Expander pellets

Pumped, soft pellets that sink slowly. An F1 and skimmer hookbait, and a pole bait that matches a pellet feed.

What it is

Expanders are hard pellets you pump or soak until they are soft and slow-sinking. F1s love them. Skimmers love them. They let you fish a pellet that doesn't need a band and doesn't sit like a stone.

Prepare them so they sink, not float, unless you mean to fish them on the top. A syringe pump is worth having if you fish commercials a lot.

When to use it

F1s on pole or waggler. Skimmers. Days when hard banded pellets are ignored. Cold water, smaller expanders.

Seasonal strengths

Year-round on commercials. Especially useful in the cold and on pressured fish.

How to present it

Direct on a pole or waggler hook. Hair or band if they need to stay on. A small expander in a method mix as a change.

Hooking / hair-rigging / prep

Pump with a syringe or soak carefully. They should sink slowly. Too pumped and they mash on the strike.

Feeding

How much to feed

A small tub of prepared expanders is a hookbait session.

How often to feed

You're not feeding pints of expanders. Feed hard pellet, hook expander.

What to feed with it

Hard pellets, micros, maggots in the cold.

Best combinations

Expander on the hook over pellet feed. Expander and maggot. 4mm expander for F1s, 6mm if small fish mash 4mm.

Feeding notes

Hard pellets or micros as feed; expander on the hook is the usual pairing. You can feed expanders but it gets expensive.

Common mistakes

Floating expanders you thought you'd sunk. Mush. A size 10 through a 4mm pellet.

When to change bait

If they smash it, go harder or bigger. If they ignore it, maggot or corn.

Beginner tip

Pump 4–6mm expanders until they just sink. Size 16, pole or waggler, F1 lake.

Advanced tip

Colour and flavour are extra; sink rate is the whole trick. Match the fall to the depth they're sitting.
