I've been searching and googling to find something out and haven't found the answer yet. In my searching I've discovered that there is a lot more to bobbers/floats than something to hang your bait from and tell you when you have a bite.
So, I decided to start this tread in the hopes it may become valuable information worthy of being a sticky.
Bobbers come is several shapes, styles, and sizes. Hopefully understanding the differences will result in eating more fish dinners

What I've been searching for is the answer to this;

I've seen references to using 1/8, 1/4 1/16 oz bobber. What does that mean?
Is it the amount of weight it takes to submerge the bobber or how much weight is needed to make it float properly?
