The Jarvine Riffle is a SCREENED FLUID BED RIFFLE, or a baffle for your high banker.
It allows for the fine heavy's to slow down under the riffle on top of the miner's moss or deep V. Too stop your fine gold from blowing out over the mat. Plus, a great nugget catch that won't clog with junk.
This DREAM MAT original design was created to help prospectors have high bankers that are so far advance compared to old school tech, that it's like buying a spaceship!
Paul Jarvis (Master Highbanker Builder) has proved & tested the concept and adapted into his standard designs. As we say here at dream mat, RESULKTS RULE, the rest is just talk.
We hope as we find someone to mass produce this product will become more affordable. For now, we offer this product at cost. Soon other sizes will be available also.
16 Ga. 3/16" perforated sheet, w/ 5x 3/4" tall zigzag riffles.
