A searchcoil is the most vital part of a hobby detector. It is the device attached to the control housing, which “connects” the metal detector to the ground beneath it. It contains a transmitter and a receiver, which help the detector retrieve and interpret information about a detected target. Searchcoils are available in several shapes and sizes to meet a variety of hunting needs. Generally speaking, small searchcoils are designed to detect small shallowly buried objects, while large searchcoils are used to find large, deeply buried objects, such as relics and Caches. Coils can range in size from four to 12 1/2 inches in diameter. An all-purpose detector usually comes equipped with an eight- or nine-inch searchcoil that is practical for scanning parks, playgrounds, beaches and other popular coin-hunting locations. A small searchcoil is often used in very trashy areas because its magnetic field penetrates a small area and therefore is less likely to pick up unwanted targets like trash.
