A tool for visualizing invisible and inaudible ultrasound.

The ultrasound emitted by "Evasi" is mostly inaudible to humans. In the past, the only way to confirm whether ultrasound was being emitted was to use large measuring devices, but we have made it compact and lightweight for easy portability. With this single device, you can easily check whether the ultrasound is properly reaching the desired location.
