Detecting Techniques
7.1 Searching
The SD2200v2 is a 'motion' detector, which means that it must be moving
in relation to a target in order to detect it. DO NOT set your shaft length too
short. If the coil is too close to your body it may detect your pick, the battery,
or any other metal that you may be carrying.
Note: DO NOT wear steel cap boots or shoes with metal eyelets when
detecting.
If you find that you are getting false signals as you sweep the coil, check
that they are not produced by any metal that you are carrying. Move the
coil closer and further away from your body to determine if the signals are
coming from items such as your pick or the battery. If the signals are from
these items you must increase the distance between them and the coil.
The coil should be swept over the
ground in a side-to-side motion.
As the operator moves slowly
forward, the search pattern
resembles a snaking path. To
ensure that the ground is
thoroughly searched, it is
advisable to approach the area
from three directions as shown
in figure 8.
While sweeping the coil it is
important to keep it parallel to
and at a constant height from the
ground at all times. The easiest
way to achieve this is to have the
coil lightly brushing the ground.
Be aware of any tendency to
raise the coil at the ends of each
sweep as this will reduce the
detection depth (see figure 8).
