ABOUT YOUR DETECTOR
Your  CZ-3D  is  an  extremely  advanced  and  sophisticated 
instrument. It is maximized for a very specific function - finding 
&  properly  identifying  older  era  coins  at  older  sites.  Simply 
select  the  "enhance  mode"  with  the  utilization  of  the  "salt/
enhance" switch to find more rare coins!
The CZ-3D was designed to  find more good metals such as 
brass,  bronze,  copper,  silver,  and  certain  gold:  reporting  it 
as a high tone. In addition, a fourth tone has been added to 
distinguish  between  the  midtone  heard  on  round  &  square 
"pull tabs" and foil - this enhances your ability to recover gold 
jewelry. 
With  this  detector,  performance  and  ID  can  be  further 
enhanced by a slower coil sweep speed, more so than previous 
CZ models, especially in trashy areas.
Read this instruction manual thoroughly, practice often and

        Happy Hunting!
