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 Coin Strike. Depth is also determined by the size,
shape and conductivity of the target as well as the sensitivity setting of the
Coin Strike.
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 Coin Strike search
coil pattern and how it is effected by s weep 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 you Coin Strike will not be
detected unless you overlap your
sweeps.
The conical search
pattern of the Coin Strike
search coil means you'll
get better ground
penetration and
coverage by overlapping
your sweeps.
