In 2005, Steve Arnold found a 1,430-pound meteor in Greensburg, Kansas using a homebrewed metal detector cobbled together with PVC pipes and duct tapes. It was worth more than $1 million:
FOR TWO WEEKS, STEVE ARNOLD TRUDGED through the dusty farmland of Kiowa County, Kansas, a 6-foot rope trailing over his shoulder. Tied to the end of the rope was a metal detector cobbled together from PVC pipe and duct tape. Back and forth Arnold paced, pulling the jury-rigged device across the dirt, hunting for meteorites. He had already found a few, but nothing bigger than 100 pounds or so. Mostly, he found horseshoes. And beer cans. Soon the farmers would want him off their land; planting season was coming. To speed things up, Arnold attached his contraption to a tractor. He was sure there was a bigger rock out there, just a few feet beneath the turf.
