TARGET PINPOINTING
After you have identified a target using Discrimination Mode,
press-and-hold the PINPOINT button 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.
Pinpoint as follows:
1. Position the searchcoil just barely off the ground, and to the side of
the target.
2. Now move the searchcoil slowly across the target; you can locate
it by the sound. The target is located directly under where the
sound is loudest.
Narrow It Down:
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 the PINPOINT button.
3. Press-and-hold PINPOINT button again.
4. repeat this narrowing procedure to narrow the field of detection
further.
Note: Depth indication is less accurate
after narrowing.
SeArCHCOIL DrIFT
If you plan to use the
PINPOINT Mode 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 PINPOINT again to
retune.
A 3-segment battery indicator at the bottom of the display indicates the
battery condition.
The detector requires a single 9-volt ALKALINE battery.
Do not use ordinary zinc carbon batteries.
Do not use “Heavy Duty” batteries.
rechargeable batteries can also be used.
If you wish to use rechargeable batteries, we recommend using a
Nickel Metal Hydride rechargeable battery.
The battery compartment is located on the back side of the housing.
Slide the battery door to the side and remove it to expose the battery
compartment.
BATTERY LIFE
expect about 15 to 20 hours of life from a 9-volt alkaline battery.
rechargeable batteries can provide up to 8 hours of usage per charge.
SPEAKER VOLUME AND BATTERY CHARGE
You may notice the speaker volume drop when only one battery segment is
illuminated.
With one segment flashing, low speaker volume will be very apparent.
BATTERY INDICATOR
The 3-segment battery indicator has 4 stages of indication.
These indications are accurate for a 9-volt alkaline battery.
Segments Illuminated Battery Voltage
3 -segments more than 8.4 volts
2 -segments more than 7.5 volts
1 -segment more than 6.8 volts
1 -segment flashing less than 6.8 volts
After the 1st segment begins flashing, expect the detector to shut off within 10
minutes.
A rechargeable battery will usually illuminate two to three segments
throughout most of its useful charge. But as soon as it drains to the 1-segment
level, it will then lose its charge very rapidly.
BATTERY DISPOSAL & RECYCLING
Alkaline batteries may be disposed of in a normal waste receptacle or
recycled. Non-Alkaline batteries should be recycled. In the state of California
all battery types must be recycled. Please refer to local municipalities for
detailed disposal and recycling requirements.
