Gemini Breakout Sinkers

The unique design of the Gemini breakout sinker has distinct advantages over conventional break-out grip sinkers. The nose cone of the Gemini sinker 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 weight. Then, in turn, place your finger on the nose cone and push backwards.
