Blue Bowl Concentrator Kit for Gold Prospecting

The Blue Bowl Concentrator Kit is a water-powered fine gold recovery system for working down classified concentrates after a day of panning, sluicing, or dredging. Set up level and fed properly screened material, the Blue Bowl recovers gold as fine as talcum powder — the flour gold that rides out of a pan or washes over a sluice riffle. The kit pairs the bowl with a 750 gallon-per-hour 12-volt pump, flex hose, battery clips, a control valve, and how-to instructions, and the whole setup weighs about 5 pounds, so it packs into a crew cab or camp box without claiming real space. It suits weekend prospectors cleaning up a season's cons as well as club members who process bucket loads after every outing.

What's Included with the Blue Bowl Concentrator Kit

• Blue Bowl concentrator with center cone and threaded drain fitting
• 750 GPH 12-volt water pump
• Flex hose (color may vary)
• Control valve for adjusting water flow (color/style may vary)
• Battery clips for connecting the pump to a 12-volt battery
• Leveling legs
• How-to instructions

How the Blue Bowl Recovers Fine Gold

The Blue Bowl works on circular water flow instead of gravity riffles. The pump feeds water into the bowl through the side inlet, creating a steady vortex that carries lighter sands up and out over the rim while gold — far denser than the black sand around it — stays pinned at the bottom around the center cone. Because the separation happens in a controlled water column rather than a moving stream of gravel, the bowl holds onto gold particles too small and flat for a pan or sluice to catch reliably. Run the bowl from a bucket or tub and the pump recirculates the same water, so you can process concentrates at home, at camp, or on a tailgate — no creek required.

Classify First, Then Feed Slowly

Fine gold recovery in the Blue Bowl depends on two things the instructions walk you through: classification and level. Screen your concentrates to a consistent mesh size before feeding — mixed sizes disturb the water balance and let fine gold escape with the overflow. Then use the leveling legs to get the bowl dead level, dial the control valve until the flow just clears your material size, and feed a spoonful at a time. Worked this way, the bowl runs down a coffee can of black sand cons to a few spoonfuls of gold-rich material you can finish in a pan or snuffer bottle.

Why Prospectors Choose the Blue Bowl

• Recovers flour gold that pans and sluices lose: the vortex separation holds gold as fine as talcum powder, which is where a large share of the gold in many placer deposits actually sits.
• Runs anywhere you can fill a bucket: the 750 GPH 12-volt pump recirculates water from a tub with the included battery clips on any 12-volt battery, so cleanup happens at home instead of streamside at dusk.
• Rugged, simple construction: the molded bowl has no moving parts to wear out — the pump is the only powered component, and replacements are standard 12-volt bilge-style pumps.
• Light and packable: at about 5 pounds for the complete kit, it travels to claims and club outings without displacing detecting or dredging gear.
• Two-pack option for clubs and partners: choose the quantity option to get two complete kits and run twin bowls side by side through a shared batch of concentrates.
