The Kodex Graviton Tungsten Sink Beads come under the beady eye of Angler's Mail tackle editor Richard Howard. He's the No.1 products inspector, checking out loads of quality kit every week.

THE Kodex Graviton terminal tackle range helps ensure that your end tackle remains pinned to the deck around your bait, so that Mr Carp can’t detect it.

Accompanying their Super Heavy Tungsten Putty, and Tungsten Rig Tubing are these Tungsten Sink Beads.

The Tungsten used in the range has an atomic mass of 183.8 – one of the heaviest elements in the universe.

These beads are designed to add weight to your rig set-ups, and they have a tapered hole to allow them to grip different diameters of end tackle component.

I like the pleasing, matt finish and rig-concealing colours, which are Mud Brown, Chod Silt and Weed Green, too.

Price: £3.75 for a pack of 12.
