Hello Tom:
Thanks for the info on the CZ-21. I will most likely buy a 21 in the coming weeks.
I've been betecting for about 35 years or so. Since my retirement from the Wilmington, DE Fire Department in 2000, I spend most of my summer in Fenwick Island, DE hunting the beaches of Delaware and Maryland. Most summers I find over 50 rings and other assorted jewelry, $600 to $800 in change, and hundreds of other items.
I've owned several make detectors over the years but find the CZ-20 works best in this area. I'm getting 18+ inches in dry sand and a bit less in the water. Because I hunt 6 to 8 hourd a day my detectors tend to wear out or need tooning every year or so. I really dont need 4 detectors so my oldest CZ-20 may head for the happy hunting grounds.
Thanks again for answering my questions, and good luck on your trip.
Bob Hayes
