While a standard coil is great for finding large objects that are deeplyburied, the 4-inch coil has a narrower field of detection - enablingyour detector to separate objects more efficiently.
The 4-inch coil’sshallower detection area makes it ideal for prospecting in difficult,high metal areas since it allows you more easily to discriminatevaluable objects from refuse. In addition to allowing the precisepinpointing of objects, a smaller coil lets you probe tight spots suchas corners and crevices.
