A float (sometimes also calle a bobber) is a device used in angling, which serves two purposes. It suspends the bait at a predetermined depth, and it serves as a bite indicator. Floats come in different sizes and shapes. The long, thin ones are very sensitive and are used for coarse fishing. There are many different types of float and all are used in different circumstances. A waggler which is a thin tube of plastic is the most common running line float on stillwaters and has the line threaded through an eye at the bottom, whereas an avon float has a largish oval shaped hollow area near the tp allowing it to be cast further because more shot should be added to the line to leave only the tip showing. An avon is used in slow flowing water
