Neil in West Jersey
New member
I had a bit of time after work today so I swung by an old site that I have not been back to for about a year or more. It is a lake that was dammed so that there is a 15 foot drop below the lake. I have found plenty of silver Barbers in the past and I was convinced I had gotten everything.
I thought I had my SEF in my Jeep and was disappointed that I was stuck using my D2. But my disappointment soon changed. As soon as I turned on the detector I got a silver dime 79-80 VDI, even before I ground balanced. It was reading 0 inches. I used my pinpointer and found the 1958 Rosie sitting just under the turf. I have a feeling that the lake spilled over during the recent floods here in South Jersey, taking the dime out of the lake and dumping it on the top of the hill.
After digging the Rosie, I tried ground balancing the detector, but I was still having a problem. The Signal with the RX Gain at 12 was around 35%, so I dropped it down to 10 and it balanced just fine. A little while later I started getting a lot of trash and iron signal at the low spot below the lake. I slowed down my sweep speed and lower the Recovery Delay to around 60. A little while longer and I got an iron signal with a bit of a sweet silver signal. The iron was there, but I was almost certain there was something with it, but it was hard to get the location. Eventually I was able to get a bouncy VDI in the high 80's and out came the Walker! I rescanned the hole and next to the half was an iron pick ax! Nice target separation with the D2!!! This thing was almost right up against the coin!
Since there was so much trash I decided to try single frequency 2.5KHz, which I have not really used at all. I hit a muddy wooded area on the other side of the lake where the minerals can be more concentrated and got a very deep signal with a bit of a chirp. It read 8.5 inches and after digging through some tough roots, I was rewarded with the 1956. The coating that is on the coin is the mineralization that makes it difficult for detectors to "see". The detector sometimes sees this as the ground. Filtration helps cut through it a bit. I was lucky to find it using 5Hz Band, but I think single frequency 2.5KHz helped.
So, I take back a bit of what I said about the D2 yesterday. Today I was able to ground balance it easily (at lower RX Gains), and I was able to get deep coins.
