inspection mat which is best?

[Lefty2u]

I have been trying to figure out which mat is best to use as an inspection mat at
the beginning of my sluice box. Deep V or shallow V. I would like some opinions
and why.

Thanks

The way I look at it is ,it depends on the makeup of your material ! I bring several types of matting in my trailer when I went out traveling across several states just to get where I wanted to go dredging !

I have Shallow V first, it separates and catches gold. It can be quickly cleaned with a sucker bottle. Depending on water flow, Deep V doesn't separate out the black sands as well. But added below the regular V mat, it's the next step up in line.
The beginning of this video shows my set up, the second stage isn't a Deep V, but it's close.
