Abstract
An adjustable buoyancy fishing bobber system for efficiently increasing or decreasing the buoyancy of a bobber to match the particular combined weight of the fishing line, lure and bait being currently utilized. The adjustable buoyancy fishing bobber system generally includes a casing including a first portion and a second portion, wherein the first portion extends from the second portion, wherein the casing includes a chamber formed within the first portion and the second portion. Adjusting the first portion with respect to the second portion adjusts a volume of air within the casing. A vent including a channel extends from the casing, wherein the channel extends through vent and fluidly connects to the chamber of the casing to allow the air from within the chamber to escape or enter within the chamber during adjusting.
