The Breakout Sinker Glow In The Dark from GEMINI has clear advantages over conventional breakout grip seamen, apart from the interchangeability of the heads. Because the nose cone places the grips in front of the lead sinker mass, it changes the center of gravity, increasing the pressure on the grips in the seabed. To test this, place a Gemini sinker next to a conventional equal-weight sinker, then place your finger on the nose cone and push it back. The Gemini sinker will be noticeably harder to push! In addition, it contains a glow in the dark matter with a luminus function.
