[QUOTE="mudgee hunter, post: 311549, member: 9124"] I use the same 25mm aluminum expanded cat walk mesh as wal, it can be hard to source. I have two of these running at two different heights of the base. No carprt, moss, rifflels etc. Just two traps!!!! Little fall is needed, and near idiot proof. I can empty, clean out and reassemble in under ten minutes. The first trap always holds 99% of the gold. Originally it was 1200mm long, and now its just 600mm long. I'd chop it down two 300mm!!! Except I need it to keep sturdy for the 600mm teared hopper. Am I loosing gold?.......... one always worries a tad about this. If I was only catching 70% of the gold in the first stage of my two traps, this would surely mean that in the secound trap, I would be catching 70% of the 30% I missed from the first trap!!! But I only ever get a spec in the 2nd trap. Open to discussion. Understand that the mesh works as a baffle, and not so much as a low pressure, vortex system. [/QUOTE]
