If you have a boat, just get a 12 volt rough service bulb from Walmart, Stick it in an aluminum shrouded clamp light, take a cheap extension cord (or old one) and cut the plug end off of it and attach a couple of clamps for clamping to battery terminals. The plug on the cord will have one wide blade and one narrow blade. The wide bladed wire will be your negative connection. Now head up a creek at night with a bucket of minnows and use a bobber and stick your hook about 12" -18" below is using a split shot for a sinker. Ease down the creek bank as quietly as you can with your TM and drop your bait next to every little stick up and brush you come across. Try to drop it into every nook and cranny you find in bigger brush. You should be able to come across some nice Crappie using this method.

If you don't have a boat, then find a good spot on the bank (preferably a creek) and set out serveral rods from 12" deep to 4' deep and don't forget your lawn chairs. If possible, build a campfire and enjoy the evening.
