Just for what its worth I took the CTX out today to a place I had gone over with a DFX and Cortes. The targets were still there but this time with the CTX I noticed multiple targets on the screen as many have mentioned in other posts. When I saw 12-44 pop up on the screen among all the other id's I decided to check it out. Low and behold out came a clad dime and not a few inches away was a pop top! I would never waste my time before digging the other signals because the park is loaded, I mean loaded with pop tops and junk. CTX has two thumbs up in my book and I'm just getting started!
