Today I had one hour to MD so I went to a familiar site that I had thought to be almost DONE. I set the recovery to 45 and slowed my sweep speed to a crawl . the results were amazing. 8 Wheat's 3 Mercuries 1 barber and an Indian.I was working in an iron field (probably a burn site) .The hour stretched into two and I would still be there but for low batteries.(should always keep them charged I know but!!!!!!!!!) How SHORT can the V still be effective in real nasty Iron? Rob? Larry? Here are the pics The barber at the top is from a few days ago same site Bill
