Yes, you can use Trail 2 LRF in any weather conditions (fog, rain, mist etc.), night and day.
Please refer to the user manual available online.
Also, you may find useful our zeroing guide on youtube.
The recommended clamping force is up to 2–3 Nm. Please note that applying thread sealant is very important.
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.
Please note that a certain amount of non-functional pixels (max 0.5% of total quantity) is allowed by the sensor producer and is not considered a defect.
You may try repairing the pixels using the respective menu item of your thermal riflescope. Click here to view sample video instructions.
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.
It is not possible to turn off the reticle in Trail. For observation purposes,
you may choose Reticle "D50i" in the menu which takes the minimum area of the display.
No, this function is not available. Please use the standard video recording function.
Yes, it's the way it should be.
The rangefinding reticle is always in the center of the field of view.
The aiming reticle after zeroing may be slightly off center which is normal and does not influence shooting accuracy.
Please take note of the following:
All of our products, including TRAIL 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.
No, the Trail 2 LRF does not support remote operation.
To control the riflescope remotely, you may use the Stream Vision App available on
Yes, you can use a car adapter featuring 5V / 2A output.
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.
Trail 2 was not tested specifically on SCAR rifles
but the riflescope was tested on a shock resistance stand in both directions backwards and forwards.
We know that Trail 2 is used by customers and we heard no issues from them.
Please make sure you install the mount and the riflescope on the rifles
according to the instructions.
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.
No, restoring a previous firmware version is not possible, to do that, please send your device to our service centre.
The gun is equipped with a compensator or silencer that radiates heat when fired.
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.
