For long range specialists, there is also a stainless Metal Head bobbin. This interchanges with coloured the Barrel Bobbins and 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. Kev Hewitt favours the Metal Head for most of his fishing and especially when zig fishing at range with a heavy lead where it comes into play for indicating drop backs. 

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.
