My prospecting buddy has this spiral wheel - and I must say I am not impressed. There is a center removable cap for the super cons... I do like the small battery built in and with the hand crank it is legal to use most places... but still not something I would invest in.
I find a finish sluice, fluid bed concentrator or the gold cube to all be better investments. As far as the Miller table goes - they are great but NOT for concentrating! Use one of the before mentioned ways to get you 'super' cons - then classify them (if not already) and run on the Miller table for clean gold. The backside of the
Hobbico and Staples self healing matts work very well for a Miller table surface by the way.
For a pre-fab finish sluice the
bucket sluice concentrator is very good bang for buck! Thanks Dale!
For a pre-fab fluid bed the
quicksand concentrator is very good bang for buck! Thanks Rick!
The
gold cube... well is the amazing, super fast
gold cube! Thanks Mike and Red!
If you want to build your own finish sluice or increase fine gold recovery rates in your stream sluice, the new
Gold Hog AR matting should be available this month! Thanks GGG!
If you want to build your
own fluid bed The Gold Hog guy GGG has a nice
starter video. Thanks again GGG!
You want to build your own Gold Cube? Watch Mikes youtube channel... thanks Mike!
Don't under estimate the 'boil boxes' between each tray... part of the secret... ssshh - not just active vortex matting...
