Before you buy an automatic panner --
Check out these points!
* Does the bowl vibrate?
Vibration naturally causes heavier material to settle into the grooves
* Are the riffles undercut?
This is great for trapping gold and allowing lighter materials to wash away
* How big or far do the lead in riffles reach out of the bottom of the bowl?
Smaller riffles sometimes don't have a chance to grab gold before it washes out
* Is the bowl one, solid piece?
Ridges or tabs disrupt grooves and gold recovery
* How sturdy is the bowl?
Extreme temperature and UV light can warp or deteriorate a bowl
* Is the center tube stainless steel?
This allows the bowl to be used for amalgamation of concentrates
