Didn't realize we could post videos here or I would have shared this a couple weeks ago. So.. this has a hundred different names I'm sure, but up here we call it the "pits rig" since we use it to fish deep super clear water sand pits. It works anywhere there's clear water though, like here for these pre-spawn bluegills up shallow in super clear water. Surprisingly the yellow line actually didn't hurt as far as I could tell, usually they shy away if you dont use clear line in these situations in my experience.

What you didnt see in the video is that I tried them with a normal split shot rig, a small jig, and a float rig and they ran away from it every time. 100+ big bluegills all in schools up shallow and they would all take off the opposite direction.

Sorry about the long video, I know they are supposed to be short but its hard to get the fish catches in and still have it be short!
