Pop up rig

The distance that the bait is anchored off bottom is largely a matter of personal preference but 1 to 3 inches is common. If rig putty is used to hold the buoyant bait down then this can be trimmed to create a critically balanced bait which only just sinks. Critically balanced Carp baits will be lighter than free offerings and so as the Carp sucks the bait into its mouth it will shoot to the back aiding hooking.
