[QUOTE="AuMan, post: 511808, member: 2670"] Of course they all have shielding, they won't work without it. My point is that the detector body is not grounded to earth(the thing we walk on), so is able to build up charge and then at some point it discharges into ground when you brush some random rock or shrub(the gap is close enough for a discharge to occur). Just to be clear, the detector body, coil shielding and detector electronic ground are all connected to detector ground, but the detector as a whole unit is isolated from earth(plastic coil housing, plastic feet on the detector, plastic handle), therefore in the right conditions is able to build up charge. You will notice this more on hot dry windy days. Cheers Mick [/QUOTE]
