Gold Prospecting Equipment Maintenance

Prospecting gear lives a hard life: sand, grit, water, sun, and truck beds. The difference between equipment that lasts three seasons and equipment that lasts twenty is about fifteen minutes of care after each trip. Here's my end-of-day routine for every category of gear, learned across 22 years of wearing things out.

Gold Pans and Classifiers

The simplest gear still has failure modes:

Rinse and dry completely before storage — trapped grit scratches riffles, and scratches hold fine gold you'll never see again

Never leave plastic pans in a hot truck or in direct sun for days; UV makes them brittle and warps riffles

Check classifier mesh for tears and stretched spots — a torn screen lets oversize into your concentrate and skews everything downstream

Wash pans with plain water — soap residue changes surface tension and makes fine gold float out of your pan on the next trip

Sluice Boxes

Sluices collect damage in two places: matting and flares.

After Every Trip

Pull the matting and rinse it completely — dried clay cements into the vees and kills recovery

Rinse the box, dry it, and look down its length for dents that would disturb flow

Straighten small dings in aluminum flares immediately with a rubber mallet — they only get worse

Each Season

Replace matting that's gone stiff or shiny — worn matting can cost you 20% recovery and you'll never notice on the creek

Check every rivet and screw; vibration loosens them

Re-tension any turnbuckles and check leg hardware on stands

Metal Detectors

The most expensive item in your kit deserves the most care:

Coil covers are cheap; coils are not. Run a cover, and empty the sand out of it regularly — trapped mineralized sand under the cover can cause false signals

Never store with batteries installed in the off-season; leaks destroy control boxes

Wipe the shaft and clean the cams so height adjustments don't seize

Keep connectors dry and clean — dielectric grease on plug pins prevents corrosion in wet environments

Update firmware when the manufacturer releases it; detection improvements are free performance

Pumps and Highbankers

Water pumps die from neglect, not use:

Flush with clean water after every session — especially after silty or brackish water

Drain completely before freezing weather

Check impeller wear annually; a worn impeller moves less water and starves your sluice

Fuel-stabilize gas engines before storage; carburetor gum is the #1 winter killer

Grease fittings per the manual — sand plus water is a grinding compound

Snuffers, Vials, and Small Tools

Rinse snuffer bottles with clean water — black sand left inside abrades the valve

Dry crevice tools and magnets before storage; surface rust transfers stains to everything

Replace cracked vials before they fail in a pocket with a day's gold inside

The Off-Season Teardown

Once a year, give everything one deep service: full disassembly of the sluice, matting replacement as needed, pump service, detector battery-terminal cleaning, and an honest inventory of what needs replacing before spring. An hour in January saves a ruined first trip in April.
