Hi Guys,
Has anybody here have experience using gold hog mats on fly**** gold?
Talking beach sand down to 20-50 micron and up.
Wading thru youtube clips gets a bit wearing listening to him droning on.

Waste of time TBH. They make OK clean up sluices for your concentrates but in any operation that has a large water column depth they are useless ie dredges or screens.
Its all just a marketing ploy to pay for overpriced pieces of rubber.
The issue is once you start having a deep fast water column in your sluice the vortexes created by the matting collapse which results in loss of fine gold. The same principal also applies to small raised expanded metal which works best in slower water velocities ie in a undersluice (in a dredge) but not so well in the main flow of the box.

I agree, ran them in a six dredge, loved the clean up being simple, but then did a test and then added a keen sluice box on the end. I found that 20% fines was going down the toilet. They probably work ok with low water flows at moderate speeds but not in a dredge.
