The Galvanic Contact pads are for use in situations where you cannot insert pins/probes into the ground because of the damage they cause.

The Pads attach to the C1, P1, P2 and C2 connectors of the TAR-3 Resistance Meter using crocodile clips and the cables supplied with the TAR-3 System. The pads must make a good electrical (galvanic) contact with the ground. You can use blotting paper soaked in a solution of salt (NaCl) or a paste made with saline solution mixed with Bentonite (or Kaolin, etc.) to ensure that they have intimate contact.
