Been using a CTX 3030 a bit, but not as much as I like to, tried some of my old worked to death areas and getting different trash items that sound good. Did get a deeper and weaker signal at our local school and was figuring a deep wheat penny and showed 7 inches which I will say even those a inch down read 5 inches it seems. When dug this one was around 6-7 inches deep and turned out to be a 1972 penny, so I was not impressed with my find. On Sunday I went to another school as I felt there may be some new coins and maybe a old one too. After about a hour I had a new zinc penny and a clad dime and anything from pull tabs to pieces of tin cans. I was seeing how it worked better with experience. My setting were open screen in mode 2 and in mode one I made a screen I used on my E-Trac with the ferrous line at 22 and the conductivity line at 9 with the rest open I used when the iron hits were many. I used combined audio with +2 sensitivity and pitch hold as I am used to my Sovereigns. Now in the next hours I was picking up more clad and a copper memorial penny and still some trash yet. One signal I got was reading 11 to 12 ferrous and 36-38 conductivity and sounded a little deeper and was a bit jumpy so I tried to pinpoint it and went around it to see it seem to stay in the same spot and figured a deep older Wheaties from the teens or being the ground has been turned I was thinking maybe a rotted out zinc penny. Using my Uni Probe built into the headphones which to me is the best pin pointer for those that cant use the Sun Ray probes. I dug out my small plug 5 inches deep and really couldn't get a signal with the probe, or if there was it was real weak. Checked my pinpoint and it was right one, so back I went and dug deeper and got a signal, dug more and knew I was close as my Uni Probe started squealing when you get real close to the target. Was down around 9 inches and seen it was a penny, but very corroded and was able to see One Cent on the back and seem the wreath, so I knew it was my first IH with the CTX. Got it home and used my hot peroxide and a small brass brush and was able to get the date a 1893 IH that is well detailed, but very corroded up.Now that did impress me as there has been older coins found at this school, but they are far and few as one local never got any old coins out of there this year, but last year got a Wheaties.
My sensitivity in auto plus 2 was 19 and the green number was 24 and after the first hour I ground balanced the CTX and don't know if that helped or not as i was running ferrous coin.
Just got to get out more to learn this detector from experience with this detector.
