General questions

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).

No, there are no thermal imagers able to look through glass because glass does not let infrared radiation within 8–14 ɥm pass.

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.

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.

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.

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. 

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.

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.

This can be solved by updating firmware for selected products. Please check if there is a new firmware for your device here.

For devices not on the list, to play the sound, please download video to your iPhone and use an alternative media player such as VLC.

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.

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.

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.
