I have owned a Fisher CZ-20 for around 6 years with a 10" coil. As most everyone knows, it recenty was upgraded to a CZ-21. I have done quite well with it if you read my signature.
I am trying to get my wife to try detecting and I didn't want her to use my other CZ-21 when it comes back from 1st Texas because it also has a 10" coil and she is quite small.
A friend found me another CZ-20 with an 8" coil for 350.00. I snatched it up!! It came in the mail yesterday and I went to my local park to try it. This park is right down the road from my house and I have hunted it to death. Very small. You can't even get a signal in the swim area. (well I couldn't!!)
I got out of my car and threw 85 cents in the water. I then got on my scuba gear and went in. This machine suprized the heck out of me. I was getting signals I never heard with my other unit. I dug 2 pull tab rings that were over 12" down. I was ALWAYS told the 10" loop was deeper. Now I am very confused as the subject goes. I was also picking up very small aluminum that my machine never hit on.
I plan on going back today. My idea is using the 8 inch coil and going over the swim area and marking any targets I get. Then going back with the 10" coil to make sure my observations are correct. I really know they are though. I am just confused as to why.
