The SD2100v2 has the ability to cancel out the effects of ground mineralisation so that it minimises ground noise while still retaining maximum sensitivity to metal targets Cancelling out the effects of ground mineralisation is referred to as ground balancing This ensures that welcome signals from objects such as gold are not confused with unwelcome ground noise The Balance 1 and Balance 2 contro...

Minelab suggests you start digging about 100mm in front of the target to reduce the chance of damage Pile the diggings carefully as it might be necessary to search them systematically later They must also be replaced just as they were dug once your search ends If it becomes evident that the target is in the removed soil pile sweep the coil over the pile and pinpoint where it lies Progressively ha...
