LRF XP50 monoculars use Lynred thermal sensor (France) 640x480 pix. @ 17 µm (NETD <18 mK)
Why is the Telos upgradeable? What does it mean?
Telos is the first line of thermal imaging products on the market with the possibility of technical upgrade at the request of the client. The device provides for the possibility of upgrading components, such as more powerful optics, a sensor or a display with a higher resolution, more efficient and functional electronics, etc.
Can I buy electronic components to upgrade the device by myself?
No, we don’t sell any electronic components or parts.
To upgrade the device, it is necessary to send it to our service center.
Can the Image Detail Boost function work for a long time? Does it damage the device?
Will interchangeable lenses be available for Pulsar Telos XP50 thermal imaging devices?
35 mm and 50 mm are the only lens options we are offering for the Telos. Interchangeable lenses are not currently available separately as accessories or spare parts. All possible changes in the design of devices will be displayed in the Upgradable Device program later.
Сan I change the magnification in the monocular to 1x?
My image freezes from time to time. Is this a defect?
During the calibration process the image freezes on the screen – this is normal and not a defect.
Default calibration mode is “Automatic” (the software decides when calibration is necessary) but you can change it to “Manual” mode in the "Main menu" => "Calibration mode" to calibrate the riflescope when you need to base on actual image quality. Please close the lens cover prior to manual calibration. We recommend using automatic mode all the time. Please read more about calibration in the user manual for your thermal device.
My image is blurry or out of focus.
Please make sure you have made the following adjustments:
Adjust the diopter adjustment on the eyepiece to clearly see the icons on the display and in the status bar.
Adjust the lens focus to see the object of observation clearly. Please note that re-focusing may be required as the distance to the object changes.
Do the image calibration – either in manual mode (with lens cover closed) or in automatic mode.
Select the most suitable amplification level – “Normal”, “High” or “Ultra” depending on the specific observation conditions.
Go through the different color palletes.
Manually adjust display contrast and brightness. We recommend keeping those two values at similar levels. A huge difference between them badly affects the image quality.
Check smoothing filter. If needed turn it on or off.
I can see a ghost image / residual artefact of the previous image. What is wrong?
You are using the manual calibration mode without closing the lens cover. Please make sure the lens cover is closed during calibration or switch to the automatic calibration mode if you do not want to close the cover.
I can hear a clicking sound during calibration. Can I turn it off?
No, a clicking sound is normal in the automatic and semiautomatic calibration modes.
You may switch to the manual calibration mode to avoid the sound. Remember to close the lens cover to make sure no ghost images appear on the display.
Why do I need to calibrate the image?
Calibration levels the background temperature of the microbolometer and eliminates image flaws (such as vertical stripes, ghost images of previous objects etc.). Intervals between calibrations depend on operating time: the longer a thermal imager operates nonstop, the less frequently calibration is required.
There are defective pixels (or pixel clusters) on the screen of my thermal imaging device.
Please note that a certain number of non-functional pixels (max 0.5% of total quantity) is allowed by the sensor and is not considered a defect. You may try repairing the pixels using the respective menu item of your thermal imager. For details, please refer to the user manual.

My Telos LRF is not measuring distance correctly.
Please take note of the following:
Accuracy of measurement and maximum range depend on the reflection ratio of the target surface, the angle at which the emitting beam falls on the target surface and environmental conditions. Reflectivity is also affected by surface texture, colour, size and the shape of the target. A shiny or brightly coloured surface is normally more reflective than a dark surface.
Measuring range to a small sized target is more difficult than to a large target. Accuracy of the measurement can also be affected by light conditions, fog, haze, rain, snow etc. Ranging performance can degrade in bright conditions or when ranging towards the sun.
When measuring range to a small-sized target located more that 400 meters away, it is recommended that you put your elbow against a solid surface. This is due to possible hand tremors and difficulty hitting the target with the beam at a longer distance.
How can I activate zoom?
To change the magnification, turn the digital zoom adjustment ring on the objective lens.
What battery is used in the Telos LRF? How can I charge the battery?
Telos devices use Li-Ion Power supply LPS 7i with a capacity of 6400 mAh.
The battery can be charged using a standard wireless induction charger (remove the battery cap before charging) or connected direct to the network adapter via the USB Type-C port.
Is it possible to use the Telos with a tripod?
If you want to mount the Telos LRF on a tripod, you need to use the Telos tripod adapter (bought separately). The Telos tripod adapter is equipped with a 1/4" tripod mount located on the bottom plane of the adapter.
How do I register my Telos LRF?

