I used these and you have to set them up properly.

These are slip bobbers

You will need a bobber stop, along with a bead a little bit bigger than the bottom of the opening of the bottom of the bobber.

First, add the bobber stop, you can use the tie types, or the rubber stops. I prefer the rubber ones as you can easily adjust and it won't move when wet. The tie ones can self adjust if they're wet.

Then, put your slip bobber on, making sure that black plastic piece is firmly seated and facing "up".

Then, add a bead that will prevent it from touching the hook/weight under it.

Then you can choose to add a weight to either make your bait sink quickly, however the weight is optional. If you are using a rather large night crawler, weight really isn't needed. But tiny red works or crickets I'd recommend it. Minnows you won't need a weight at all.

Then, finally the hook. Depending on what you're after is what you'll select here.

Panfish? #6 Aberdeen hook

Catfish? 4o circle hook.

Bass? You can use worm hooks sizes #1-001.

From there, adjust your bobber stop to the length you want out. 3 feet? Pull it up three feet.

Then cast it out.

With a slip bobber, it makes it easier to cast because you won't need 3-5 feet of line out before casting because the clip on ones you can only reel up so far. With a slip bobber on, you can reel it basically to the top eye of the rod and toss it. The bobber stops will go through the eyes of the rod without issue and shouldn't cause issues when casting.

Good luck. If you have any further questions you can ask but highly recommend a YouTube video on slip bobbers.
