AT Pro International™  41

In order to fully search an area, overlap the swings of your searchcoil by half 

the length of the coil (about 14 cm). Sweep the searchcoil in a straight line 

or with a slight arc at a sweep speed of about 1m/sec.

•  Walk slowly as you scan your searchcoil in a straight line  
  from side to side at a speed of about 1 meter per second.  
  Advance the searchcoil about half the length of the  
  searchcoil at the end of each sweep.

Tips for saltwater use:

 Hunting in a saltwater environment 

is challenging for any Continous Wave (VLF) metal detector.
Saltwater is conductive and produces signals similar to foil. 
Although the AT Pro is not specifically designed for saltwater 
use, it can be used in this environment. The operator can 
expect stable operation in dry or moist sand and when the 
searchcoil is completely submerged. 
  Saltwater-saturated sand, surf and black sand may require 
special techniques. To achieve stable operation:
  •  First, Ground Balance the detector to the area that will  
    be hunted (see pages 31–32). Saltwater beaches  
    typically Ground Balance between 0 and 20.
  •  If  necessary,  reduce  the  Sensitivity  until  the  signals  
    become stable.
