Here's the GoPro Down Hole Perspective of some Big Rainbow Trout Reacting to the Dead stick presentation of a tungsten jig and half meal worm.  If you fish for trout and still haven't tried a dead stick presentation with a micro jig then you are truly missing out.  Some of the biggest fish on some of the most off days will still hit this set up.  Check out this underwater video footage and I hope your eyes are opened to trout behavior under ice and the usefulness of a dead stick / auto fisherman.
