Slip Bobber Rig
A float that slides freely on the line until it hits a bobber stop you set at any depth, with a bead between them and shot below. We ran it through the compatibility engine for 6 fish it is tied for: 5 of 6 clear every check. For Walleye in Weedy Lake the cheapest clean build is a #1 circle hook on 6 lb mono, 3/16 oz bullet + slip float, on a 6.6 ft M spinning rod. About $132.
tie it when
Fish suspended deeper than your rod is long: walleye on a reef top, crappie over brush in 15 feet. The stop winds onto the reel, so you cast short and fish deep.
skip it when
Fish feeding hard on the bottom, where the bait swings up off it as the float drifts, and anything past about 30 feet, where the stop takes forever to reach and the slack eats the hookset.
How to tie a slip bobber rig
- Tie the bobber stop on the mainline and slide it to the depth you want. Trim the tags so they wind through the guides.
- Thread the bead, then the slip float. The bead stops the stop pulling through the float.
- Pinch on shot below the float until only the tip stands proud. Under-shotted floats hide bites.
- Tie the hook on the end. Cast, let the line run through the float, and wait for it to stand up.
Solved for each fish
For every fish below, the solver searched the catalog at each water that fish is targeted in, under the rules in the next section, and kept the water where the slip bobber rig scores best: fewest engine errors, then fewest warnings, then cheapest. Open any row in the studio to see the same verdict.

What makes it a slip bobber rig
A named rig is a rule set, not a parts list. These are the rules we hand the solver. Every stage not listed (line test, hook size, rod, reel) is the solver's call, checked by the engine.
- float.terminalrequired: slip
- bead.terminalrequired
- weight.terminalrequired: split-shot or bullet or egg
- lure.platformnatural bait only, no lure
- swivel.terminalnone
The checks that decide it
The engine runs every check on every build. These are the ones that make or break a slip bobber rig, with how many of the 6 solved builds each one still flags.
Weight vs float lift0/6 flagged
More weight hanging under the float than it can lift, and it goes under and stays there. The engine errors.
Float under-shotted0/6 flagged
Under 0.35x of the float’s lift hanging below it, the float rides high and a fish has to drag it down. The engine warns.
Float past its working depth0/6 flagged
Past 30 ft even a slip float stops presenting a bait. The engine errors.
Float over a bottom feederflags Channel Catfish
Fish with a depth bias of 0.9 or more feed on the bottom, and a float hangs the bait above them. The engine warns.
Bead bore vs line0/6 flagged
Same 0.15 mm clearance for the bead. A bead that binds stops the rig sliding and saws the line at the bore edge.
Cast weight vs rod minimum0/6 flagged
Weight, bait and float together have to reach the bottom of the rod’s casting rating, or the blank never loads. The engine warns.

frequently asked
06What size hook for a slip bobber rig?
It depends on the fish, not the rig. Across the 6 fish the engine solved, the hook runs #10–3/0: #1 for Walleye, #8 for Crappie, #10 for Bluegill & Panfish, #8 for Rainbow Trout, #2 for Largemouth Bass, 3/0 for Channel Catfish. Each size sits inside that fish's window on our hook size chart.
How much weight on a slip bobber rig?
0.1875–0.25 oz in the builds we solved, set by the water: 0.1875 oz for Walleye in Weedy Lake, 0.1875 oz for Crappie in Farm Pond, 0.1875 oz for Bluegill & Panfish in Farm Pond, 0.1875 oz for Rainbow Trout in Farm Pond, 0.25 oz for Largemouth Bass in Farm Pond, 0.25 oz for Channel Catfish in Farm Pond. The engine sizes it against current (it asks for weight to hold bottom from a current rating of 0.5) and against the rod's casting window.
What line for a slip bobber rig?
6–17 lb mainline across the solved builds, with a leader on 2 of them. Braid ratings are compared to the rod by diameter, not printed test, because rod line ratings are written for mono.
What fish is a slip bobber rig for?
We solve it for Walleye, Crappie, Bluegill & Panfish, Rainbow Trout, Largemouth Bass and Channel Catfish. Channel Catfish (1 warning) still carries engine flags, listed on this page.
What knot do I tie a slip bobber rig with?
the Improved Clinch Knot (85% retained strength) and the Uni Knot (90% retained strength). Where a leader meets braid, use a line-to-line knot such as the double uni or the FG.
When should I not fish a slip bobber rig?
Fish feeding hard on the bottom, where the bait swings up off it as the float drifts, and anything past about 30 feet, where the stop takes forever to reach and the slack eats the hookset.
