with less waste metal, a PASTURE can be chosen.In places with more
waste metals, you can choose PARK to judge the metal category with
the help of its three-audio function.On wet sandy beaches, especially
beaches, SAND is available.To exclude metals with low conductivity,
select the DISC.
3. Select sensitivity
The detector always hopes that the sensitivity of the detector is very
high. However, in the higher sensitivity range, the detector is very
sensitive to electromagnetic interference from nearby power lines or
cables, and it also reacts abnormally to mineralization or conductivity in
the soil. If you move the probe in a place where there is no metal in the
detection area, the detector often sends out unstable false signals,
please reduce the sensitivity.
If you and your partner turn on the detector at the same time, please
keep a distance of more than 10 meters and reduce the sensitivity
appropriately.
4.
Move the search coil
During the detection, the search coil should be moved at a uniform
speed, do not go fast and slow. The search coil is parallel to the ground
and remains about an inch, not swinging high and low above the ground
like a pendulum. (see graph 18)

Scan the coil from one side to another at about 3 feet (1 m) per second.
