The RC40's larger 15.5" x 13" footprint provides greater depth on coin-sized targets compared to smaller stock coils, with even greater gains on larger cache-sized objects. The exact depth increase depends on ground mineralization, target size, and your detector settings, but the larger electromagnetic field penetrates deeper into the soil in all conditions. You'll notice the biggest depth gains in open fields and beaches where the larger coil can work without interference from dense trash. In trashy areas with multiple targets close together, the stock coil may actually outperform the RC40 because smaller coils offer better target separation.
