Thanks Swampstomper Al ,
I appreciate your reply , I will be taking in my own water so will this make a Henry Poop tube feasible in my case . I'm sure I can water down the clay with a drill and paint stirrer before the trommel , Jenny will spend some time on this while I am detecting . Will always be close by if she needs assistance . I'm going to pan a bucket at home this weekend to see the potential .
Cheers
