Graviton putty has a high-Tungsten, heavy-weight content that hugs the contours on the bottom of the lake and sinks quickly. The Tungsten in Graviton putty has a relative atomic mass (Ar) of 184 - one of the heaviest elements in the entire universe - and a high-density of 19.25g/cm3. Warm the putty in your hand for a while and it will become soft and sticky, and pliable to your chosen material. Once applied and in the water, the putty will harden off and grip firmly. Many anglers consider Graviton to be essential for correct rig presentation - use it and improve your catch rate. Ideal for pinning down chod and bottom rigs. Available in Weed Green or Choddy Silt colours.
