After you have identified a target using a motion mode of detection, press and hold
the to identify the target's exact location. This technique can yield more
information about the target's shape and size and also find its exact location to
facilitate extraction.
1. Press and hold
Pinpoint as follows:
2. Position the searchcoil just barely off the ground and to the side of the
target.
3. Move the searchcoil slowly across the target.
The target is located directly under where the sound is loudest.
Retuning in the Pinpoint Mode is useful in narrowing down the location of a

again. When the user releases the

1. To narrow the response further, position the center of the searchcoil near
the center of the response pattern, but not directly over the center.
2. Release .
3. Immediately press-and-hold again.
4. Repeat this narrowing procedure to narrow the field of detection further.
Note: Depth indication is less accurate after narrowing.
COIL DRIFT
If you plan to use PINPOINT for continuous searching, realize that drift will
occur over time, causing the detector to gain or lose sensitivity. Periodic
retuning of the detector is required to minimize drift; release and press
periodically to retune.
1. Sweep over target in narrowing side-to-side patterns.

2. Visualize a "center line" on the ground where "beep" occurs.
3. Rotate 90° and now sweep along this imaginary line.
4. Visualize a second "center line" on the ground where "beep" occurs.
5. The "X" center pinpoints the target location.

The Menu is located on the left side of the screen. During normal operation the
Menu is inactive and the text icons are faded. Press the
through the menu options. When active, the icon will be bold. Each press of
the moves to the next Menu item. Use
adjustments up or down. Here is a description of the Menu options:
Adjust speaker volume from 0 to 20. The default setting is 7. With a setting of

VOLUME

"0", the detector will function as normal but it will not emit any sound when
targets are detected.
The F44 has FeTone™, adjustable Iron audio, a feature to reduce the volume
of iron targets to minimize user fatigue.
Volume settings of 10 – 20 are available to control the volume level of the iron
targets. As you increase volume from 10 to 20, iron-volume changes from
silent to maximum. At each of the 10 – 20 volume settings, nonferrous target
response remains at maximum volume. At volume settings 0 – 9 both ferrous
and nonferrous targets have equal volume.
Example: at volume setting 15, nonferrous target volume is maximum, ferrous
target volume is at "5", or half volume.

Volume settings will be saved when the detector is turned off.
Adjust the sensitivity from 1 to 20. The default setting is 12. The higher the
SENS
number, the more sensitive the detector.
If the detector beeps erratically or beeps when there are no metal objects
being detected, reduce the sensitivity.
The searchcoil produces a magnetic field and then detects changes in that
magnetic field caused by the presence of metal objects. This magnetic field
the detector creates is also susceptible to electromagnetic energy (EMI)
produced by other electronic devices. Electric fences, cell phones, cell phone
towers, etc., all produce EMI which can interfere with the detector and cause
it to beep when no metal is present and sometimes to beep erratically.
Sensitivity settings will be saved when the detector is turned off.
