Fine tuning your Trommel and determining what water pressure, feed rate and angle works best for the material you are processing will happen only with testing the material you want to run. Start with a shovel full in the hopper with lead shot, bb’s,etc. and let it run, determine that you have caught your heavies in the gold pan. If you overload the machine you will end up with a lot of light material in the gold pan, Slow the feed rate and/or increase angle of the machine. Remember the Reverse Helix Barrel works on the same principle as a gold spiral wheel, it needs time to wash properly and overloading it will not give it time to settle the heavies.

IF YOU FIND GOLD IN THE BACK-UP SLUICE BOX (you are not running it properly) If you are recirculating your water, Fine Gold can float when the tension of the water becomes very high from being muddy, its best to filter the water and keep it as clean as possible. Also good idea to check the spray bar/screening barrel from time to time to make sure it is not getting clogged up with debris (leafs,roots,etc) IMPORTANT: make sure to never clog up the Spray Bar or Classifying Screen as this will effect the process of Gold Recovery.
