Fine Gold Cleanup Station

I made this simple vortex bowl for separating the fine gold out of the black sand once I start prospecting this summer. I intend to get the black sand out of the sluice I will be running in the river at the spot I am prospecting then bring it home in buckets and run it through another finer sluice and then this vortex bowl. I made the bowl out of a small bucket and some scrap tubing that was laying around. I still need to add a cone around the exit tube so it isn't straight up and down. The bowl simply hooks up to a garden hose but uses so much water I think I will make it recirculating. I have tested it and it does work well as far as the light stuff dissipating quickly but cant do any prospecting to fully test it as everything is frozen and covered in snow!!! I will do a video at the end of the week to show it running but only have small bit of mud I found in a snowbank to run through it:) Lol Maybe I will get lucky and the snowplow was spreading gold instead of salt!! Anyway I hope you like it and if you check back soon there will be a video!! Thanks for reading!! Please if you have any suggestions or advice comment or pm me I am a total newbie to prospecting and need all the help I can get!! Now I have a question for anyone who knows these things: Will the top off a small traffic cone be any good for the cone around the exit tube?? Please help!!  P.S Don't mind the floral mat in the sluice!! It was the only indoor outdoor carpet I had !! https://www.youtube.com/watch?v=umYDz95034I  That is the link to the video I need to shorten the exit tube alot before I put the cone on too!!
