For best results, the battery pack must be

recharged whenever the detector has been

unused for a long period of time.

A battery icon displayed on the Control Panel Status

Bar (page 10) indicates the present charge level, and

provides advanced warning of the need to recharge or

replace the battery. The battery charge level is displayed

in ﬁve segments, which will gradually decrease during

operation relative to the voltage left in the battery. When

the last segment disappears, the ‘empty battery’ icon

will begin to ﬂash and the battery low sound will emit

every 20 seconds. If the detector is still operating at this

time the voltage will drop to a point when a ‘low battery’

message will appear and the detector will turn itself oﬀ.

NOTE

The detector regulates the output voltage

so that its performance remains constant

regardless of the charge remaining in the

batteries.

Charging Batteries

Recharge the Lithium-Ion Battery Pack

1. Remove the battery pack from the detector and

place it into the charger unit, ensuring that the

connector pins line up.

2. Insert the plug pack, cigarette lighter or direct

connection battery cable connector into the socket

on the right hand side of the charger unit.

For further information on the Map, see page 13.

GPS

The Global Positioning System (GPS) is a space-based

satellite navigation system that provides location and

time information from any location where there is an

unobstructed line of sight to four or more GPS satellites.

The location and navigational elements of the Map work

in conjunction with the Global Positioning System (GPS).

By default the GPS receiver is turned oﬀ and must be

turned on through the Setting page (page 21). Once

GPS is turned on a ﬂashing GPS icon will appear on

the Status Bar. When an absolute position ﬁx has been

established (which may take several minutes), the GPS

icon on the Status Bar will stop ﬂashing and remain static.

On entering the Map a marker will be displayed at the

centre of the screen to represent your initial start location.

If there is a valid GPS position ﬁx, movement will be

displayed on the Map as a series of dots that form a

GeoTrail.

On the GPZ 7000, GPS provides the capability to store

location data relating to FindPoints and WayPoints, and to

record GeoHunts. By default GPS is turned oﬀ and must

be turned on through via Settings page (page 21).

NOTE

If there is no WayPoint, FindPoint or GeoHunt

near the current location, the Map may be

blank.

indicate ﬁnd locations and points of interest. They will

be displayed at a consistent size regardless of the zoom

level, but those in close proximity will be overlapped. By

default FindPoints and WayPoints are displayed with their

names, but if space is limited the names can be hidden

(page 28).

FindPoint

A FindPoint stores the location and details of a

target. When you choose to store a FindPoint

(page 29), the GPZ 7000 stores the following

information:

Your FindPoint information can be used for future

reference within the detector and with the XChange 2 PC

application (page 31).

Map

WayPoint

A WayPoint is similar to a FindPoint with the

exception that no detector related information

is stored. The WayPoint is used to record a point

of interest or location to which you may choose

to return in the future. When you choose to store a

WayPoint the GPZ 7000 stores the following information:

•Location

•Time and date

You can also create a WayPoint as a navigation point

on Google Maps using the XChange 2 PC application

(page 31).

GeoTrail

GeoTrail position information is recorded every second

and can be represented on the screen by a series of dots

that form a trail. If a GeoTrail is being recorded as part of

a GeoHunt, the trail will be maroon, otherwise it will be

blue.

GeoHunts

When the GeoHunt function is active, the GPZ 7000

stores your position information while you are detecting.

It allows you to see a map view of the ground you have

covered, and records the location, time and detector

settings used. FindPoints and WayPoints stored while

a GeoHunt is active are displayed and stored with the

GeoHunt.

When you activate the GeoHunt function, the GPZ 7000

stores the following information:

•Periodic location (GeoTrail)

•Time

•Detector settings and coil information

•FindPoints and WayPoints

You can upload your GeoHunts to your PC and view

them on Google maps using the XChange 2 application

(page 31).

North Marker

The North Marker is displayed at the top right of

the screen. It indicates a northerly direction in

relation to the detecting trail.

Coordinates

Lat: __.__ deg.

Version Information

Detect

The Detect page contains all of the primary detecting

functions:

•Quick Start

•Target Type

•Ground Type

•Noise Cancel

•Sensitivity

•Volume

Quick Start

Quick Start oﬀers minimal setting adjustment, ideal for

beginner users. When Quick Start is selected, the Quick

Start wizard is launched. This will guide you through the

Quick Start process to get you detecting quickly and

easily.

