I have a used Tek 2. I made a test garden. I placed the silver ring and quarter in two different plastic cups 6" deep. I placed a 5 cent and penny 6". I can pick up the 5 cent and the penny loud and clear. The other two I can't get a decent sound that I would dig. What is up with this? Can the cups actually make a difference? I need to be able to find silver for sure. Please give me some advice.
