AN IMPORTANT MESSAGE FROM MINELAB

We ask YOU, as a responsible detector operator, to take all due

care regarding the environment.

Minelab cannot stress enough the importance of being responsible

when recovering targets.

BACKFILL EVERY HOLE YOU DIG.

If care and consideration is taken, during and after the removal of

targets, especially with respect to the back filling of holes, this

should ensure the continued access to areas for prospecting and

treasure hunting. This will also ensure that the pristine condition of our

beautiful bushland, forests and dry land areas is maintained with a

minimum of damage.

Minelab is working with you towards preserving our natural

environment so that the benefits of gold prospecting and treasure

hunting can continue to be enjoyed in the years to come.

Every prospector and treasure hunter around the world and the

staff of Minelab thank you for your continued efforts towards

protecting the environment.

take care

The ‘GP 3000’ is a high quality electronic instrument. It has been designed for

professional gold prospecting use and the electronics circuitry is encased in a

rugged housing. Take care of your detector in the following way:

Keepthe detector cleanand dry.Itisvery importanttokeepallelectricalconnectorsclean anddry.

The control box is not waterproof,eventhough it has been designed to be water-resistant.Take

care to avoid it becoming wet.

The coil is water resistant and may be used in rain or wet conditions. The coil is not waterproof. Do not

immerse the coil in water.

Regularly replace such items as teardrop washers and skidplates to give long life to your detector.

Do not expose the detector to high temperatures or leave it in the sun for longer than is necessary.

Shading will help protect it. Do not leave the detector in a closed vehicle, especially in the sun.

The coil housing will eventually wear through if you scrub the ground with it while searching. Use of a

Introduction

The‘GP 3000’incorporates new

technological advances and control

functions which have resulted in a

detector that combines stable and

effective ground balancing with

depth and sensitivity.

INTRODUCTION

GLOSSARY OF COMMON TERMS

USER INFO

Halo Effect After a metal object has remained undisturbed in the soil for a

considerable amount of time, a diffusion occurs around the object.

This has the effect of the object appearing to the detector to be a

larger size.

Hot Rocks A hot rock is an individual rock which has a particularly high degree

of mineralisation as compared to the average ground around it. Due

to this high difference, the detector does not have the opportunity to

ground balance on the individual rock so therefore gives a false signal.

Interference Electricity or radio waves in the area being detected can cause

instability or chattering of the detectors threshold.

The types of interference commonly occur due to power lines,

underground cables, radar, other detectors or climatic conditions like

thunderstorms.

Mineralised Ground Most ground contains certain minerals which can cause false signals

to be given by a detector. Heavily mineralised ground requires

different ground processing than does neutral or lightly mineralised

ground (see Ground Balance).

Ground containing heavy salt concentrations require entirely

different processing again (see salt).

Monoloop Coils Monoloop coils are the style of coil where the multiple strands of

wire are wound in a single loop around the circumference of the coil.

The field of search of Monoloop coils tend to be cone shaped.

Non - Ferrous Metals Metals not containing significant levels of iron. Non-ferrous metals

are non-magnetic such as Gold, Silver, Copper, Brass, Lead or

Aluminium.

Pinpoint The method of locating the precise location of a target prior to

digging. Pinpointing uses the design of the search coil windings to

determine the exact position of the detected target.

RX RX refers to the response or electromagnetic field which is received

back by the coil and is used by the control box circuitry to detect a

metal item in the ground.

ABOUT THIS MANUAL

INTRODUCTION

GLOSSARY OF COMMON TERMS

Control Box The control box encloses the electronic circuitry of the detector.The

control box originates the TX (transmit) signals sent by the coil and

interprets the RX (receive) signals detected by the coil. All user

selectable functions (knobs & switches) are located on the front and

rear panels of the control box.

Discrimination Theabilityofametaldetectortoestimateifalocatedtargetismade

fromferrousmetal (iron or steel) or non-ferrous metal (non-magnetic).

Double D Coils Double D coils are coils that have two windings of wire that overlap

in the shape of two D's (one reversed). The characteristics of a

Double D coil are stability, especially in heavily mineralised ground,

good depth and sensitivity and a very thorough search pattern.

Electromagnetic Field Commonly called the 'signal from the coil'. An electromagnetic field is

generated within the wire windings of the search coil and this field is

pulsed or sent into the ground. The presence of a metal target in the

ground will disturb the pattern of this field and this disturbance is

registered by the receive system of the detector and indicated to the

operator by an audible target signal "beep".

False Signal False signals are signals, which sound similar to target signals but

are caused by other factors. Common causes for false signals are

incorrect ground balance, hot rocks, signals caused by knocking the

coil on obstacles, etc. With experience, the operator will learn

methods to minimise false signals and to hear subtle differences

between target signals and false signals.

Ferrous Metals Metals composed of or containing iron.A ferrous item is one which is

Batteries

Spare12A/hrbatteries can be an advantage, especially if travelling

into the outback.

Asmaller light-weight battery is also available from Minelab. This is

rated at 4.5A/hr and gives approx. 3 - 4 hours running time per charge.

The weight of this battery is 968g.
