Abstract:
1. An electrode for electric survey, comprising: a first electrode rod comprising a linear rod that includes a head portion at a first end, a tip portion at a second end, and a body portion between the first end and the second end, and a second electrode rod in electrical connection with the first electrode rod and coupled to the body portion of the first electrode rod, the second electrode rod including a first portion extending from the body portion of the first electrode rod, and a second portion defining a first end and a second end, the second portion connected to the first portion at the first end such that the second portion extends essentially transversely from the first portion so as to be essentially parallel to the first electrode rod; wherein the second portion of the second electrode rod is provided with a resilient connecting spring defining a fixed end and a free end opposite the fixed end, the fixed end of the connecting spring detachably secured and connected to the second portion thereby causing the free end to be pressed toward, the second portion such that an electrical wire received between the free end and the second portion is pressed against, and in contact with, the second portion causing the electrical wire to be detachably in electrical connection with the second portion.
