Gavzilla-i spent 7 months on the arrow,only returning to jafaland in may this year.
I use a caledonian-no matting-good
Homemade sluice from wood with ripples and astro turf-not so good ,and ripples and vynyl loop matting-to dam good.
Homemade stainless sluice-ripples and vynyl loop matting,too dam good
Another homemade sluice with ripples and STD FLOOR CARPET FROM THE OLD ASSAY OFFICE,almost perfect,and tgen some ripple carpet from mitre 10(dam near the same as keene green)-perfect.
I eventually added a plastic soil classifier from mitre10-i posted a picture on a thread here,diy sluice i think it was called.
No losses,no huge amounts of black sand-in fact it was 1/4 the volume of vynyl loop matting.
I also saw 6 a52’s in action-all of them had keene green in and they were outperforming everything else-especially your dream mat.
One guy was a local at Q/T and i personally saw him get 1 ounce iver a few months of 1 day a week with that keene greene.
