The Arbogast Bobber Stop is the must-have accessory for every panfish angler. Once the angler locates the depth of the fish, they simply 'mark' the spot on their line by installing the Bobber Stop spring. This will allow them to reel their line in completely, bait the hook then recast to that special fishing spot. Once the spring reaches the red bead, it will stop at the preset depth, keeping the bait at the correct depth every time. The angler can adjust the depth setting of the Bobber Stop with the flick of their finger.
