Fish confidently after dark with the SlipLock Lighted Slip Bobber from Clear Blue Waters, Inc. Its durable, high-buoyancy body and bright LED light provide excellent visibility for detecting subtle crappie, walleye, catfish, and bass strikes.
The versatile SlipLock design quickly converts between a fixed float for shallow water and a sliding slip bobber for deeper presentations.
Features:

• Bright, long-lasting LED light stick included
• Fixed-float and slip-bobber functionality
• Durable, high-buoyancy construction
• Made in the USA
• Large: Designed for heavier baits and larger gamefish
• Rigging Instructions
• Slide the upper and lower locking sleeves open.
• Place the fishing line into the bobbers center groove.
• Close both sleeves to secure the line.

For slip-bobber fishing, run the line freely through the center tube and use a bobber stop to set your desired depth.
