Experimental Gravity Trap Concentrator Model 625

                                                  ( Bucket Lid not included)

Model 625 EGTC Experimental Gravity Trap Concentrator. (ie., Submersdible Sluice) 

    No need to build a miners dam or struggle to get the angle and water flow inside the sluice set right for maximum efficiency with the EGTC Gold Concentrator. 

      It's simple to use, secure the concentrator with cargo lashing to a rock, then stretch and shape this flex pipe so the material is being pumped "UP HILL" ! Or, buy the EGTC Bucket Lid and insert the EGTC through the window, snaps right in.   

    See the EGTC put to the test in at least 4 YouTube Video's that include Black Sand Concentrate clean outs.

   Pump a few cubic feet of the dredge material in and as it's crossing over the Deep-V surface, the heavier values will tend to settle as the the lighter over burden flushes out. Tested extensively, the EGTC is the only known prototype deep-v gravity concentrator that's gold recovery is over 99% efficient when used with a M625 Hand Dredge. The key is the intermittent pumping action and flushing out excess material accumulating in the concentrator during the hand dredging operation. 

          Here it is to answer the age old question. Does culvert piping really trap gold? This one does. Great way to conduct hit and run prospecting operations searching for black sand gold bearing deposits while hand dredging.
