Just wanted to give some feedback on the CTX 3030. I've taken it out on 2 hunts this week, other than playing around with it in my yard and figuring out some of the bells and whistles. The 1st hunt was a heavily beat down park that has produced some barbers, mercs, and a SLQ in the past. My hunting partner and I have spent a long time in this park with E-TRAC's. No new silvers were found but I did get a heart pendant that I am almost positive is white gold and old, not a new drop for sure. I picked this park especially since there is an area that has extreme litter, it used to be a city dump in the 1900-1920 era, there is lots of bottles and broken glass, scrap metal in the ground, it's also where I found my 1915 D barber quarter. The E-TRAC would just null out, not so with the CTX 3030. Yesterday I put it in the water at a public swimming area that gets hunted several times a week and produced a 10k gold ring. Too bad the stones were CZ but I looked it up and it retails for $150. Cha Ching, just paid for the headphones....The ring has been there for a while, four inches deep in hard pack clay. There was iron around it too, I am really beginning to see the advantages to the CTX 3030.