Target Type

The Target Type function allows you to optimise your

detector to search for speciﬁc target types.

The available options are:

•Small Nuggets (Default)

•General

•Deep Only

Small Nuggets

This setting is ideal for searching for nuggets between

0.1 and 10 grams and also has good performance for

detecting larger nuggets in shallow ground. This setting

utilises new technology in the GPZ 7000 which provides

a substantial performance increase over existing metal

detectors in detecting smaller nuggets that others have

missed.

General

This setting provides good all round performance in

detecting nuggets of all sizes and at all depths.

Deep Only

This setting is speciﬁcally designed for searching for

deeply buried targets. Deep targets produce complex and

subtle audio responses, and as such this setting should

only be used by highly skilled operators. Shallow targets

will not present well on this setting when compared to

the ‘Small Nuggets’ or ‘General’ settings. This setting is not

recommended for general use.

When changing the Target Type setting, the threshold

tone will become silent for approximately one second

once a new setting is selected.

Ground Type

When detecting in ground with high levels of iron

mineralisation, movement of the detector over the

ground can produce false target signals. These unwanted

target signals are known as ground noise. The GPZ 7000

detector has been designed to remove unwanted ground

noise. The Ground Type setting controls the amount of

unwanted ground noise that the detector will remove

from the audio.

The available options are:

•Diﬃcult (Default)

•Normal

Dicult

This setting is recommended as gold is usually found in

areas with high levels of iron mineralisation.

Normal

This setting should only be used in areas where the

ground is known to be ‘quiet’ ground. If unwanted ground

noise is heard while operating in the ‘Normal’ setting, the

operator should change to the ‘Diﬃcult’ setting.

When changing the Ground Type setting, the threshold

tone will become silent for approximately one second

once a new setting is selected.

Detect

Noise Cancel

The Noise Cancel function allows you to eliminate

electromagnetic interference (EMI) or ‘noise’ from the

detector.

The GPZ 7000 may become noisy due to electrical

interference from power lines, electrical equipment or

other detectors operating close by. The detector interprets

this interference as inconsistent, erratic detections.

The available options are:

•Auto (Default)

•Manual

Auto Noise Cancel

Auto Noise Cancel automatically scans and listens to every

channel, and selects the one with least interference. Auto

is the recommended setting.

1. Make sure there are no large targets or obvious

sources of EMI close by, then raise the detector coil

until the detector shafts are horizontal to the ground.

2. Select the Noise Cancel icon then Auto to initiate

Auto Noise Cancel.

3. Automatic channel selection will commence. Keep

the detector still during the selection process, which

may take up to 55 seconds. Press the back button to

terminate Noise Cancel at any time.

The screen will indicate when the Noise Cancel is

complete.

Manual Noise Cancel

The Manual setting allows you to manually select and

listen to each channel for the least interference.

To manually adjust Noise Cancel:

1. Make sure there are no large targets or obvious

sources of EMI close by, then raise the detector coil

until the detector shafts are horizontal to the ground.

2. Select the Noise Cancel icon, then select Manual.

3. Press the left or right arrow buttons to select a

channel. Pause and listen to the interference coming

from the detector. Keep the detector still during this

process.

Once the channel with the least interference has

been found, press the Select button exit the menu.

Sensitivity

Sensitivity controls the detector’s response to received

signals. These signals can include desirable signals

from nearby metal, as well as undesirable signals from

electronic noise, and noise due to ground response.

Increasing the sensitivity level may make targets more

detectable but may also increase detector noise due to

these noise inﬂuences.

You can adjust the sensitivity setting to your desired level.

Adjust Sensitivity Settings

Select Sensitivity on the Detect page. An adjustment

range from 1 to 20 will appear. Use the left and right

arrow buttons to increase or decrease the Sensitivity; the

threshold tone will become silent for approximately one

second with each press. Press Select when done.

Volume

Range: 1–20

Factory Preset: 8

Volume controls the ampliﬁcation of a target’s audio

response, relative to the target signal strength. This audio

setting is most similar to volume adjustments in other

devices (e.g. radio or television volume controls).

With a setting of 1 the target signal will not be ampliﬁed.

