The INV56 can handle trashy sites due to its DD configuration, which maintains target separation better than concentric coils in iron-contaminated ground. However, the 22x19 coil size makes it less maneuverable in tight spaces and more likely to detect multiple targets simultaneously in dense trash fields. If you're working a park with heavy aluminum and iron debris, a smaller coil will give you better target isolation and easier pinpointing. The INV56 is better suited to open ground with scattered targets where its coverage advantage outweighs the need for tight target separation. For trashy urban sites, stick with a smaller coil and switch to the INV56 when you move to open fields or beaches.
