Machines come with a standard coil, but you can also choose a different coil in terms of type, quality and size for your detector. Indeed, the size of a coil has a direct influence on how deep your machine can detect. It also influences its sensitivity. In other words, the larger the size of the coil, the deeper it will be able to detect.
