METAL DETECTOR

MODEL NO.: GC1035

2

This metal detector is a professional metal detector. As a sophisticated electronic device,
the most difficult aspects in metal detecting have been automated.

If you are fresh in using metal detector, we highly recommended you:

1. Set the sensitivity to a low level in the event of false signals. Always begin at a
reduced sensitivity level when using. After you have become familiar with the
detector, you may try it at full sensitivity.

2. This detector is for outdoor use only. Do not use indoors. Many home appliances
can emit electromagnetic wave, and will interfere with the detector. For indoor
testing, turn the sensitivity down and keep the search coil away from facilities such
as microwave ovens, computers and TVs. If your detector beeps erratically, turn off
the electronic appliances and lights, especially those with dimmer switches.

3. Read this manual. Most importantly, review the BASIC OPERATION.

1．TERMINOLOGY

The following terms are used throughout the manual, and are standard terminology
among detectorists.

 ELIMINATION - Reference to a metal being "eliminated" means that the detector

will not emit a tone, nor light up an indicator, when a specified object passes through the
coil’s detection field.

 DISCRIMINATION - When the detector emits different tones for different types of

metals, and when the detector "eliminates" certain metals, we refer to this as the
detector "discriminating" among different types of metals. Discrimination is an important
feature of professional metal detectors. Discrimination allows the user to ignore trash
and otherwise undesirable objects.

 NOTCH - Notching is the elimination of an item, or range of items, within the

metallic spectrum. We “notch-out” an object, or objects, selectively.

 AUTO NOTCH - It eliminates trash metals automatically and keep the detection for

most coins. AUTO NOTCH range is preset in the factory and not adjustable..

 RELIC - A relic is an object of interest by reason of its age or its association with

the past. Many relics are made of iron, but can also be made of bronze or precious
metals.

 IRON - Iron is a common, low-grade metal that is an undesirable target in certain

metal detecting applications. Examples of undesirable iron objects are old cans, pipes,
bolts, and nails. Sometimes, the desired target is made of iron. Property markers, for
instance, contain iron. Valuable relics can also be composed of iron; cannon balls, old
armaments, and parts of old structures and vehicles can also be composed of iron.

 FERROUS - Metals which are made of, or contain, iron.
 GND TRAC - Ground Track is the process of finding the exact location of a buried

object. Long-buried metals can appear exactly like the surrounding soil, and can
therefore be very hard to isolate from the soil

 PULL-TABS - Discarded pull-tabs from beverage containers are the most

bothersome trash items for treasure hunters. They come in many different shapes and
sizes. Pull-tabs can be eliminated from detection, but some other valuable objects can
have a magnetic signature similar to pull-tabs, and will also be eliminated when
discriminating out pull-tabs.

 GND BAL - Ground Balancing is the ability of the detector to ignore, or "see

through," the earth’s naturally occurring minerals, eliminates false signals from severe
ground conditions, and only sound a tone when a metal object is detected.

 SURF ELIM - Surface Elimination can improve the accuracy of detection result in

soil with mass trash metal. It restrains the signal from trash metal in soil surface layer,
and balance the signal from large target.

2．ASSEMBLY

2．1 ASSSEMBLY

Assembly is easy and requires no tools：

1． Open the packing, and take out all parts.
2． Join the search coil and the lower

stem (fiberglass-made, in black
color)，then tighten the bolt.

3． Press the silver button on the upper

end of the lower stem, and slide the
lower stem into the upper stem.
Adjust the stem to a length that you
feel comfortable when you stand upright with the detector in your hand, and the
search coil is level with the ground with your arm relaxed at your side. Then
counter-clockwise rotate to tighten the
lock cam.

4． Wind the search coil cable around the

stem. Insert the search coil’s plug into

the search coil jack on the detector’s control housing.

Caution:

 Do not over-tighten the search coil or use tools such as pliers to tighten it.

 The search coil’s plug fits into the connector only in one way. Do not force the plug

and also do not pull on the cable or you could damage it.

5． Assembly of the arm support: Insert the aluminum stem on the arm support into the

stem at the end of the main box and tighten the fixing screw properly.

2．2 BATTERIES

Caution：

· This metal detector is powered by two 9-Volt alkaline batteries (not supplied).

· Only fresh and proper type of alkaline batteries is recommended

· Do not mix the old and new batteries or different types of batteries.

Installation

1. Be sure the power switch is at off-position.

2. Slide the battery cover off in the direction of the arrow.

3. Take out two battery connectors from the compartment。

4. Join the battery polarities with the connectors.

5. Re-install the battery cover.

Warning：

Dispose of old batteries promptly and properly, do not bury or burn the batteries.

Note：

· If you don’t plan to use the unit for a week or more time, remove the batteries. Batteries

can leak chemicals that can destroy electronic parts.

·To extend the battery lift, exchange the left and right battery after 3-4hours of operation.

· “LOW BATT” icon will display on bottom right corner of the LCD when the batteries are

needed to be changed.
