Took the Explorer and the Omega out today to compare signals. I was heading to a park that I had detected before and found some wheat pennies but no silver. On the way I drove by another park that I had seen before but never detected. It is real small, maybe 75 yards by 75 yards but it looked good so today I stopped. I took out the explorer first and started marking signals that I thought were coins with golf tees. I marked maybe 8 targets and then put the explorer away and took out the Omega. On the third signal I got a solid dime reading. I knew it was shallow so I just used my pinpointer to locate it. Sure enough it was probably an inch down. Took a screwdriver that I carry with me and just used that to pop it out of the ground. I was shocked when it came out. Out of the older coins I have found this was the oldest and the shallowest. Dont know how it survived so long without anyone else finding it.......Ok so I actually found the signal with the explorer but was using the Omega when I dug it.....That's why I said almost......;o)
