A&B Prospecting Supplies.

A&B Prospecting is the Southwest's largest gold prospecting and recreational mining supplier, with two locations in Mesa, Arizona. They stock metal detectors (Minelab, Garrett, Falcon), dredges (Keene, Proline), sluices, drywashers, and the full chain of equipment from concentrates to gold — relevant to overlanders who explore old claims and historic mining country.