Weak target signals will sound quiet, medium target

signals will sound mid-range and strong target signals will

sound loud. There will be greater diﬀerentiation between

target signal strengths; however, weak signals will be

harder to hear.

With a setting of 20, all target signals will be ampliﬁed to

a loud audio response. At this setting there will be less

diﬀerentiation between medium and strong signals, but

weak target signals will be easier to hear.

Detect Plus

The Detect Plus page contains settings for the detector’s

headphones, wireless speaker, wireless headphones, and

Ground Balance functions.

The available Items are:

•Threshold Level

•Volume Limit

•Threshold Pitch

•Ground Balance Mode

Threshold Level

Range: 1–50

Factory Preset: 30

The constant background ‘hum’ produced by the detector

is called the Threshold. Variations in the Threshold help

you to hear very small and deep targets.

The Threshold is controlled by Threshold Level and

Threshold Pitch. The correct adjustment of both Threshold

settings will depend on your hearing and environmental

noise such as wind, waves and machinery.

Adjust the Threshold Level to a faint, audible hum. This

will highlight variations in signal response which may

indicate the presence of a target. If the soil conditions

change the Threshold Level may need adjustment.

If the Threshold Level is too high, faint targets will be

harder to hear above the Threshold ‘hum’.

If the Threshold Level is too low, the slight variation

caused by a small or deep target may not be suﬃcient

to hear. Adjusting the level to below an audible level

will ensure silent operation but could mask the audio

response from small or deep targets.

Volume Limit

Range: 1–20

Factory Preset: 12

The Volume Limit sets the maximum volume for target

signals. When detecting, the sound produced by a target

can be very loud. Adjust the Volume Limit to ensure that

loud targets do not hurt your ears.

NOTE

A high Volume Limit will allow a greater

diﬀerence between a small and large target.

A low Volume Limit will reduce the volume

diﬀerence between small and large targets.

Detect Plus

Threshold Pitch

Range: 1–100

Factory Preset: 50

Threshold Pitch allows you to adjust the pitch of the

Threshold tone. Hearing will vary between individuals, so

adjust the Threshold Pitch to a level that is comfortable

for your hearing.

Ground-Balance Mode

The Ground Balance Mode setting allows you to select the

method for balancing out unwanted ground noise.

The available options are:

•Auto (recommended)

•Manual

Auto

Auto is the recommended setting for Ground Balance

Mode. Auto ground balance automatically measures the

ground mineralisation levels and adjusts the ground

balance as necessary to maintain stability and detection

depth.

In Auto mode the ground balance will automatically

stabilise, after power on or a settings change, within 10 to

15 seconds of normal detecting. Optionally, the Quick-Trak

function can be used to speed up the automatic

balancing process.

Performing a Quick-Trak

1. Find a metal free location, near to the area being

detected, where the detector can be swung back and

forth repeatedly over the same ground.

2. While swinging the detector back and forth over the

same ground, press and hold the trigger button.

3. A wizard animation will appear on the screen to

demonstrate the required action. The wizard can be

turned oﬀ via Wizards on the Preferences Page.

4. Audio will provide feedback during the Quick-Trak

process. The audio response from moving the coil

over the ground should quickly reduce. Once the

audio response has stabilised, release the trigger to

complete the Quick-Trak operation.

The Quick-Trak operation can be repeated as required.

Manual

When set to Manual Ground Balance Mode, the detector

will not automatically maintain ground balance. When

using manual mode you must regularly perform a

Quick-Trak to maintain an accurate ground balance.

NOTE

For best Quick-Trak results, swing at a

steady rate, keeping the coil as close to the

ground as possible without touching the

ground.

should allow you to comfortably

grip the handle. Your elbow should

sit just above the back of the

armrest and the detector should

feel like an extension of your

forearm.

Adjust the Length of the Shafts

The mid shaft can be adjusted to any length between

fully extended and fully retracted. Adjust the mid shaft to

the correct length and secure the cam lock on the upper

shaft to lock the shaft position.

A correct shaft length will allow you to swing the coil over

the ground without uncomfortably stretching or stooping.

If the coil is too far from your body it will be diﬃcult to

balance and manoeuvre while detecting. If the coil is too

close to your body it may detect your digging tools or

any other metal which you are carrying, causing confusing

sounds.

