What does target mean on a metal detector?
Then, when you look at the LCD display on your detector, you’ll see numbers and/or bars illuminated on the screen. This is the Target Identification indicator. It indicates which type of metal is being transmitted. Usually, the target Identification has an iron section, a gold range and a silver range.
How many feet can a metal detector detect?
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).
What does ground balance mean on a metal detector?
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 does sensitivity work on a metal detector?
Sensitivity is the measure of a metal detector’s ability to detect a specific type and size of metal contaminant. The better the sensitivity of the metal detector, the smaller the pieces of irregular-shaped metal it can detect.
What does the big number on a metal detector mean?
It’s essentially a numeric measurement, typically on a scale from 0 to100 that represents the conductivity of the target. It’s not fool proof, but in general, iron is the least conductive and gets a low number whereas aluminum and silver are very conductive and get very high numbers.
How far underground Can a metal detector 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).
