Overlap Swing
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.
