We had close to 4 inches of rain the last few days, time to get out in the soup and see If I can dig more nickels with the O-8. I headed back to the park close to home where I have dug over 850 clad with the omega this spring. I decided to put on the 5" coil. and go over the heavy aluminum trash areas, where I used the5" & 10" coil. I started digging various signals from 40 to 70. I also dug the high tones of course. I dug the bouncy signals, and also the very tight numbers, to see if I could pick up more nickels. My ground reading was about 52, I usually ran the sensitivity at 90 or higher. I ended the day digging 40 al. pull tabs, mostly the square type.If I had just dug the tighter numbers, I would have dug alot less tabs. I also picked up 26 foil wads, those read just below 56. Some of the square tabs read 56-57, same where a nickel should read, a fair amount read in the low 60's. I found ONE lousy grungy nickel at 3-4 inches.It read in the low 60's. I then reburied it, and it read 42-44, and some times it would jump to 80. There was a fair amount of foil in the area. At this rate, In the heavy trash, I think I'll just crank up the disc, and forget about every thing below zincs. I did pull out another 70 clad coins with the 5" coil. How is your nickel count been? Im a bit disappointed with my nickel finds, I realize there are less nickels out there than most coins, but Im open to your thoughts. I pulled over 900 coins out of this park, and about 20 nickels.
