The Better Bobber is an easily adjustable 5/8" or 3/4" diameter float that can be used for bait fishing or as a fly fishing indicator. Just back off the nut to expose the slot in the male thread, slide in the fishing line or leader and then tighten the nut. To adjust the fishing depth, just loosen the nut slightly and pull on the line. There is no need to fully remove the nut once it is installed.
