So you think wire conductors in cables are directional? Think again...

Funny thing is there are numerous examples of people having something very much akin to sonar. It generally is referred to as echolocation, and has been the focus of some experiments/studies, scientific-like and everything ( they probably even use voltmeters and stuff ).

Can these people maneuver in a dark room? No because they are not bats. There is a difference from having some special skills vs. actually possessing capability that can paint the surrounding with sound.  Bats can do that and dolphins can but human can't.

many blind people see with sounds it is a common place fact illustrating the human abilities like animals...

This case of Ethan and daniel is pure echolocation in human

 There is more in  human perception that there is in a voltmeter....

 That does not means that cable direction exist.... That means we cannot trust a frequencies meter to know it exist or not .... Saying the opposite is faith in a witch called technology.... Technology is NOT science by any means....

I am curious to know why if they could, why would they still need a stick to go around? Maybe in some special cases, but I could only see two vid on youtube.

I do recall some circumstances where people claim to have cured their cancer with their mind, but there are on a few reported cases.

If you dont trust youtube :

Why human use stick unlike bats and dolphins?

Because they take advantage of their hands and because they walk on solid earth they dont swim or fly...
