Bobbers are great fishing tools. Not only do bobbers keep your line above water, they also bob up and down in the water when you've caught something, so you know when to reel it in. In this tutorial, you will learn how to attach and use a bobber. Bobbers, or floats, have buttons on top that can be depressed and attached to the line by a hook. In this video you will learn to adjust the depth when using a fishing bobber with help from a commercial fisherman.
