Electricity

Hi,

If I put two copper rods(24 inches) in the ground and then put jump cable on a 12v car battery and connect + and _ on each copper rods, how it-is possible to find a silver coin or a non ferrous coin at 15 inches with a standard metal detector? Anabody ever try that or something similar?

Hi
I have not, but may i know why you ask, did you try this ?

Hi,

First, sorry for my inglish...it's not my first language! No, I didn't try this method but I see something advertised on the net. I'm a serious coinhunter looking around for someting different.

Hello:
Not, the 12 volts energy, not work, you need use a alternate current.
I bulid a inverter, run with 12v, but out is 24vac, I not try with 127v and I put 6 electrode in one side and other 6 in the other side. In my country people call this a "tendido" this current "find" lost metals in the ground.

Hola:
No, la energia de 12 volts no te servira, debes usar corriente alterna.
Yo construi un inversor, trabaja con 12v, pero la salida es 24 vac, Yo no he intentado con 127v y yo puse 6 electrodos en un lado y 6 en el otro lado. En mi pais la gente llama a esto un "tendido" esta corriente "encuentra" metales perdidos en la tierra.

Thanks Agraz.

Compas built a machine called a depth doubler it basicly puts an electrical charge into a specific chosen area, they say this is similiar to hunting an area after a lightning storm, the ground is a lot more sensitive to the signals from a metal detector. Cost was around $350.00 10 years ago.
