For long range specialists, a stainless Metal Head bobbin that interchanges with the ESP Barrel Bobbins.

The head itself weighs 15g and with the stainless chain connector and add-on weight incorporated, can be increased to 21g. This extra weight improves bite indication at range on a tight line and especially in windy conditions. 

The interchangeable line clips simply allow the bobbin to be fished running on the line with the ball clips or gripping the line 'Elstow style' with the grip clips. The 3" ball chain is best suited to this setup, with the bobbin fished on a short drop near the bite alarm.
