Different types of fishing floats.
A float, also called a bobber, is a device used in angling that 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 thin tube of plastic, called a "waggler", is the most common running line float on still waters, and has the line threaded through an eye at the bottom. An "avon" float has a largish oval shaped hollow area near the tip 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.
There are also floats that offer directional control. In a river you only need to cast one time if the current isn't too fast; after that, you can steer them left or right down stream, reaching areas you couldn't reach any other way. On a lake with no current you reel them 1/4 the speed you normally reel and they travel 4" for each 1" you reel. This reduces the amount of times you need to cast by 75%. They can be used to steer under docks or trees.
