Product Description:
THE D.A.M. Gravity CONCENTRATOR BOWL or "The Blue Bowl" as it is commonly known will quickly recover your fine gold with only the water from a garden hose, or it can be rigged to recirculate with just a 12 volt pump (optional) and a 5 gallon bucket (not included).

Panning fine gold and black sand concentrates by hand is very difficult and can be incredibly tedious. The Blue Bowl can recover Gold as fine as talcum powder when setup and run properly.

This is the famous plastic blue bowl gravity concentrator designed to work forever with no moving parts. Comes with water flow control valve.

It is strongly recommended to wet the concentrates prior to adding them to the Bowl.

Recommended items for an optimal re-circulating fine gold recovery system:

Blue Bowl

Leg levelers (optional set of 3 available below)

12V pump (pre-plumbed)

3 ½ -5-gallon plastic pail

18-gallon plastic tub

Wetting agent (Jet Dry, etc.)

Enough treated water to fill the Bowl, pail, and tub to proper levels

12V battery, or other suitable 12V DC power source (a 12V, 6-amp battery charger will work in a pinch)

TIP: Before cleaning out the BlueBowl, shut off the water supply and allow the water to settle down. The Gold can then be removed with a sniffer bottle.

Customer comment: I use a Blue Bowl to recover the fine gold with exceptional recovery rates. The bowl recovers even super fine gold if you exercise some restraint and run the water flow slightly lower and feed the bowl a bit more slowly after classifying your concentrates. Then try using a magnet on them. I do this to my buddy's concentrates (which he thinks have no gold left) and usually pull out another pennyweight or more of super fine gold. SHHHH don't tell him!

Order your blue bowl fine gold recovery tool early as we sell out often. Allow approx. 1-2 weeks shipping.

Also available - a set of 3 leg levelers that make adjusting and balancing much easier. Complete Blue Bowl kit: pump motor, hose, and battery connectors. Choose above.

How to use the optional (but recommended) set of 3 leg levelers ($18.95 per set)

You can raise or lower the bowl by turning the large disc clockwise or counterclockwise while attached to the bucket. The flange will hold the leveler in place as the disc is moved in either direction. Add these to your blue-bowl concentrator order below.
