I have performed successful air tests using Gold and Platinum Rings, but I have never been able to find any Gold or Platinum Rings on Land or at the Beach while using my CTX. I have only found 2 Silver Rings during the 4 years I have used my CTX. I have found 100's of Wheat Pennies, but only a very few Silver coins. My question is why am I more successful finding Gold & Silver Rings with other Minelab machines, such as the Explorer II and the GT than I am when I use the CTX? I have not dug everything, but I have often dug readings around where gold rings are supposed to register on my detector ID Screen, such as 12-01-12-33. The majority of the readings I have received while performing air tests include: 12-01, 12-03, 12-05, and 12-31 or 12-32. Some of the Gold Ring readings while performing air tests fluctuate all over the places especially when I go farther away from the coil. There is no way I have found to differentiate a pull tab from a gold ring. I normally use the CTX 6" Coil, which can detect rings as far away as 8" to 12" depending on the Caret when conducting air tests. Any suggestions would be greatly appreciated.
