What it is
Pellet on the pole is how a lot of people actually catch F1s. Pump expanders so they sink slowly, or band a hard 4–6mm. Pot micros over a plumbed line. Depth is the adjustment: deck, a few inches off, or shallow when they come up.
Use the fishery's own pellet if they sell one. Mixing the wrong pellet on a picky water is a blank with extra steps.
