My buddies and I use Ozark Dock Shooter rods in the 6ft length as well as the BnM Sharp Shooter in 6ft lengths.
We use the Crappie Pro Dock Shooter jigheads with the double collar in 1/24 & 1/32 oz weights and small (1.5in)
plastic bodies. Check out the numerous videos on "YouTube". Just type in the search box "dock shooting crappies"
You'll get a good number of returns. Oh and after you watch those videos, practice, practice, practice!!!!
