This metal detector is intended for locating buried metal objects. When
searching for metals, underground or on the surface, you have the following
challenges and objectives:
1. Ignoring signals caused by ground minerals.
2. Ignoring signals caused by metal objects that you do not want
to find, like nails.
3. Identifying a buried metal object before you dig it up.
4. Estimating the size and depth of objects, to facilitate digging them up.
5. Eliminating the effects of electromagnetic interference from other
electronic devices.
Your metal detector is designed with these things in mind.
1. Ground Minerals
All soils contain minerals. Signals from ground minerals can interfere with
the signals from metal objects you want to find. All soils differ, and can differ
greatly, in the type and amount of ground minerals present. This detector
has proprietary circuitry to automatically eliminate interfering signals from
minerals that occur naturally in the ground.
NOTE: This detector will not completely eliminate interference from all types
of minerals. For example, the detector IS NOT designed for use on wet
sand saltwater beaches. Another example of soil this detector will not
eliminate is any soil containing large concentrations of iron oxides, which are
usually red in color.
2. Trash
If searching for coins, you want to ignore items like aluminum foil and nails.
You can see the Target-ID value of the buried objects, listen to the sounds
and then decide what you want to dig up. Or you can eliminate unwanted
metals from detection by using the DISCRIMINATION feature.
3. Identifying Buried Objects
Metal objects are identified along the 9-segment Conductivity Arc. This scale is an
indicator of the relative electrical conductivity of different objects. Segments to the
right indicate more conductive targets. Iron objects, which are usually of lesser
value, illuminate on the left-most segments. Silver objects illuminate on the right-
most segments.
4. Size and Depth of Buried Objects
The 3-segment graphic indicates the relative depth of a buried metal object.
This graphic can indicate the relative size of different objects or their distance from
the searchcoil. For a given object, the more distance between it and the searchcoil,
the more arrows illuminated.

THE BASICS OF METAL DETECTING

Press-and-hold
to activate the Pinpoint feature.
Searchcoil motion is not required; a motionless searchcoil over a metal target
will induce sound.
Audio is V.C.O. The 2-digit number displayed indicates target depth, in inches.
The scale in calibrated to coin-sized objects.
How to Pinpoint
After you have identified a target, press-and-hold
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. Press and hold
.
2. Position the searchcoil just barely off the ground, and to the side of the
target.
3. Now move the searchcoil slowly across the target, and 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 .
PINPOINT
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.
Pinpointing using motion modes (without
):
1. Sweep over target in narrowing side-to-side patterns.
2. Take note of the spot on the ground where “beep” occurs.
3. Step 90° to the side of the target.
4. Sweep searchcoil over.
5. This pinpoints the target location with an “X”.