Adjust the Angle of the Coil

Loosen the bolts that connect the lower shaft to the coil.

Note that these bolts are retained and are not designed

to be disassembled by the user. The bolts should be loose

enough to allow the coil to be moved for adjustment, but

tight enough that the coil can hold its position.

While holding the detector as if detecting, lightly press

the coil to the ground until it sits ﬂat/parallel with the

ground. The coil should remain parallel when lifting to the

sweep height, approximately one inch (25 mm) above the

ground.

Tighten the bolts just enough to hold its position.

Sweeping the Coil

CAUTION

Sweeping the coil incorrectly can miss targets

or generate false signals.

You will obtain the best performance when the coil is

swept close and parallel to the ground at all times. This

will increase detection depth and improve the response

to small objects. Avoid excessive brushing of the coil on

the ground.

Though the coil assembly is rigid and durable, sudden

jolts or bangs can cause random signals, as well as

excessive wear and tear. Careful sweeping will ensure the

coil performs to an optimum level at all times.

Practice sweeping the coil over the ground in a side-to-

side motion while slowly walking forward at the end of

each sweep. Slightly overlap the previous sweep to ensure

full ground coverage. An average sweep speed is four

seconds from left to right to left.

If you are getting signals from a visibly clear patch of

ground, there could be buried metal objects. Try ﬁnding

another area to practice.

Types of Targets

Metal objects are referred to as targets. Targets are

comprised of ferrous and nonferrous metals. Ferrous

metals are those containing iron; such as steel, nails and

some types of coins. Nonferrous metals are those which

are not magnetic, such as gold, silver, copper, bronze and

aluminum.

You may wish to ﬁnd a range of both ferrous and

nonferrous targets.

Examples of common targets:

•Desired high ferrous target – war relic

Detecting Basics

•Undesired high ferrous target – iron nail

•Desired nonferrous target – gold coin

•Undesired nonferrous target – pull-tab

•Desired target – gold nugget

Detector Sounds

Turn the detector on. The constant background ‘hum’

produced by the detector is called the Threshold.

Variations in the Threshold allow you to hear very small

and deep targets. It is also used to help distinguish

between desired and undesired targets.

The detector may also produce false signals (Noise) when

not over the ground or with the coil held motionless.

These may not be target signals, but surrounding

electromagnetic interference (EMI). You can minimise

false signals by performing a Noise Cancel (page 17),

performing a Ground Balance (page 20), or by reducing

the Sensitivity of the detector (page 18). It is generally

better to try to reduce false signals by adjusting Noise

Cancel and Ground Balance before resorting to reducing

the Sensitivity.

Sweep the coil across the targets one at a time. Observe

the Detect screen and listen to the sounds of the detector

as it passes over each object. The audio response will give

you detailed information about the Target.

An audio signal is the sound produced by the detector

when a target is detected. Large targets or targets close to

the ground surface emit louder signals.

Very large objects close to the coil may overload the

detector electronics. When this happens, the detector

displays an overload message and emits a fading sound,

which repeats until the coil is moved away from the

source of the overload. Overloading is not harmful to the

electronics of the detector.

It is best to operate the detector only when outdoors and

away from sources of electromagnetic interference (EMI)

such as power lines and phone towers. These sources

may cause the detector to perform erratically, giving

false signals. There are also many metallic objects inside

a house, such as nails in the ﬂoor, reinforcing in the walls,

televisions and other household appliances, that might

interfere with or overload the electronics of the detector.

It is important to understand the sounds produced when

you make a valid or invalid button press. You will usually

encounter these sounds while adjusting settings via the

main menu. A valid button press makes a ‘bip’ sound; an

invalid button press makes a ‘ba-dump’ sound.

Each time you turn the detector on, the last screen used

before shutting down will appear. For example, if the

GPZ 7000 was operating in the Menu screen when turned

oﬀ, this screen will appear when the detector is turned

back on.

Detecting Tips and Techniques

Follow these hints and techniques to help you to utilise

the power of your GPZ 7000 detector, to ensure that every

trip is a success.

•Metallic targets will usually give a ‘solid’ sounding signal

when the coil is swept across the object from any

direction. A metallic target generally produces a short,

sharp and mostly symmetrical signal. Ground noises

usually give a broad uneven signal when the coil is

swept from diﬀerent directions, and often may only give

a signal from one direction and no signal on the return

sweep.

