Found these four seated half dimes 1839, 1851, 1857, 1871 and no dated Canadian 5cent piece all in one hole last time out with my X70. After 15 years or more of detecting these were my first seated coins. Needless to say I was happy. Also found a 1906 Indian and 4 wheaties that outing. I just purchased the 70 and I'm very happy with it so far. Seems to lockon to good targets very well. The seated coins were around 6in. deep. The Indian was around 5-6 in. deep and on edge with a good signal. Going back sunday to try this site out again. Love Them Xterra"s. HHJoe
