Why cant metal detectors have longer ranges like 100 meters or higher?

Metals time around aura of magnetism create
And generated spiral waves that can be identified from a distance

There is a device sold by Accurate Locators something like AGR receiver. It is a receiver that they say a local radio station can reflect off say a gold target at a certain fraction of the original frequency (depending on the resonant frequency of the desired target).

Thanks Mike, good explanation

I don't know where he came up with his theory. I mean the part about a fraction of the resonant frequency. I understand when an object radiates it does so at a lower frequency, but just exactly what frequency? The idea that a given radio station can cause the excitation is fine, but when you have so many different stations the radiated frequencies are going to be all over the scale and it seems likely that other elements will interfere. Now I'm not stating this as fact, just seems that way to me. Maybe it's not an issue.

It shouldn't make any difference. You just have to believe, then it will work. As long as you also supply the necessary elements of selective memory and self delusion.

That's a happy condition to have. If you had to be concerned about all those different radio stations and harmonics, it might cause your head to explode.
Hopefully there's some law of science that makes the millions of frequencies fizzle away when you get farther away from them.
A treasure hunter might need to study RF propagation to see what are the implications to "Phenomenon" sensors.

Better yet, just believe... and be happy.

, just

Yeah, well you guys are the ones who don't have an LRL. Or should I say you have convinced yourselves that it can't possibly work. I'm not against the pistol type detectors, just haven't seen or heard of anything of that type that can begin to compete with the frequency generators. And I have built other types of locators that rely a little more on dowsing. So who is delusional here? Reminds me of the Elvis song Hound Dog.
