The principle of bird net

The principle of bird net is to use different frequencies to emit different induction bands. The working principle of the bird catcher is to emit different wave bands and different induction bands with different frequencies, and to carry out induction attacks on different animals, which is the attack effect in the target's mind. If the wave band emitted by the ultrasonic bird catcher is just close to the active wave in the target's mind, it will achieve the attack effect and stun the target.
