1. A submersible member comprising:
an elongated body defining an outer body surface, the body defining a top end and a bottom end;
a base electrode comprising an electrical terminal extending through a recessed base electrode pocket of the outer body surface of the elongated body;
a first conductive member extending through the body from the top end to the base electrode, the first conductive member connected in electrical communication with the base electrode;
an indicator electrode extending through a recessed indicator electrode pocket of the outer body surface of the elongated body, the indicator electrode positioned between the top end and the base electrode; and
a second conductive member extending through the body from the top end to the indicator electrode, the second conductive member connected in electrical communication with the indicator electrode, wherein an electrical polarity of the electrical terminal of the base electrode is opposite the electrical polarity of the indicator electrode, wherein the indicator electrode is a cone point set screw, and wherein the indicator electrode is screwed into a bore of the body and tightened until the cone point enters the second conductive member.
