Lots of brush in the lakes I fish and the weight on bottom (bell sinker) acts as a "feeler" for me. Also it will gradually pull down a pole letting you know there's brush there so by gentley lifting and lowering the pole you get the weight free without breaking off. Lots of guys will add two hooks above the weight but I've found out that if theyre biting one hook does as good as two, and costs you WAY LESS in minners.
