Helion 2 Pro features:
- a ground-breaking temperature sensitivity (NETD lower than 25 mK) enabling detection of the smallest temperature differences.
- improved F50/1.0 objective lens with improved heat energy transmissivity.
All specifications you can find here.
Please make sure you have made the following adjustments:
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.
No, it's not possible.
Helion monoculars manufactured use ULIS thermal sensor (France).
The Helion 2 Pro is a purely handheld device that cannot be mounted on a riflescope.
No, using Image Detail Boost for a long time cannot damage your device.
No, Helion does not have a temperature measurement function.
Yes, you can connect your Helion 2 Pro via the supplied USB cable to a 12V car adapter.
Recommended output is 2A, lower output charge time will be longer.
Helion series can be used with both hands, but the hand strap cannot be placed on the left side.
It's only AXION XM30S that is adapted for left hand users -
you can install the hand strap on both sides:
