The conical search
pattern of the ID Excel
search coil means
you’ll get better ground
penetration and
coverage by overlapping
your sweeps.
5.
Keep the search coil moving at a comfortable
rate.
6.
Take your time. If you walk too fast you can
overlap your sweeps and you’ll miss a lot of ground.
If you swing your coil too fast, you could lose some
sensitivity to deep and/or small targets.
7.
The illustration below shows the ID Excel search
coil pattern and how it is effected by sweep speed,
ground mineralization and search mode.
1. Minimum depth
a.
Very slow or very fast sweep speed
b.
Highly mineralized soil.
2. Good depth
a.
Moderate sweep speed
b.
Moderately mineralized soil
3. Maximum depth
a.
Moderate sweep speed
b.
Non-mineralized soil
4. Missed target
Many targets well within the range
of your ID Excel will not be detected
unless you overlap your sweeps.

Unlike other metal detectors, the discrimination settings have little if any effect on
the depth capability of the ID Excel. Depth is also determined by the size, shape
and conductivity of the target as well as the sensitivity setting of the ID Excel.
