Coil selection basics- When choosing a coil there are a few basics to remember that relate to the size, shape, configuration and frequency of the coil. Size- The size of a coil can influence the detection depth and sensitivity of a detector. The larger the coil, the deeper it tends to detect, but with less sensitivity to small targets. The smaller the diameter, the more sensitive it becomes, but with reduced detection depth. Smaller coils are lighter in weight, easier to control and may be chosen for their ability to negotiate difficult terrain or undergrowth. Smaller coils also have a target separation advantage in areas of high trash, due to their smaller detection footprint. Shape-  The most common coil shapes are round and elliptical. They are available in solid and open-web designs. Elliptical coils are more maneuverable