•If you are not sure if the sound is ground noise or a

target signal you should always investigate. Scrape a

shallow hole about 30mm (1”) deep over the suspected

target. Sweep the coil over the hole at the original

ground level. Do not dip the coil into the hole. If the

signal has decreased in volume or is less deﬁned it is

probably ground noise. If the signal remains the same,

or becomes louder, it is likely a metallic target. If you are

still not sure make the hole deeper and repeat

the process.

•A ‘halo eﬀect’, which may be built up around a buried

metal object, makes the object appear to be larger to

the detector than it actually is. This will be reduced

once the target is disturbed from its position in the

ground (e.g. a small object, detected at a substantial

depth, may be more diﬃcult to detect once disturbed

from the ground and lying in the loose dirt. If the object

is re-buried the ‘halo eﬀect’ will not be present).

•Do not try to eliminate what might appear to be a

faint, isolated ground noise by balancing the detector

over the target; you may be ‘balancing out’ the target

response from a deeply buried metallic target. It is

better to Ground Balance around the target, without

going across it, then switch to Fixed and try Pinpointing.

•Dig all target signals, even in previously detected areas.

The GPZ 7000 has superior ground balancing and depth

so it is possible to ﬁnd new targets in well-worked areas

where other detectors have been unable to cope with

Detecting Basics

the high degree of mineralisation and/or salt.

•In some mineralised soils a response may be received

from a concentration of orange/reddish dyke material

or clay. Remember, a metal target will get louder by

moving the coil even centimetres closer.

•If detecting areas of extremely variable mineralisation

detect along the ground contours rather than across

them. This will often stabilise the eﬀect.

•In heavily mineralised areas the operator may need to

sweep the coil 10–20 mm (½”–1”) above the ground.

This should give a more stable Threshold and less

ground noise.

•Very sudden or large changes in the mineralisation of

an area may produce a signal from the detector. Usually

this signal is very broad and often only present in one

direction.

Simple Detecting Exercise

Before attempting to recover real targets, it is important to

understand how to interpret the audio and visual signals

of the detector.

1. Gather a collection of diﬀerent metal objects, e.g.

various coins, gold and silver jewellery, a nail, pull-tab,

brass button and aluminum foil.

2. Take the detector outdoors, away from known

sources of electromagnetic interferences (EMI) and

metal objects.

3. Lay objects in a line, suﬃciently spaced apart to allow

the coil to pass between them. Pay close attention to

the audio signals each diﬀerent target produces.

Pinpointing

Locating the target.

Pinpointing narrows down the location of a buried target,

allowing you to determine its exact location before

digging.

Accurate pinpointing is important to prevent damage to

the buried object, which can signiﬁcantly reduce it’s value.

To ﬁnd a target, and reduce the size of the hole required

to remove it from the ground, it is necessary to pinpoint

the exact location of the target.

To pinpoint a detected target sweep the general area

with the coil taking note of where the strongest signal is

received.

It is important to know that GPZ series coils have two

zones where the target signal is strongest. These are

marked on the coil as two parrallel lines running from the

front of the coil to the back of the coil.

Lines show the strongest signal zones.

By shortening the length of the sweep it should be

possible to draw an imaginary line in the ground where

the strongest signal is located.

Line up the target at 90° from the initial direction and

repeat the process. The object is located where the two

imaginary lines cross.

Target Recovery

Once you have pinpointed the target, it is time to recover

it. During target recovery, it is important to dig carefully

to prevent damage to the buried object, which can

signiﬁcantly reduce it’s value.

It is essential that you carry at least one of the

following digging tools with you while detecting:

•A pick with broad scraping blade (essential)

•A crowbar (for very deep objects in hard ground)

•A small, strong digging spade or shovel (for soft soils,

sand, etc.)

Recovering the Target

1. Clear the area of loose surface material and check

that the target signal is still there. If it is not, the

target should be amongst the moved surface

material.

2. Remember if there are other signals close to your

target.

This is important so when you come to dig your hole

you do not heap the loose dirt on top of another

target already in the ground.

3. If the target signal is still present use your pick to dig

to a depth of approximately 50mm (2”).

Note: When digging, avoid sharp edges to the hole as they

can produce false signals, potentially masking the target.

