Yes you use your sucker bottle to suck up the gold off the mat. Just like in the video rob made, the lighter material flows off the table and the gold plants itself on the mat. Now in Robs video I see he is using cons with alot of black sands from dredging he said. Now I dont have a dredge so the material I am running on it has black sand but also alot of other sands and little pebbles. And all that lighter material runs right off leaving the black sands and gold, the black sands follow soon after leaving only the gold. I was thinking about purchasing a blue bowl, but once I saw one of Travis's "black magic" tables I wanted that instead. What I liked about it was you dont have to screen down as much as the blue bowl(from what I have been read and been told about the blue bowl). Brian
