FIELD: electronic equipment.
SUBSTANCE: invention relates to manual metal detectors. The essence of the invention consists in the fact that a manual metal detector automatically switches to a state of reduced energy consumption or a switched-off state when it is placed in a case and automatically switches to a working state when it is removed from the casing.
EFFECT: increase in the speed and productivity of searching for metal objects, an increase in the energy efficiency of the metal detector, an increase in the depth range when using the metal detector under water.
