Have been metal detecting for close to 35 years, and have never owned a Fisher metal detector. That changed today when I purchased a CZ7a. Was always impressed with the good balance of the Whites detectors, even though they were fairly heavy. I was amazed at how well balanced this detector is. Am also amazed at how well it air tests, if the rain ever stops here in SW Washington, and it may tomorrow, I will be going over some sites I have worked hard in the past. Will post the results as soon as I have any.
