Passwall Flashlight is a sonic weapon for agents that uses the infrasound human can't hear as a "bullet". It used high pressure gas and pipeline resonance to generate strong infrasound . Passwall Flashlight uses the high pressure vortex airflow to wrap the infrasound, so that the infrasound can only propagate along the pipeline direction, so as to achieve the purpose of not affecting agents and interfering with the enemy. This can provide a powerful condition for agents to perform secret tasks.Moreover, it is designed as a columnar flashlight, which is convenient for agents to carry and can meet the needs of night mission.
