If you want to hang heavy nymphs there is no better way to do it. You can simply loosen the nut, place the line around under the nut and tighten it. An O-ring will grip the line and you are all set. It is so simple to add, move or remove the Bobber without causing any damage to your tippet.
Changing depth is fast and simple and takes just a few seconds. Only available in 3/4 inch, with five colours per packet.
