Bobbers

Bobber Indicators unscrew and screw onto your leader. They are secure, float high and are highly visible. If you want to adjust the height of the float, just let a little water in.

Available in 2 sizes:

Large (1 inch)
Small (3/4 inch)

Pack of 5 including one "glow in the dark"

Unfortunately the larger size impacts on the postage cost because they have to go as a packet and not a large letter. Hence they are a little more expensive. Blame the post office!
