The INV40 coil's 15.5" x 14" footprint provides wider ground coverage per sweep compared to smaller coils, which reduces the number of passes required to search a given area and increases efficiency during long detecting sessions. Larger coils detect deeper targets on larger objects such as relics, caches, and deep coins, making the INV40 particularly effective for open-field relic hunting and beach detecting where coverage speed and depth matter most. The Double-D configuration maintains target separation even at depth, so you're not sacrificing discrimination for size. This combination of wide coverage and DD design makes the INV40 ideal for efficiently searching large open areas while maintaining the ability to distinguish between targets in trashy conditions.
