【All-Frequency Sensitive Bug Detector】 You often see it in the news, but recently many people are being spied on and bugged. With this, you can live with peace of mind. This is a bug detector that senses all radio waves, from low to high frequencies. It reacts not only to bugs but also to any device emitting radio waves when brought close. This bug and spy detector can sense radio waves across a wide frequency band of "1-6.5GHz". It can also alert those around you with a loud sound if you are in danger while out. A strap for carrying outdoors is also included. It can also be attached to windows and other places to prevent intruders. I usually attach a few to my windows. It comes with a convenient charging cable. Since the box is 32mm wide, I will send it after removing it from the box. The box will be folded and included. An instruction manual is also included.
