The float has sat motionless on the black water for twenty minutes, then it twitches once and slides under in a slow, almost polite glide. No frantic dancing, no alarm bells. Just gone. That single moment decides whether you've got a zander on the line tonight, or just another story about the bait that got away. Float-fished dead bait is one of the oldest zander tactics there is, and it still outfishes half the stuff invented since. But only if you get the details right.
Why Dead Bait Under a Float Still Works
In autumn, when zander go into their pre-winter feeding frenzy, they're not just actively hunting open water anymore. A lot of their energy comes from spots where minimal effort brings maximum reward. A dead baitfish drifting gently in the current shadow of a groyne or along a drop-off is an offer a zander rarely turns down. It gives off the faint scent of slightly decaying tissue — which is only amplified in cool autumn water — and it moves so subtly that the zander reads it as an injured, dazed fish. That's exactly the prey profile a zander is wired for. No lure can perfectly replicate that combination of scent and stillness, which is why the old float rig still earns its spot in my tackle box in 2026.
Getting the Baitfish Size Right
The most common mistake I see on canals and rivers is a baitfish that's way too big. A lot of anglers assume bigger bait means bigger fish, but with zander that's only partly true. On the float, I fish almost exclusively with baitfish between 8 and 14 centimetres. A small roach or bleak in that size range gets taken crossways in the mouth and sucked in completely before the zander even thinks about turning away. Bigger baitfish over 15 centimetres often get grabbed only by the head or tail, get played with for a while, and get spat back out at the first sign of resistance. On pressured waters, where the fish have gotten cagier, I land noticeably more consistently with the smaller bait than with the bigger one that looks better on paper for pike or catfish. For genuinely big zander over 90 centimetres, the baitfish can nudge past the 14-centimetre mark, but anything beyond that brings more missed takes than extra pounds on the scale, in my experience.
The Float and Its Capacity
Just as important as baitfish size is matching the float correctly. This is where the second big mistake happens constantly: the float is too small for the combined weight of baitfish, lead rig, and leader, so the tip either sinks under normal ripple or tips over at the slightest gust of wind. For a 10-centimetre baitfish with a matching 10–15 gram sliding lead rig, I fish a sectional float rated for 4–6 grams. With baitfish around 14 centimetres and correspondingly more lead, roughly 20 grams, I move up to a float rated for 8–10 grams. The basic rule I give every newcomer on the bank is this: the float should be trimmed so that only the top 2–3 centimetres of the tip show above the water. Anything that sticks out further adds resistance to the take, and the zander feels that instantly and spits the bait before you can even react. A float that's underweighted, on the other hand, sits unstable in the water and flags constant false bites in chop or light current that are really just the float bobbing on its own.
For the rig itself I use a sliding lead system on the float with a short leader of braided wire trace, about 25 to 30 centimetres, so the zander can't bite through the line. The baitfish is mounted on a double-hook rig — one hook through the lip or gills at the front, the second placed laterally through the back. That keeps the baitfish stable in position and stops it from spinning on itself, which happens fast in light current and looks unnatural the moment it does.
The Strike After the Take
Now comes the part where most bites get lost — not at the bait, not at the float, but in the angler's head. When the float goes under, almost everyone's first instinct is to strike immediately. With dead bait on the float, that's almost always the wrong moment. At that instant, the zander usually has the baitfish crossways in its mouth or has only just grabbed it, and striking too early simply pulls the bait straight back out. Once the float has gone completely under, I wait another two to three seconds, keeping the line taut but without applying any pressure. Only once I feel the line continuing to move steadily — meaning the zander is already turning away with the baitfish in its mouth — do I strike. And then it's decisive: one firm, sweeping motion of the rod up and back, not hesitant, not rushed.
That two-to-three-second wait feels like an eternity on the bank, especially when you know there's a fish on the other end of the line right now. But that patience is exactly what separates a zander hooked cleanly in the corner of the mouth from a fish that tests the bait a second time before bolting for good. If the float just twitches and pops back up, that's usually a zander that only nudged the bait. No strike needed here — just patience and a calm hand on the rod, because the next, more committed bite often comes within the following minutes.
Fishing the Rig on the Water
This technique works best in spots with little to moderate current — eddies behind groynes, harbour basins, or calm canal stretches — where the float sits stable and isn't constantly dragged off by the flow. I lay the rod flat on a rod rest with the drag open or only barely tightened, so a taking zander can pull line without feeling resistance right away. Running two or three of these rigs at once across different spots noticeably improves your odds, since you cover different depths and structures simultaneously while you might still be actively working a spinning rod yourself.
The Key Takeaways
A smaller baitfish between 8 and 14 centimetres almost always brings more and cleaner bites on the float than a big chunk. The float has to be matched exactly to the total weight of the rig so that only a few centimetres of the tip show above the water, letting you clearly tell real bites from chop. And the decisive mistake that loses most zander is striking too early. Wait until the line keeps moving after the float goes under, then strike decisively. Put these three things together, and the old dead-bait float rig is still, even today, one of the most reliable zander methods I know.
