The One, The Only, The Original, and still the Best Ice Fishing Bobber Invented since 1999 is the Ice Buster Bobber. There are a few Wannabes out there that don't add up to all the correct features the Ice Buster dishes out. Trim it down for the correct sensitivity so the fish won't feel any resistance. Easily snaps on and off the line. Never Freezes to your line because the base is below the waterline. Built with a straight slotted hole so there is no need for the plastic bead and your line will zip through while using only a stop knot. This bobber is glued together with a special waterproof glue so it won't fall apart. Other Imitators use a screw together base to attach foam that adds weight, falls apart and won't let you trim it down correctly. We have a solid piece of foam that doesn't have a hollow centre which lets water enter. Save the trimmings so you can use them for “Floater Foam” to pull behind a Lindy Rig or bottom bouncer in the Summer to keep bait afloat and in Strike Zone while Trolling!
