Depends on the size of the metal detectors, and the size of the metal under the surface of the earth. The bigger the metal detector, the bigger the piece of metal, the deeper down it will detect.

What are facts about metal detectors?
they detect metal
Can metal detectors detect objects in body cavities?
they mite
Can metal detectors detect mobile phones in a jacket?
yes
Can metal detectors detect money?
Basically No. But the detector have a camera then yes.
How are metal detectors used in an archaelogical studies?
there are traces of iron in the bone so the metal detecters can detect them :-)
Any metal detector available which detect iron and not aluminium?
Not necessarily. That would depend upon the metal detector design and the sensitivity settings.
Can precious metals be found outdoors using metal detectors.?
I have researched this topic and found that you can indeed find precious metals when using a metal detector. These metal detectors will detect items such as silver, iron, metal, gold and platinum.
Will heat change a rock so a metal detector will detect it?
No. Metal detectors actually detect anything that can conduct electricity. To make metal from rocks you would have to smelt them, and this requires both a lot of heat, and something like carbon to reduce the ore. However most rocks don't even have any ore so heat cannot change rocks so that metal detectors can detect them.
Can you set a metal detector so it will only detect lead?
Metal detectors are designed to detect all metals. However, many modern detectors have the ability to discriminate out metals of your choosing. You are basically setting the detector to remain silent when passing over the metals you don't want.
What is the difference between laser detectors and radar detectors?
Laser detectors detect laser speed devices and Radar detectors detect radar speed devices.Unfortunately it's usually too late when they detect Lasers.
Can metal detectors detect plastic?
it is head fry question u can't get the answer so leave this question and move forward
What is the average temperature of the water at the ma in hot springs?
Metal detectors have been a staple of airport security for decades. These tall, boxy metal detectors are meant to be walked through and, theoretically, they will detect any metal objects that pass through them. However, if this was the case, then there wouldn't be any need for the hand-held metal detectors that travel authority agents and security guards usually have. Knowing how the larger metal detectors work, and their failings, can help take the confusion out of any misunderstanding.
