Description

1 Description A ground loop system consisting of a coil loop or multiple loops that can be placed on or near to the ground. The loop or loops are connected to a power supply and electronicly controlled switched energising system. The energising system controls the amount of and /or the duration of the energy being coupled into the coil loops. The energizing system is controlled by a receiver that is recieving control signals from a separate transmitter that is being controlled from a separate metal detector device such as existing pulse or induction type metal detecing apperatus as for example commonly available metal detectors. A receiver and transmitter are coupled to the metal detector unit, the receiver intercepts the transmitted information from the metal detector coil or transmitter electronics and this information is then transmitted to the reciever coupled to the ground loop coil or coils energising transmitter system.
