Simple Checker
A tool to visualize invisible and inaudible ultrasound.
The ultrasonic waves emitted by "Evasi" are mostly inaudible to humans. In the past, the only way to confirm whether ultrasonic waves were being emitted was to use large measuring devices, but we have made it compact and lightweight for convenient portability. With this single unit, you can easily check whether the ultrasonic waves are properly reaching the desired location.
