How to fish a pencil float for bluegill: spool light line, attach a Gapen Pencil Float with Slip-N-Lock (sleeve partway for slip, all the way for fixed), keep the weight light enough that the slim stem stands but still tips on a soft take, and fish spikes, waxworms, or 1/32 oz jigs under docks, weed edges, and pond shelves on calm Midwest water. Live Pencil Float sizes: 5" and 7", $3.75. Catalog note: for trout, bluegill, perch, and crappie on spikes or light baits, the 5" or 7" Pencil Float is the size family Gapen points to for sensitivity.
Gapen Slip-N-Lock lets you attach or detach without cutting the line: insert line through the side slot, sleeve partway for slip, all the way for fixed. Pencil Float Features call out a fiberglass strong stem, orange & white antenna, yellow & black "bait lines," premium balsa body, clear protective coating, and ultra-sensitive bite detection. 1-year breakage guarantee under normal fishing - return to The Gapen Company, PO Box 385, State Center, IA 50247. The shop that packs and sells them sits in State Center, Iowa.
Social proof (honest): Pencil Float PDP shows 25 reviews, avg 4.5 of 5. On July 7, 2026, Emerson Goza (Rockford, IL) wrote these are the only floats he's found that stand up above 1/32 oz jigs. Daniel Magara (Jamestown, NY) called them great for panfish and calm water (Sep 30, 2025), then on Sep 7, 2025 noted a black stopper that was too large and slid off the float (2 of 5). L Hansen (Rockford, MI) found one too small for his use (May 25, 2025). Buy on how the slim float fishes light baits; if a stopper or stem fails under normal use within a year, return it to State Center and tell the shop what you received.
What is a pencil float - and why Gapen's slim profile?
A pencil float (pencil-style bobber) is a slim, elongated float with a thin stem. Less body volume means less resistance when a bluegill mouths a spike - the float tips or eases under instead of fighting the fish. Gapen's version adds Slip-N-Lock so the same float runs slip or fixed, plus a high-vis orange & white antenna and bait lines for reading depth and bait size at a glance.
Why this page beats a generic "use a pencil bobber" answer: live $3.75 price, exact 5" / 7" options on FLOAT-PENCIL, catalog light-bait guidance, and shop-level Slip-N-Lock steps - not a stock photo of a round plastic bobber.
How do you set up a Gapen Slip-N-Lock Pencil Float?
- Decide slip or fixed. Shallow docks and lily pads often fish fixed. Deeper shelves and brush that need a longer drop use slip with a stop.
- For slip: thread a float stop (and optional bead) onto the main line first.
- Open Slip-N-Lock: insert the line through the side slot of the locking device.
- Set mode: pull the sleeve slightly over the slot for slip, or all the way down for fixed.
- Add light weight and hook/jig below the float (see full rig).
- Set depth (slip): slide the stop so stop-to-hook equals the depth you want. Cast, watch the slim stem stand, adjust.
How do you build the full bluegill pencil-float rig?
Numbered shop sequence for Midwest bluegill on light baits:
- Main line: 2-6 lb mono (or light braid with a short fluoro leader). Match Gapen Float Stops line ranges (2-4 lb, 6-9 lb, 10-15 lb) to what you spool.
- Float stop (slip mode): Gapen Bobber / Float Stops (float-stops-bead.htm, $3.00) - silicone that sticks; wet the line above the stop to slide deeper without chewing the line.
- Bead (optional): small bead between stop and float so the stop doesn't jam the lock sleeve.
- Float: Gapen Pencil Float - start 5" for max sensitivity; step to 7" when you need a touch more cast or stem visibility. Price $3.75.
- Weight: the lightest shot or tiny bullet that cocks the float upright without burying it. Too much weight kills the pencil's whole reason for existing.
- Terminal: #8-#12 light-wire hook under a spike, waxworm, or piece of crawler, or a 1/32-1/16 oz jig with a tiny soft plastic or tipped bait. Emerson's review backs the 1/32 oz class under this float.
- Depth: start just above weeds or at the dock shade line; tweak 6-12" at a time.
- Cast and watch: soft pitches under trees and along weed edges. Watch the antenna tip - a lay-over, slow sink, or twitch is often the bite. Set light; don't horse thin wire.
Which Pencil Float size - 5" or 7"?
Live option group on the Pencil Float PDP ( FLOAT-PENCIL): 5" and 7" at $3.75.
| Pencil Float size | Live price | Start here when... |
|---|---|---|
| 5" | $3.75 | Calm ponds, spikes, max sensitivity, pressured bluegill |
| 7" | $3.75 | Slightly longer cast, a bit more stem to see, light wind on a small lake |
Shop rule: change weight before you blame the float. Change depth second. Change size third when cast distance or visibility demands the taller stem.
Pencil Float vs Crappie Float vs Bream Float - when to switch?
| Float | Live note (Sep 21, 2026) | Use when... | Tradeoff |
|---|---|---|---|
| Pencil Float (this CTA) | 5" / 7", $3.75 | Spikes & light baits; calm water; bluegill finesse | Less stable / less cast in wind than bigger bodies |
| Crappie Float | 5" / 7" / 9" / 12", from $3.50 | Broader panfish / crappie slip work; more body sizes | Rounder body = more resistance on tiny baits |
| Bream Float | Catalog 6" / 7" called out for panfish | Slightly larger panfish presentations | Not the spike/light-bait specialist the catalog assigns to Pencil |
Same Slip-N-Lock family. Keep this page's one buy click on the Pencil Float; Crappie / Bream are comparison links only. For full crappie slip-bobber depth work, see How to Fish a Slip Bobber for Crappie.
How do you fish a pencil float for bluegill on Midwest ponds and lakes?
- Ponds / small lakes: shade lines under docks, flooded brush, weed edges, and the first drop off a flat. Deadstick a spike first; then tiny lifts.
- Reservoirs / bigger lakes: calm mornings and evenings when wind isn't knocking the slim stem over. If whitecaps show, step up to a larger Crappie or Bream body - don't fight the pencil in rough water.
- Season cue (open water): spring and fall bluegill often suspend shallow to mid-depth on light baits; summer shade and deeper weed edges; this article is open-water pencil-float work, not ice.
- Presentation: keep the bait still more than you twitch. Bluegill inhale; the pencil's job is to show that inhale without fighting back.
When should you not use a Pencil Float?
- Wind and waves that lay the stem over: catalog stability favors larger float bodies - switch to a Crappie Float 7"-12" or Bream size that matches the day.
- Heavy baits / big minnows: the pencil is built for spikes and light baits. Overload it and you lose the tip signal that made you buy it.
- Hard current that planes the float: soft water and ponds first; river current often wants a different presentation.
- You already need a deep slip-crappie program: use the crappie slip-bobber how-to and a Crappie Float size ladder - link for depth, not a second CTA.
