Depth of detection

Please note: the detection depth is mainly based on the size of the area of the metal to decide, the larger the depth of the metal area the deeper, the smaller the shallower. Instead of the machine labeled a few meters is the size of any thing can be detected a few meters! For example, a coin, silver dollar, etc. want to detect a few meters, that is impossible Oh! Imagine if this who still need to go to work? The depth of detection is also closely related to the local geomagnetic field, the degree of oxidation of the object (years of burial), the geographic environment and soil structure, the variety of minerals and the physical depth, size, and commissioning of the user.
