I watched and enjoyed your VID. IMO, and I think you covered it, the holes in your scoop were too small. I like just smaller than penny size. If something falls through that you can use the other scoop with smaller holes.
Thanks for posting.

Nice VID and cool finds. Thanks for sharing. GA Boy is right though....you need to ditch that
plastic scoop with the too-small holes. Get a nice half-inch wirecloth hand scoop or better still
a long-handeled model.
