Power ratings denoted on the last 2 #'s of the rod model on a scale of "0" being lightest to "9" the heaviest.
"power" is how much pressure it takes to deflect a rod, the higher the number the stiffer the rod. *Note* Some manufactures ratings vary, and a 3 power magbass rod is different than a 3 power saltwater rod. So they are inclusive to their series.
On most long crappie rods Moderate action / Lt. power is the standard.
