I have one that finds buried pipes and wires. There is a spot where I usually park the big tractor. Months after I moved the tractor it can still find the outline of the tractor. It can find the spot where the plastic water line is but it cannot fine a 10 inch metal gas line under the back pasture. I have another that screams for the 10 inch metal pipe but can not find the water line. There is some black magic and a big load of faith in this.
Perhaps that someone is confusing the feature of some detectors LCD displays that will show an ICON of a coin, or jewelry and such once that specific type of metal has been located. I've seen those types of detectors on the market. It's nothing more than bells and whistles for novice hunters.killivolt said:I just wanted to know about something. I had someone tell me that a newer design Metal detectors can create an Image of what it found as well as tell the value the image produced. Copper,Gold, Ect ?

I beleive the image is determined by the strength or weakness of the change in the magnetic field. If ab=34khz which is the coil signal, c=copper g=gold,I=iron,etc Each will change the singal, to what degree I have no clue.
these signals are sent to micro-processor, where the changes are processed,and it makes an educated guess. Also most of them say dig every signal.
