The Arbogast Bobber Stop is the must-have accessory for every panfish angler. Once the angler locates the depth if their 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 their hook then recast to their favorite fishing spot. Once the spring reaches the red bead, it will stop at the preset depth, keeping the bait at that depth every time. The angler can adjust the Bobber Stop's depth setting with the flick of their finger. Easy to follow instructions of quick rigging are found on the back of the package. 5 stops and 5 beads in a recloseable package.
