ESP Marker Gum is the perfect material for tying stop knots on monofilament and braid-ed main lines to maintain consistent accuracy when clipping up and casting to baited spots and features.
It works in exactly the same way as the popular pole elastics used for marker knots but ESP Marker Gum is much finer in diameter, nominally 0.45mm but un-der tension it will stretch and contract to around just 0.30mm.
This fine diameter produc-es tiny knots which simply fly through the rings without hindering distance.
Available in fluoro orange and yellow the different colours can be used on the same reel to mark dif-ferent spots. A simple 3 turn stop knot tightened down will grip the line securely and not move.
To remove the knot simply cut one of the tag ends flush with the knot and pull on the other tag end to release. Available on 5m spools (although by stretching the material down you end up with almost twice as much).
