ABSTRACT:
The invention is for controlling electrical potential of a downrigger wire line as used in downrigger fishing. The apparatus has a conducting member with an opening to receive the downrigger wire line to permit the wire line to pass freely therethrough. The conducting member has at least a contact portion which is electrically conducting and which contacts the downrigger wire line to provide electrical contact therewith. The contact portion is electrically connectable to an electrical voltage source to provide an electrical potential to the downrigger wire line. A main electrical conductor connected to the contact portion is also preferably connected to a portion of the downrigger so as to partially locate the conducting member which is also partially supported on the downrigger wire line. Preferably, the conducting member is a sleeve which at least partially encloses the downrigger wire line. Thus, an accurately controlled electrical potential is transferred directly into the wire line, without passing through intermediate portions of the downrigger apparatus. This permits control of electrical potential of a downrigger wire line of a recreational downrigger, in which the wire line is commonly wound on an insulating plastic reel or spool and passes through an insulating plastic pulley at an end of the downrigger arm.
