7 When your CZ-3D is properly “ground balanced,” it will have only a minimu m respons e to ground mineral ization. Precise adjustment of the ground control is critical. The higher the degree of ground mineralization or sensitivity setting, the more critical it is. Once you adjust it in either the Autotune mode or Target ID mode, you can switch ...

NOT E: Unli ke other metal dete cto rs, the discri min atio n level has little if any effect on the depth capability of the CZ-3D. Note however, that the all-metal, Autotune mode has a wider search pattern and may detect a little deeper. Depth is also determined by the size, shape and conductivity of the target as well as the sensitivity setting of ...

Once you have ident ified and pinp ointed a target, your objective is to recover it quickly and neatly, leaving virtually no trace of your excavation. There are almost as many ways to do this, as there are treasure hunters. Whatever works for you is good enough as long as you don’t break any laws, damage vegetation, or leave uncovered holes.
