The widescan coil is less affected by mineralization than the concentric, so it is generally used for gold prospecting or relic hunting in highly mineralized ground. Pinpointing is done with the heel or toe of the coil. There are many different sizes of coils available and each one may fine tune your hunting but only if you get the correct size. Larger coils go deeper than smaller coils but only on larger targets.
When using a large coil, you may lose sensitivity to small targets. A large coil is also more susceptible to masking. Masking happens in the discriminate mode when a good target and junk target are both under the coil at the same time.Masking is very common in junky playgrounds and in-and-around old house sites. Smaller coils will concentrate the signal and make the detector more sensitive to the little targets. Unfortunately, smaller coils tend to lose depth when compared to their larger cousins. Being that these coils dont have as wide a search pattern, they are also less likely to mask targets in trashy hunting situations. Knowing where you are going to hunt and what you are hunting for goes a long way in choosing the right coil for your needs.
A larger coil is used to hunt in a clean area and/or for relics that may tend to be deeper. A small coil will help to find the smaller targets such as gold nuggets or fine jewelry. Small coils can also be used to hunt for coins & jewelry in extremely trashy sites. The length and width of the coil affects different aspects of its performance.The length of the coil (toe-to-heel) affects your coverage area, while the width (side-to-side) affects the depth. For example, the 3x18" cleansweep coil is 3" wide by 18 long. The 18" length provides a very large coverage area, but its 3" width indicates depth similar to a smaller coil. Most coils are available with a short or long cable. The short cable is approximately 3½' long and is suited to accomodate the length from the housing to the coil. The long cable is approximately 8' long, and allows for the housing to be removed from the pole and worn on the hip (only applicable to water units and Lobo ST).
