So, my current mission to test all the metal detectors in my stable against a deep silver dime in my test garden continues. Now…remember…variables is a key word here. Meaning, time constraints won’t let me test all of the machines on the same day…and I have witnessed numerous times that the exact same metal detector can NOT get the dime one day and then (with identical settings) can get it the next. The variables I’m talking about are ground moisture, “invisible” RF interference, etc….heck, it could even be moon phases, gov’t conspiracies and UFO’s for all I know.
So, this take this test for what it is…different detectors on the same targets but on different days. Up to bat today is the venerable Fisher CZ3D. The original CZ design is dual frequency and originally the brain child of Dave Johnson. It has had many iterations since with the last being the 3D. This is a design that goes back to the late 80’s/early 90’s! Amazing that it still holds it own against the modern crop of metal detectors.
