The Jackson Debu Nyoro Lure is an unpredictably moving, sinking stick bait. On a slow retrieve along the surface, the lure swims in an S-curve, but with a short and sharp jerk it'll dart off erratically like a fleeing baitfish. On a faster retrieve, the Debu Nyoro will dart around much more compared to a slower retrieve.
You can work these lures along the surface if you want, but they do sink so they can be worked up through any section of the water column.
