A number of prospectors up on the EF San Gabriel have glued low black matting to the front of their bazokas or LeTraps, and all of them like it. You can easily see if you are on gold or not. I even put black matting on the front of my CalSluice.
I don't know sluicing from shinola (desert here and all), and I'm not sure exactly where you are putting the matting, or how much turbulence it creates.... But.. Isn't the slick plate an important part of the Bazooka? Its there
for a reason, its LONG for a reason, and the bigger the Bazooka, and the bigger the scoop you can toss on there, the longer it is....
From my understanding, and I may be wrong, its happened before (every couple of minutes my whole life). A slick plate allows the material to sort itself out naturally in the water, heavies sinking, lights being displaced and
rising.. I'd think this is more important on a Bazooka than on a standard riffled sluice.. Seems to me from what I understand of how a Bazooka works, Materials sort, or start to sort themselves out on the slick plate, and
then the bottom of the material falls into the fluid bed, and then the lights blast straight through over the fluid bed... It seems a fluid bed doesn't work THAT fast and you only want the heaviest stuff to actually
get in there.
Seems to me if you mess with the stratification that occurs on the slick plate with some kind of matting, you could induce turbulence that could un-stratisfy(is that a word) the material and allow gold to blow right through.
Just my thoughts, I don't know if I'm right or not. Any thoughts? Is my thinking off? or am I just thinking too much?
