Hello Coinspader, give it some time your settings with be fine but keep your sensitivity 3-4 . Ground balance is a must for the best performance. When you get a good target sound in two directions, then turn 90 degrees , if you still have good sounds ...... dig it. But here’s the best tip ....... when you pinpoint your target, good targets will be a very tight audio blip and most rusty iron targets will have elongated lengthy pinpoints. Also when an iffy signal occurs the pinpoint my have two beeps, meaning probably a good target co-located (masked) with iron. With the volume at 5 or less you will have modulated audio (deep audio-soft but repeatable), how I run it . Volume above 5 makes all targets sound the same.... shallow or deep will be loud. My CZ5 has been my go to machine for 24 years now and still outperforms lots of high end detectors. Any other questions, just ask and I will try to help out . HH Tony
