fast facts about metal detector

Let us talk about metal detectors.
Most detectors have a maximum depth ranging from 8 inches to 12 inches. The depth is affected by several factors.
• The type of metal detector – VLFs and PIs are more accurate than BFOs.
• The type of metal present in the object – objects with iron produces stronger magnetic fields
• The size of the object – smaller objects are harder to detect
• The composition of a soil – a disadvantage, since there are minerals that act as metal conductors.
• The interference of other objects such as pipes, cables, and power lines present in the ground
• The items halo – if a metal has been buried in the ground for a long time, it is able to affect the soil by increasing the conductivity of the soil.

Since that we have come to this metal detector topic let us also consider its uses and applications especially when in work-related to metal detectors uses a variation of the PI technology, but most of the handheld devices use the BFO technology. Its use at work can be seen in:
• Airport/building/event security – for scanning the luggage and those who are entering the airport/building/event to ensure the safety of the majority
• Item recovery – used to recover lost items such as jewelry
• Archaeological exploration – for detecting significant metallic items.
Aside from treasure hunting, metal detectors give individual leisure:
• Coin shooting – hunting for coins, be it old or current coins. Coin shooting is usually done in beach or after an event, such as a concert.
• Prospecting – aims to detect valuable metals such as gold nuggets.
• Relic hunting – detecting metals with historical value, such as weapons used in civil wars.
