coil parallel to the ground
Once outside, practice s weeping the coil
over the ground in a side- to-side motion,
while walking forwar d slowly. Slightly overlap
the previous sweep to ensure a full ground
coverage. An approximate swee p speed is 3
seconds from left to ri ght to left.
It is important to keep t he coil close and
parallel to the ground at al l times. This will
increase detection dept h and response to
small objects. Avoid exces sive brushing
of the coil on the ground, as t his may result
in false signals and inaccur ate target ID’s.
A variation in coil height at t he end of each
swing may also cause confusi ng sounds and
reduce detection depth . 1” (2.5cm)
