The Fisher CZ-3D Pro is tailor-made for finding more, higher-value, older coins. The CZ-3D features an Enhanced mode that specifically registers "good metals" (brass, bronze, copper, silver, & certain kinds of gold) with a higher tone. A fourth audio tone helps single out pull-tabs and foil so that you can avoid them and uncover gold jewelry instead.
The CZ-3D features four-tone audio ID, a categorized visual target ID meter, and one-touch pinpoint; an additional Salt mode eliminates interference from salt for superior beach performance.
