no it just means it has a sparkle or shine to it as metal does
maybe. ask the person running the detector.
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.
If there was nothing wrong then it had correctly detected something
Yes it can. It will be detected, but it will fit through.
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.
All metal detectors detect all metal depending on the level of sensitivity they are set at. Battery or no, a cell phone would be detected.
metal detector is sensor
A metal detector can detect all types of metal....depending on in what type of soil it is in.
A metal detector will not find vegetable matter.
The metal detector was invented in 1931 by Gerhard Fisher.
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.
