What are the parts of a metal detector?
An industrial metal detector consists of four main components: the sensor, the control, the signal processor, and the output device. The sensor will react to the proximity of metal. The reaction of the sensor is transmitted to the filter, an electronic device that interprets the sensor signal.
How much depth does a metal detector need?
Detection Range: For 5 x 5cm objects, the instrument can detect at least 3.5 meters. Objects of 30 * 30cm can be detected in a range of 5 to 8 meters, and objects of this sizes can be detected in a range of 20 meters if they have been buried for a long time. With larger objects, with deeper detection depth.

What is the working principle of a metal detector?
Metal detectors work on the principle of transmitting a magnetic field and analyzing a return signal from the target and environment. The transmitted magnetic field varies in time, usually at rates of fairly high-pitched audio signals.

What is ground balance in metal detecting?
Ground Balance is a variable setting that increases detection depth in the mineralized ground. This ground may contain salts, such as in wet beach sand or fine iron particles, such as in red earth. These minerals respond to a detector’s transmit field in a similar way that a target does.
How far can metal detectors detect?
Are you curious about metal detecting, and wondering how deep a metal detector can go? Most metal detectors can detect objects about 4-8ʺ (10 – 20 cm) deep. In ideal conditions, a mid-range metal detector can reach 12-18ʺ (30-45 cm) underground. Some specialized detectors can go as deep as 65′ (20 m).
