Explanation:

There are a number of factors that affect the detection sensitivity of a metal detector and the ability to find different types of metal. It’s important to understand these factors to get the most out of your metal detection program.

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. Performance is usually expressed in terms of the diameter of a test sphere made from a specific type of metal, such as ferrous, non-ferrous, aluminum or stainless steel. The higher the sensitivity of the metal detector, the smaller the pieces of metal it can detect. It is a clear ideal, but one that is complicated by a number of factors.

We regularly refer to the diameter of a ball size when discussing detection sensitivity. For example, a highly sensitive detector could detect a 0.6mm ferrous ball. The effect of the ball size is small but real life, metal contaminants can be much larger. Therefore, small changes in detecting ball size can make big changes to the size of metal contaminants that can be found.
