Effects of sweep speed,
ground mineralization
and search mode
Unlike other metal detectors, the discrimination settings have little if any effect on
the depth capability of the ID EDgE Depth is also determined by the size, shape
and conductivity of the target as well as the sensitivity setting of the ID EDgE.
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 EDgE search
coil pattern and how it is effected by sweep speed,
ground mineralization and search mode.
4
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 EDgE will not be detected
unless you overlap your sweeps.
The conical search
pattern of the ID EDgE
search coil means
you'll get better ground
penetration and
coverage by overlapping
your sweeps.
