4 hour hunt today in the Pittsburgh North Side city park and scored again with the 10 X 12 SEF coil on the EX II. I love this coil. 1914 and 1916 Barber dimes, an 1875 seated that I dug to China to get (10 to 12 inches deep) and a 20, 23 , another 28 and 39 Mercs. Most silver in one day for me. Also found 9 wheaties, the oldest 1910 and the other 40's and 50's with 4 in one hole. Down about 6 inches that four in the one holer screamed silver, pegged top right but read 00-14 on the digital. Pinpointing with this coil is excellent. Trash separation is great, too, when I go into all metal. And typical of a large city park I dug up a modern spent bullet. It's big un at least 40mm. I wonder where the quarters and halves are?? My guess is that this place was probably hit by other MDers with less sophisticated equipment in the last 20 or 30 years and they scooped off all of the easy to find stuff.
