I am fascinated watching videos of crappie hitting jigs. There are several on youtube but
this one is on a Nebraska fishing blog. The video was taken on Kirwin Reservoir in Kansas
in 2007. Cameras have gotten better since then but you still have to be in pretty clear
water to get video worth watching.

Amazing how long and hard most of the crappie study the jig before biting. (dual jigs in this case).
So many times all they do is nip at it gently and swim off. A few of the hits are hard where
they just swim in and take it. Good long video that you might enjoy.
