When you increase the diameter of the coil there is a reverse effect. Work with the metal detector as follows. Placing the search coil in close proximity to the Earth’s surface, adjust potentiometer R2 generator. So that the primer in a telephone sound not auditioned. When the coil is above the Earth’s surface (very close to the last) and one looks for the coveted seat on a sound in telephone primer.

What is the structure of a metal detector?
The structure of a metal detector can vary depending on its type, purpose, and complexity. However, most metal detectors share some common components and features. Here is a typical structure of a basic metal detector:
The control box is the main housing of the metal detector that contains the electronic circuitry, controls, and often a display interface. Users interact with the control box to adjust settings and receive feedback.
Stem or Shaft:
The stem, also known as the shaft, is the structural component that connects the control box to the search coil. It is usually adjustable in length to accommodate users of different heights.
The search coil, also called the scanning head or antenna, is a crucial component that interacts with the ground. It is typically located at the end of the stem and is responsible for emitting and receiving electromagnetic signals.
Some metal detectors feature a stabilizer, which is a structural component near the handle or control box designed to balance the weight and improve handling during use.
Handle or Grip:
The handle provides a comfortable grip for the user to hold the metal detector. It is usually attached to the control box and may contain additional controls or buttons.
The control interface, often located on the control box, consists of buttons, knobs, and a display screen. Users can adjust settings such as sensitivity, discrimination, and volume through this interface.
Metal detectors are typically powered by batteries. The battery compartment, usually located in the control box, holds the required batteries (e.g., alkaline or rechargeable batteries).
The coil connector is the point where the search coil is connected to the control box. This allows the coil to receive power and send signals to the control circuit.
Some metal detectors have an armrest attached to the stem near the handle. The armrest provides additional support and comfort during use.
Many metal detectors include a headphone jack, allowing users to connect headphones for private audio alerts without disturbing others.
The metal detector may have an integrated speaker to provide audible signals when metal is detected. Some models may allow users to switch between speaker and headphone output.
It’s important to note that more advanced metal detectors may include additional features, such as digital displays, advanced discrimination settings, multiple search coils, and waterproof designs for underwater use. The specific structure and features can vary based on the brand, model, and intended use of the metal detector.
