Sunday morning I went to the old park with very bad ground(fast grab @90). I almost every inch of this place over the last 7 years, but there was one section that is directly in front of the park offices that I only hunt on Sundays very early in the morning before the park even opens. I don't want anyone to see me digging plugs so I got there at 5:45 am and could hunt it until 7:30 am when the workers unlock the gates.The first pass I got a wheat penny and two clad coins. I found two more wheats and a couple more clad coins when I looked at my watch and it was just about time for the workers to come. I made one last pass and I got a nine inch deep signal that was had bouncing numbers. I decided to dig it and out pops a nickle that was very worn. I knew it was not a buffalo and probably a V nickle. I didn't even bother to clean it off until later in the morning while I took a break at a picnic table. I could see the liberty head and figured I would finish cleaning it at home to see if I could see a date. I left the park and headed to a football field that is behind a 90 year old school. The field is fenced so I hunted the grassy slopes that border the fence. I was finding coins every 20 feet with many being wheat pennies. I just thought a silver coin must be here and withing a couple of minutes I dug a 1952 Canadian dime. The power of positive thinking does work. I ended up with 8 wheat pennies, the silver dime, one buffalo nickle, and a couple of junk rings. I have found the de mode with the disc at 5 gives me my best depth on coins. I vary my sens between 65 and 80 and set it just below where it chatters. After digging the last 60 coins or so, I have pretty much got the coin readings and sounds dialed in. Foil and tabs jump all over the place and usually have a 90 reading in one or more of the sweeps. A coin will really lock on with the numbers. At first, I had a hard time ignoring these bouncing signals, but after digging a couple of hundred of them I finally got it through my thick skull what they were. I got that V nickle home and started cleaning it and got a date-1885 , which is a key date. It is pretty worn, but the date is good. I had a great day and most all of the coins were 8 plus inches deep. The big DD coil seems to work much better when the ground balance numbers are in the 80' and 90's, but that is to be expected. R.L.
