The unique design of the Gemini system 100+ breakout sinker, has distinct advantages over conventional break-out grip sinkers. Because the nose cone places the grips in front of the mass of the lead sinker, this alters the centre of gravity, bearing greater pressure on the grips into the sea bed. To test this, place a Gemini sinker alongside a conventional style sinker of equal weights, then, in turn, place your finger on the nose cone and push backwards. The Gemini sinker will be noticeably harder to push! The unique Gemini design allows the four individual grip wires to be preciseley tensioned on the extremely hard wearing plastic head.
