We have been having some incredible weather here in NE Ohio and I have spent the mornings hunting with the Xterra 70. Good finds just keep coming from spots I have been hunting for years. This detector is as good as any I have ever had. Yesterday, I found two mercury dimes(1941 and 1917) , a 1943 quarter, and 5 wheats. Today I found 4 wheats, one merc(1943), and a 1909 V nickle. All the coins today came from 8 plus inches. I have 12 silver coins, 2 buffalo nickles, 2 V nickles, 2 war nickles, and 25 wheats in the last week or so. These are not from new spots and considering that, this detector is truely making old spots new again. I used the 10.5 7.5khz DD coil to make all these finds and yes, this coil is the real deal in my humble opinion!
