The type of float is use occassionally is about 1" diameter and 8" long. The float has a hole through the center the length of the float. If you have never used one, I would suggest the BillyBob (I think) from wallyworld. My reason for this is it comes with the float stop (thread) and a threading wire to pull your line through. The setup is stopper tied on snugly but able to slide, float, then whatever type of sinker/hook/leader combination you prefer. The directions come with the float. This type is for suspended fish that way you can change your depth with ease.
The type I use mostly is a cigar shaped float (from wallyworld). This I attach just above my hook on my leader. Above that I use a barrel swivel, then sinker on main line. My leader length is anywhere from 1' -2'. What this accomplishes is sinker sets on bottem then bait w/float gets suppended 1'-2' off bottem. Hope this helps!

I got this setup from a post from Big George
