This mat is flying off the shelf like Frisbee’s! The Dream Mat gold concentrator bowl mat insert increases your fine gold recovery and makes clean up times quicker and more efficient. Adding almost 100x mini cyclone cells that mimic the bowls base function, this upgrade to a tried and true favorite allows for the centrifugal bowl cleaner to run at a higher speed, reducing process time. Turbo charge your old bowl with Dream Mat magic! 4″ I.D. X 10.25″ O.D. Colors will vary. Note: If you glue the mat in the bowl use a non-permanent silicone that peels easily. Do not use super-glue or epoxy.
