Helion 2 Pro

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:

• First, adjust the diopter adjustment on the eyepiece to clearly see the icons on the display and in the status bar.
• Second, 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 observation mode – “Forest”, “Rocks” or “Identification” 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.
• Try turning Image Detail Boost ON and OFF. The greatest benefit of this feature can be enjoyed in scenery with high contrast and at shorter distances.

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.

There could be an issue with the thermal sensor. 

Please contact your seller or our official distributor in your country to have your device inspected.

Please press calibration button again – the shutter should work now.
If this does not happen, please send your device to your seller or our official distributor in your country  to have it fixed. 

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:
