If the treasure was buried at 35 feet then after 75 years ethe electromagnetic expands lets say 15 feet outward in all directions therefore that treasure's electromagnetic can be detected above at 20 feet deep. But there is a high possibility of being offset to your target. Just keep in mind if there was an unwanted electromagnetic detections below then there was a gold cache inserted somewhere else. Your problem is to how to accurately pinpoint the object.
I feel pretty good about the target location because the smaller target was located using the same method (dowsing) and there have been so many perfect signs unearthed while digging to that target. At 43 ft there is this layer of large stones that you can really tell were placed there because they're interlocking. I say that because someone has chiseled out little indentations on the sides of the some of the stones so the other stones placed beside them can not be easily lifted out. You have to remove all the larger stones to be able to dislodge them. My feeling is the object is just below this layer... Take a look at the photo below, the target is marked. You can see its under the largest stone in the layer. That stone is perfectly flat on the exposed side of it.
I had thought that this smaller object had been buried deeper because it contains precious gemstones. The signs seem to indicate that it contains various types of precious stones. This was further verified using a frequency generator. Signal lines were created to the object using the frequencies I have for gold, diamond and emerald. While only the gold frequency created a line to the larger 8' object.
Question for you bro and btw I'm sorry for asking so many questions but your time is appreciated. At 12-14 ft depth I unearthed a perfect heart. It was laying face down. The measurements of the heart are roughly 6 x 7 inches. Nearby or within that same layer, which was very rich with markers, I found several arrow-like stones. Arrows and pointing hands. I have been wondering if this collection of stones was actually indicating that I should drift to the 8 ft object which is positioned 11 ft away. A treasure hunter once told me that the smaller the heart the closer I am to the object. So now that I'm already at 43 depth on this current target it seems that heart was actually for the other 8 ft object buried nearby. What are your thoughts?
