Pinpointing the Target
Once the decision has been made to dig, move the
loop off to one side of the target area, squeeze and
hold the TRIGGER on the handle, and "X" the loop
over the spot where you believe the target to be.
Note that the TRIGGER also has a locked forward
position that accomplishes the same thing as
squeezing and holding it.
While the TRIGGER is being held, the loop doesn't
need to be moving to detect the target. The loop
may be moved slowly over the area. The display
will indicate depth in inches and will also show the
strongest reading to aid in pinpointing exactly
where to dig. The shallowest reading on the depth
display, the loudest sound coming from the speaker,
and the two bars lining up with each other, indicate
the center of the target. Don't forget to "X" the
target as pinpointing cannot be accurate unless the
target is swept from at least two different directions.
Once pinpointing is complete, release the TRIG-
GER, or return it to the center position.
Pinpointing takes practice. The standard loop
provided with the DFX™ is a high-powered, 9.5
inch design. This harmonically tuned loop's stron-
gest traits are in the detection depth and ground
coverage areas. If pinpointing becomes difficult or
critical refer to the Advanced Pinpointing Tech-
niques on this page.

Advanced Pinpointing Techniques
1. Targets that are near the surface, because
they give a wider response, are harder to
pinpoint than deep targets. If the trigger is held
and the loop swept over the area, you may note
a shallow depth indication. Lifting the loop
slightly above the ground, releasing and re-
squeezing the TRIGGER and again "X" ing the
target will aid pinpointing.
2. In the Basic Adjustments, DC Sensitivity
(non-motion) directly controls the pinpointing
mode. Lower DC Sensitivity settings pinpoint
shallow targets better.
3. In the PRO OPTIONS under AUDIO, V.C.O.
(Voltage Controlled Oscillator) significantly aids
pinpointing.
4. The depth reading has two indication bars.
The top bar shows the current distance from
the target, and the bottom bar shows a memory
of the strongest reading. These two bars will be
even with each other when the loop is directly
over the center of the target.
