I have #4, 30, 50, and 100 mesh, looking for something between 4 and 30 and it looks like logical choices are 12 or 20. Any suggestions? This would be a full sized screen for dry material. Thanks in advance.

I preach "times 2" 4x2=8 mesh 8x2=16 16x2=32 so not to exceed I use 30 mesh. so the answer I would have is 8 and 16. By not going over 2 times, the smallest piece of gold in that batch will out-weigh the largest piece of garbage.
Mike,
Thanks for the quick reply.
A bit more info, I am panning down to +30, then running -30, -50 and -100 material thru a blue bowl. I presently am using a kitchen strainer, which I estimate to be about 16 mesh in the gap, but I wanted something 5 gallon sized to go with my other classifiers.
If I followed you correctly you advised that starting with a 4, the next step should be 8, then 16, then 32/30, then 60 then 100....roughly, right? Anything larger than 4 I am just rinsing the dust/dirt off and running a MD over in case I have a piece of quartz or something with some entrapped gold. Am I on the right track?
I am a bit of a greenhorn to this despite my 71 years of age. Having fun in my "golden" years though.
