Metal Detecting Online

You may not have a choice on what parts go into your older CZ20 if it ever needs repair. From what I understand the CZ21 parts will end up in or on your machine if you need a repair for leakage of the battery housing or the pin point button. They are the only parts that are now available to repair your old machine.
At the beach or in the water I always run auto tune. It gives you more depth and it gives you more width on all targets. What I mean is that it will broaden your swing by detecting items on a greater width than using disc. Try it you will see what I mean. when I get a hit then I will switch it to 0 of 1 to check the sound than up from there. I pretty much dig any good sound. I use the 8" coil and i get plenty of depth with it. What kind of chest harness are you using? The ones that Fisher have gives me a bad neck ache. I have a chest harness that is made for the CZ20 that is so awesome. Let me get you a picture of it.

These harnesses run $29.95 and they are the best. The bigger plate allows it to rest comfortably against your chest, they straps are made with expandable material and they are fully adjustable. I like a harnes that holds it tight to my chest.
Let me know what you think of this harness.
