1、 What is a metal detector

A metal detector is an electronic instrument that detects the presence of metal in its surroundings. Metal detectors can be used to detect metal inclusions within objects or metal objects buried underground. Metal detectors typically consist of a handheld device and a sensing probe that can scan across the ground or other objects. When the detector approaches a piece of metal, the headphones will emit a transition sound or the pointer inside the indicator will move. Usually, the detector will indicate the distance of the metal, and the closer the metal is, the higher the tone inside the headphones or the higher the pointer inside the indicator.

　　2、 Reasons for the different prices of detectors

Many new explorers have a question when asking about detector prices, why do all detectors look the same but have significant price differences.

The appearance of metal detectors looks similar, but the technology used in each product is not exactly the same. Detectors, like other products, have performance that is directly proportional to their price. The price of a detector varies depending on its performance and the technology used.

The frequency emitted by the detector: The frequency (kHz) emitted by the detector underground is measured in kilohertz. The lower the kilohertz value of the frequency, the deeper the signal reaches. The higher the frequency value, the higher the sensitivity of small items on the ground.

There are two types of detectors: treasure detectors and gold detectors. The treasure detector has a metal recognition function, which can indicate the type of metal. Obviously, the more accurate and precise the metal recognition function, the more expensive the price will be,

A gold detector is specifically designed for detecting gold and does not have the function of metal identification. In areas where gold is produced, there is a high level of surface mineralization, requiring the detector to have good ground balance to eliminate surface mineralization while maintaining exploration depth and sensitivity to gold nuggets. So the ability of ground balance, noise cancellation (selectable frequency), and machine sensitivity all determine the difference in price.
