What are the factors that affect the detection distance of metal detectors?
1. Detected metal
The detection depth of metal detection equipment has a great relationship with the area, shape and weight of the metal to be detected. Generally speaking, the larger the area, the greater the number, and the greater the corresponding detection depth. Conversely, the smaller the area, the smaller the number, and the smaller the corresponding depth.
2. Soil quality
The detection depth will be different under different soil conditions. For example, if the soil is relatively wet or dense, the signal strength of the detected metal will be weakened, thereby reducing the detection depth of the metal detector.
3. Metal burial time
The farther the metal is buried, the deeper the detection depth, because the metal will gradually oxidize after being buried in the ground for a long time, and the metal rust will spread around and react with the surrounding soil, generating a stronger magnetic field, which will increase the area of the metal and increase the area of the metal. The strength of the signal.
4. The size and shape of the metal
Target size, under the same environment, the larger the target volume, the wider the signal range, the deeper the detection, and vice versa. The shape of the target, a coin lying flat is usually deeper than a very long wire detection depth, the larger the cross-sectional area, the deeper the detection.
5. Technical experience
The same metal detector, the same target, experienced veterans must detect deeper and more accurately.
