IN THE FIELD TECHNIQUES
- Motion modes
When pinpointing a target, try drawing an “X”,
as illustrated, over where the tone is induced.
PINPOINTING
Accurate pinpointing takes practice
and is best accomplished by
“X-ing” the target area.
1.
Once a buried target is indicated
by a good tone response,
continue sweeping the coil over
the target in a narrowing
side-to-side pattern.
2.
Take visual note of the place on
the ground where the “beep”
sounds.
3.
Stop the coil directly over this
spot on the ground.
4.
Now move the coil straight
forward and straight back
towards you a couple of times.
5.
Again make visual note of the
spot on the ground at which
the “beep” sounds.
6.
If needed, “X” the target at
different angles to “zero in” on
the exact spot on the ground at
which the “beep” sounds.
COIL MOVEMENT
When swinging the coil, be
careful to keep it level with the
ground about one inch from the
surface. Never swing the coil like
a pendulum.
CORRECT
WRONG
The
coil
should
be swung
in a
half-
circle
movement
as
illustrated
here.
Repeat this
motion
every step
you take to
guarantee that
the area is
covered thoroughly.
