Not quite finished but test run anyway.
Hid some yellow in 10l bucket of gravel and recovered in sluice.

Very cool Thebaker, I like your idea. Sort of like how the old-timers washed the pay dirt through the punch plate on their cradles.
I made a rough ‘looker’ this morning. Just needs a grab handle (should be able to get one from Bunnings once lockdown is over)

Cheers,bit hard to bend metal until I worked out my metal break( gate on hinge)
. Sorry but what’s a rough finder?
Hahaha that’s some good improvisation. the ‘looker’ is just a circle of perspex glued onto the bottom of a piece of PVC pipe. It’s for checking out crevices underwater. Have heard that safety glass is a better idea though - it doesn’t scratch easily like perspex
I made these suction devices in lock down very easy with basic tools and crap lying round in my garage
@jabs Made something similar as a kayak bailer - shifted 20L/min.
Pingpong ball as a non return valve was the key. Would suck the change out of a Scotsmans pocket (I can say that as I’m of that ilk 
)

Go to the two dollar shop and buy there Magnifying glass about $5 and cut the black rim off it , think its about 100mm then get your 100mm P V C pipe and heat the PVC to it is soft and push the glass up about 20mm and run a bead of supper glue round it. Next drill a hole just under the glass at bottom to let the air out when under water. it will not scratch when on the bottom and the gold looks bigger , good luck.

Great idea, cheers!!!
I dont think a ping pong ball will hold up with gravels involved in a gold suction device. 
Besides…you generally want the material to fall back out into a pan, or not, if a retention chamber has been built into it.
