we don't sell this product but we will give you infos about the product and this app show you how metal detector work

A metal detector is an electronic instrument which detects the presence of metal nearby. Metal detectors are useful for finding metal inclusions hidden within objects, or metal objects buried underground. They often consist of a handheld unit with a sensor probe which can be swept over the ground or other objects. If the sensor comes near a piece of metal this is indicated by a changing tone in earphones, or a needle moving on an indicator. Usually the device gives some indication of distance; the closer the metal is, the higher the tone in the earphone or the higher the needle goes. Another common type are stationary "walk through" metal detectors used for security screening at access points in prisons, courthouses, and airports to detect concealed metal weapons on a person's body.

The simplest form of a metal detector consists of an oscillator producing an alternating current that passes through a coil producing an alternating magnetic field. If a piece of electrically conductive metal is close to the coil, eddy currents will be induced in the metal, and this produces a magnetic field of its own. If another coil is used to measure the magnetic field (acting as a magnetometer), the change in the magnetic field due to the metallic object can be detected.

The first industrial metal detectors were developed in the 1960s and were used extensively for mineral prospecting and other industrial applications. Uses include detecting land mines, the detection of weapons such as knives and guns (especially in airport security), geophysical prospecting, archaeology and treasure hunting. Metal detectors are also used to detect foreign bodies in food, and in the construction industry to detect steel reinforcing bars in concrete and pipes and wires buried in walls and floors.

Nokta AU Gold Finder Metal Detector
with 10x5.5" and 5" Waterproof DD Search Coils, Headphones, Coil Covers and a Hip Mount Belt. *Ships World-Wide*

Going for the gold has never been easier than with the Nokta AU Gold Finder Metal Detector! This deep seeking gold machine was built to find large and small nuggets in any terrain. The AU Gold Finder utilizes automatic, tracking and manual ground balancing for maximum cancelization of highly mineralized soil. Operating at a 56kHz frequency, this device provides the ultimate in sensitivity and depth when hunting for gold.

The AU Gold Finder features three distinct search modes for a better gold hunting experience. The ALL METAL Mode penetrates the farthest into the ground and is great for finding just about anything. The DISC.1 FAST Mode was programmed for gold hunting in fields with high mineralization or significant quantities of conductive rocks. This mode improves target detection and recovery speeds in areas where there is a lot of trash. The DISC.2 DEEP Mode gives the user a two tone discrimination setting designed for gold fields with less mineralization or hot rocks. It provides an increase in depth performance while still being able to pinpoint large and small gold nuggets.

The AU Gold Finder features easy-to-use switches and knobs to take the guess work out of operating the device. It even comes with IP54 Rating which protects the metal detector from any dust or water spray. To top it all off, the device includes two waterproof DD search coils (one 10x5.5" and one 5") and two search coil covers for the ultimate protection.
