Safety Warnings and Precautions

WARNING: When using tool, basic safety precautions should always be followed to reduce

the risk of personal injury and damage to equipment.

Read all instructions before using this product!

1. Handle the Metal Detector carefully at all times. Dropping the Metal Detector can cause

damage to circuit boards and the case, which can cause the product to work improperly.

2. Only use and store the Metal Detector in normal temperature environments. Extremes

in temperature can shorten the effectiveness of electronic devices and melt or damage
plastic parts.

3. Avoid electrical shock. Any metal detector may discover underground power lines,

explosives or other items which when struck could cause personal injury. Do not use this
product in areas where there might be underground electric lines or pipes buried at shallow
depths. Never search in military zones where bombs or other explosives may be buried.
Avoid striking any line known or suspected to be carrying electric power. Do not search
any pipeline, particularly if it could contain a flammable gas or liquid. In areas of uncertain
conditions, use reasonable caution before using the Metal Detector. If there is any question
about a condition being safe of unsafe, do not operate the Metal Detector.

4. Keep the Metal Detector clean. Wipe the housing after each use. The search coil is

washable and can be fully submerged. Never submerge the control housing. Protect the
control housing from rain, blowing surf and heavy mist. Disassemble the stem and wipe it
clean after use in sandy areas.

5. Dress properly. Do not wear loose clothing or jewelry as they can be caught in moving

parts. Protective, electrically nonconductive clothes and nonskid footwear are
recommended when working. Wear restrictive hair covering to contain long hair.

6. Use the right tool for the job. Do not attempt to force a small tool or attachment to do the

work of a larger industrial tool. There are certain applications for which this tool was
designed. Do not modify this tool and do not use this tool for a purpose for which it was not
intended.

7. Stay alert. Watch what you are doing, use common sense. Do not operate any tool when

you are tired.

Safety Warnings and Precautions (continued)

8. Check for damaged parts. Before using any tool, any part that appears damaged should be carefully

checked to determine that it will operate properly and perform its intended function. Check for alignment and
binding of moving parts; any broken parts or mounting fixtures; and any other condition that may affect proper
operation. Any part that is damaged should be properly repaired or replaced by a qualified technician. Do not
use the tool if any switch does not turn On and Off properly.

9. Replacement parts and accessories. When servicing, use only identical replacement parts. Use of any

other parts will void the warranty. Only use accessories intended for use with this tool. Approved accessories
are available from Harbor Freight Tools.

10. Do not operate tool if under the influence of alcohol or drugs. Read warning labels on prescriptions to

determine if your judgment or reflexes are impaired while taking drugs. If there is any doubt, do not operate the
tool.

11. Maintenance. For your safety, maintenance should be performed regularly by a qualified technician.

12. People with pacemakers should consult their physician(s) before using this product. Electromagnetic

fields in close proximity to a heart pacemaker could cause interference to or failure of the pacemaker.

Warning: The warnings, cautions, and instructions discussed in this instruction manual cannot cover all
possible conditions and situations that may occur. It must be understood by the operator that common
sense and caution are factors which cannot be built into this product, but must be supplied by the operator.

Unpacking

When unpacking, check to make sure all parts shown on the Parts Diagram and Parts
List are present. If any parts are missing or broken, please call Harbor Freight Tools at the
number on the cover of this manual.

Preparing to Operate

Adjusting the Stem

1. Turn locknut clockwise until it becomes loose (see Figure 1). Adjust the stem so when
you are standing upright with the detector in your hand, the search coil is level with and about
1/2 to 2 inches above the ground when your arm is relaxed at your side (see Figure 2).

Figure 1

Figure 2

Turn the stem’s lock nut counterclockwise to lock it in place.

Adjusting the Search Coil

Loosen the Knobs at the end of the Search Coil (the Search Coil
should be parallel with the ground). Tighten the Knobs enough
to keep the Search Coil from wobbling or rotating (see Figure 3).

Battery Installation

The Metal Detector requires the use of six AA bateries. Do not
mix old and new batteries and do not mix different types of
batteries.

1. If the Metal Detector is on, turn the volume on the control
housing to OFF (see Figure 4).

Figure 4

3. Insert the batteries into the compartment as

indicated by the polarity symbols (+ and -) which
are marked inside the compartment (see Figure 6)
Replace the cover.
Remember to remove batteries if you do not plan on
using the Metal Detector for a week or more.

2. Press on the battery compartment cover and slide the cover
off in the direction of the arrow (see Figure 5).

Figure 5

Testing Batteries:

Always test the battery power when the Metal Detector does not turn on, has weak

volume, will not tune properly, or has erratic operation.

Rotate VOLUME away from OFF and set OPERATE / BATT to BATT TEST
(see Figure 7).

If the pointer on the viewmeter is between 3 and 6 (green area),
the batteries have enough power to operate the detector. If the
pointer is not in the green area, replace the batteries.

Figure 7

Using Earphones:

Stereo earphones (not included) can be connected to the Metal
Detector. Using earphones saves battery power and makes it
easier to identify changes in the sound patterns. Earphones are
connected to the ear jack on the side of the Control Housing
(see Figure 8). When using earphones, protect your hearing by:

a. Set the volume to the lowest setting before you begin listening. Adjust the volume
to a comfortable level.
b. Never listen at extremely high volume levels; permanent hearing loss can result.
c. Once the volume is set, do not increase it. Over time, your ears adapt to the
volume level, so a volume level that does not cause discomfort might still damage
your hearing.
