Technically speaking it can detect through anything, however the depth at which it can detect will be effected by various factors such as density, moisture and more importantly base metals present in the sand and soil layer.
One of the biggest factors is metal density and variety in the soil layer. An area rich in a variety of metals will require a detector with excellent discrimination in order to decipher specific target metals or there will be too much background metal to find a specific object.
Basically it comes down the quality of the detector, the depth it can penetrate and the level of discrimination that it can be set to that will allow it to pick out specific metal combinations. A poor quality detector will get confused and go off constantly if there is a high volume of metals in the soil composition and if it lacks the ability to tune out the "background" noise of those metals.
Well, most metals can be detected by a metal detector, but some metals which are a mixture of metals and other materials may not be detected.
All Metals
maybe. ask the person running the detector.
no it just means it has a sparkle or shine to it as metal does
An alternating current is sent through the detector which creates an electromagnetic field. A piece of metal will disrupt this field and is detected by the magnetometer or another coil.
The metal interrupts or changes the field, and the detector senses the change.
One can purchase a Minelab metal detector as a precious metals show and convention or online at Amazon or any metal detector website. Plus shipping of course.
If there was nothing wrong then it had correctly detected something
Yes it can. It will be detected, but it will fit through.
Not necessarily. That would depend upon the metal detector design and the sensitivity settings.
i hope so. Because i lost my iPhone 4 in a snow that's up to my knees and I'm going to try using a metal detector to locate it.
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.
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.
