These tungsten impregnated Anti-Tangle Sleeves are part of our Dark Matter range, and are designed to help to kick your hook link away from the lead when it hits the bottom, and also to stop tangles during flight. The Dark Matter Tungsten Anti Tangle Sleeves are finely tapered and made from a supple rubber which can easily be pushed over a size 8 swivel, or similar hook link attachment, and are available in either a Short or Long version to cover any type of presentation or set-up. The rubber used to make these sleeves has been impregnated with a high level of tungsten, to help keep your rig nailed to the deck. Each pack contains eight sleeves.
