I went out with a friend of mine detecting today, and found an area where there was coins everywhere. I found $6.75 in the beginning of our hunt, and then it was like I was hunting over an electric transformer. My machine was going bonkers, popping and beeping every swing. I left my other coil at home, so I had to quit. When I got home I switched coils and she works great. I am going to go back to that site with my friend and we will start where we left off. Not really sure why there was so many coins in that area. I sure will miss that 5x8 coil this week.
