The Centre Of Gravity (COG) rig is a form of semi-fixed rig by Korda where the hooklink is directly attached to the middle of the mass of the lead in order to maximise the hooking effect during a pick up.
A bespoke lead is required which has a rubber lined hole in the centre of the lead, into which fits a bespoke swivel. Upon this swivel the hooklink is mounted, but a secondary line is also attached to this swivel and this runs to the mainline.
The mainline splits into two with one link going to the end of the lead in traditional fashion, and the other connecting to the COG swivel as above.
The hooklink swivel can pop out of the rubber lined hole, and the bait and the lead are still attached to the mainline.
