I took the CZ21 out for the first time today. I brought my Excal with me because I wasn't sure if I wanted to try to learn the new machine in a spot where gold seems to turn up every time I go there, but I went ahead and took the plunge. I ground balanced, set the Sensitvity to 10 (no chirping) and away I went. It took a few minutes to get used the the concentric coil as I am more used to the narraw strip of detection that comes with a DD coil like on my Excal II, but it came pretty easily. This spot has lots of iron so I set my Dics to 0 so I could hear where the iron was and work around it. I soon learned that I was getting some iron falsing so I dropped the Sensitivity down to 7 and things got a lot smoother. I really liked the overload feature. It kept me from digging several buried pop cans and I'm really glad I went with the 8-inch coil because it as easy to work around trash and iron. It was really helpful to not have the Excal iron null and resulting recovery delay in this iron-infested spot. Very nice machine!
