The Korda White Bobbin indicators offer the ultimate in performance, customisation, functionality and look great. These bobbins have a two-sided design, one white plastic, and the other clear to show the super-bright new mini isotopes. Customisation with these bobbins is unrivalled; they have two interchangeable weights to alter the weight and tension applied to the line, a mechanism that runs through the centre for adjusting grip-strength of the line clip with a simple twist and there are two different length chains (6in abd 9in). The bobbins are supplied with bayonet-style hockey sticks that are fully compatible with the Stow range of indicators, so you can change between styles instantly, without having to unscrew your alarms.
