I dont use floats, best idea i have had. instead of a float put a big weight and mark the spot where u drop the pot. Later when u come to get it have a small reef anchor or something along the lines. I use a large treble with some weight attached to it. throw it in the direction of your pot and drag it along the bottom untill u get either the pot or rope. only ever lost one pot this way because we forgot to mark where we dropped it.