Night Vision Riflescopes
Can I use the riflescope in the daytime?
Yes, you can use the riflescope both at night and in the daytime.
For better performance in the daytime please close the lens cover and use the manual display brightness and contrast settings.
What mounting rings would you recommend for the Digex?
You can use all types of 30mm compatible rings and mounts.
There are no special recommendations – the rings should be good quality and sit as low as possible to facilicate zeroing.
You may also consider Innomount, this company produces mounts specially for our riflescopes:
Here is a catalog link.
When choosing rings, please take note of the dimensions of the riflescope.
My riflescope will not hold zero. What can I do?
Please make sure:
- your riflescope has the latest firmware version. Click here to check.
- you have correctly and firmly installed the riflescope on your rifle.
- you have correctly carried out the zeroing procedure described in the user manual.
The aiming reticle will not stay in the centre of the display after zeroing is done. Is it OK?
When setting the zeroing coordinates, the reticle moves along the image which allows a wider range of reticle adjustment.
The reticle movement range makes it possible to successfully zero a riflescope mounted even on a mount far from being ideal thus minimizing mount's faults. Higher precision of the rifle-mount system requires less movement of the reticle.
We suggest mounting the riflescope as low as possible and make sure there are no inclications in either side, especially vertically.
The supplied IR Illuminator lights excessively at a short distance.
The Digex uses a powerful IR illuminator. This increases detection range and gives the impression of a higher illumination when seeing objects at a shorter range. In such cases, we recommend the following:
- reducing the power of the IR illuminator;
- adjusting the position of the IR spot;
- holding the riflescope a little bit higher;
- using an alternative focusable IR Illuminator installed in place of the supplied IR.
Can I change the internal battery by myself?
The internal battery can be replaced only at the service centre. Please contact your seller or national distributor to arrange return for repair.
Does the riflescope support a remote control?
No, a remote control is not supported by Digex.
To control the riflescope remotely, you may use Stream Vision App available on
Google Play
App Store
Can I power the riflescope from a 12 V car adapter?
Yes, you can use a car adapter featuring 5V/2A output.
Does the riflescope feature Recoil activated video recording?
No, this function is not available. Please use the standard video recording function.
Are user zeroing profiles saved when updating riflescope’s firmware?
When updating firmware, user zeroing profiles are saved.
Why is the reticle off the centre after zeroing?
After zeroing the reticle may be slightly off the centre of the field of view which is normal and does not affect accuracy. If the riflescope is installed properly on your rifle, and the mount is well fixed too, you may not need to move the reticle a lot, thus the reticle will stay very close to the centre.
Does the riflescope save user zeroing profiles if it’s powered down for a long period of time?
Yes, user zeroing profiles are saved even if the battery is not installed in the riflescope for a long period of time.
My image is blurry when I use digital zoom. Is it a defect?
When using digital zoom, image is cropped so resolution will become lower and the image will look not as clear as when using the base (optic magnification).
It's a peculiarity of digital zoom in all devices, and it's not a defect.
Is it possible to upload new reticles to the riflescope?
You cannot do it by yourself. However you can send us a reticle type proposal and we will have it considered.
Can I use my Pulsar riflescopes on a SCAR 17s rifle known for its recoil?
All Pulsar digital and thermal riflescopes feature a max. shock resistance of 6000 Joules.
Please check this value for your cartridges.
Are the batteries charged or do they need to be charged before first use?
Products are supplied with partially charged batteries.
For better experience, we suggest fully charging the batteries before first use.
Please read the user manual for your device for extra information.
When can I use the color mode?
Along with the day use, we suggest using color mode in early and late stages of twilight. As the illumination level drops, please switch to the night (b/w image) mode. You can also use an active IR Illuminator (either supplied or an extra one). when it gets too dark.
Can I use the riflescope in the daytime?
Yes, you can use the riflescope both at night and in the daytime.
For better performance in the daytime please close the lens cover and use the manual display brightness and contrast settings.

Night Vision Front Attachments
Do I need to zero my Forward?
The device does not need zeroing. If you have installed the attachment correctly and firmly (using the correct cover ring adapter), the impact point should match the aim point.
I cannot see the status bar when using higher magnification in my optical scope.
The field of view of the Forward is 6.3 degrees, so you can see the full status bar if your scope's field of view is close to this value.
Please switch to lower magnification or connect your attachment to a mobile device via the Stream Vision Application to see the status bar fully.
What is the external size of the Cover Ring Adapters?

Can I use the parallax correction function in my day scope?
The eyepiece of the attachment is designed so that it may not adjust to the parallax settings of your day scope.
We do not recommmend using this function for short distances (such as 50m) to ensure the image is clear and focused.
Does the attachment support remote control?
Yes, it does support a wireless remote control. For details please refer to the link below: link
