this is what i do to get crappies.lets take the hudson river[tons of crappies]go to the back waters by you
fish the north end of the back waters[tide makes a differance]crappies will come up to hit a bait,but most times
will not go down,so start fishing about 1ft under the water,what i use is a brown/orange 1,1/2 in tube,on a bobber
tube is on a 1/16oz jig head,cast out,let set till ripples on water stop then give a small crank with reel to make
bobber move then let it set,time to let it set.???up to you,do this for 20 to 30mins, then move the tube down
to 2ft and do the same,each day is differant,but i have hooked as many as a '100' crappies in one day[most went back]
hope this helps
