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
Image Boost is not available as a dedicated feature but it’s incorporated in all observation modes.
Please take note of the following:
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.
No, restoring a previous firmware version is not possible.
Yes, you can use Thermion in any weather conditions (fog, rain, mist etc.), night and day.
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.
Please make sure:
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.
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.
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.
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.
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.
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.

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.
Yes, you can use a car adapter featuring a 5V / 2A output.
The internal battery can be replaced only at the service center. Please contact your seller or national distributor to arrange return for repair.
No, this function is not available. Please use the standard video recording function.
No, Thermion does not support a remote control.
To control the riflescope remotely, you may use Stream Vision App available on
When updating firmware, user zeroing profiles are saved.
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.
Yes, user zeroing profiles are saved even if the battery is not installed in the riflescope for a long period of time.
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.
You cannot do it by yourself. However you can send us a reticle type proposal and we will have it considered.
All Pulsar digital and thermal riflescopes feature a max. shock resistance of 6000 Joules.
Please check this value for your cartridges.
Yes, Thermion can be used on air/pellet guns.
Please make sure you follow all installation instructions
Thermion features a max. shock resistance of 6000 Joules.
Please check this value for your cartridges.
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.
All of our products, including Accolade 2 LRF, feature 1 Class Safety (standard IEC60825-1:2014) laser which means it's harmless to the eyes. Nevertheless, please avoid looking directly at the emitting lens of the rangefinder.
