The unique design of the WA Sinkers Gemini Breakout Sinker allows it to have distinct advantages over conventional break-out grip sinkers, other than the inter-changeability of the heads. 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!
