Hello the 11x13 is an enclosed Mono coil that provides the most depth on small targets. It is enclosed to prevent snagging the coil on brush or rocks and makes it easier for prospectors to lay dirt on the coil while looking for tiny targets in the field. The 10x12 is more of a classic DD coil with an open design. Both coils are Pulse Induction and extremely sensitive. Thanks for contacting us!