Slope the edges of the hole to avoid any problems.

4. Sweep the coil over the hole to determine if the

target has been removed. If the target signal is not

heard then the target should be in the pile just dug.

Otherwise dig a little deeper and check again.

5. Start digging approximately 100mm (4”) in front

of the target to reduce the chance of damaging it.

Damaging a coin, relic or gold nugget may reduce its

value.

6. If the target signal disappears from the hole sweep

the coil over the loose dirt and pinpoint its exact

position.

7. Take a handful of the dirt and pass it over the coil.

Note: Your hands and wrists must be free of any metallic

jewellery and watches when passing dirt over the coil.

8. If there is no signal, place the handful carefully in a

new pile, pinpoint the position of the target again,

and repeat with another handful of soil.

9. Once the target is in your hand, transfer half of the

dirt to the other hand. Test each handful of dirt

across the coil.

10. If the target is too small to see drop the dirt onto

the top of the coil and with your ﬁnger move any

suspect objects. A target signal will only be given

when the target is moved.

Note: The GPZ 7000 is a ‘motion’ detector. This means the

coil must be moving over the target, or the target moving

over the coil, in order for the detector to ‘see’ it.

TIP

The GPZ 7000 is very sensitive and recovering

a small target from loose, dry soil takes skill

and patience. A plastic scoop allows you to

pass small amounts of soil over the top of the

coil to check if your target is in it. Carrying a plastic scoop

is a great way to speed up the recovery process.

CAUTION

Back Fill Every Hole You Dig

Always reﬁll any holes, and scatter leaves

and surface debris, before leaving the area.

Help restore the area to its original condition to help give

detectorists a good reputation, and also disguise your

secret hot-spot! Any rubbish you recover should be taken

away with you and disposed of properly.

Reﬁlling holes and removing rubbish will help detector

users maintain a good reputation. This should lead to

more areas being readily accessible for prospecting.

Detector Care and Safety

The GPZ 7000 is a high-quality electronic instrument, ﬁnely engineered and packaged in a durable housing. Taking proper

care of your detector is vital to ensure its ongoing reliability.

WARNING

Please note the following:

•Not all parts of the GPZ 7000 are waterproof.

•Minelab recommends that prior to use, care is taken

to ensure the battery seal (o-ring), the seal seating

groove and the mating face of the battery are

undamaged and kept clean. See “Battery Care and

Safety” on page 38 for instructions on maintaining

you battery.

•O-ring lubricant or grease is not required on

waterproof seals.

•Do not use a petroleum based o-ring grease as it is

likely to damage the waterproof seals.

•Do not leave the detector in excessive cold or heat

longer than necessary. Covering it when not in use

will help protect it. Avoid leaving it in a closed car

trunk or in a car exposed to sunlight.

•Never allow the detector to come into contact with

gasoline or other petroleum-based liquids.

•Avoid getting sand and grit into the shafts or

fastenings (e.g. yoke bolt and cam lock). Do not use

solvents to clean the detector. Use a damp cloth with

mild soap detergent. Wash connectors with distilled

water.

•Hose the detector with clean water after use on the

beach (wading).

•If, through extensive use, the carbon-ﬁbre upper, mid,

or lower shafts become noticeably scored, wipe these

thoroughly with a damp cloth.

•Ensure the coil cable is in good condition and not

subject to undue stress.

•Do not dispose of the battery pack in ﬁre (contact

local authorities for disposal/recycling). Do not

attempt to disassemble or short circuit the battery

pack.

•Take precautions when transporting or storing the

detector. Although the detector is constructed from

the highest quality materials and has undergone

rigorous durability tests, the display screen could be

prone to scratching or serious damage if not treated

with due care.

Battery Care and Safety

To extend battery life:

•Turn oﬀ the control panel backlight; the backlight increases the power consumption by approximately 8%.

•Turn the detector oﬀ when not in use.

•Turn GPS oﬀ when not in use.

•Turn Wireless oﬀ when not in use.

•When using the WM 12, use headphones rather than the speaker; the speaker uses more power than headphones. This

will extend the WM 12 battery life.

WARNING

Please note the following:

•The Lithium-Ion battery is speciﬁcally designed for

the GPZ 7000. Attempting to use the Lithium-Ion

battery pack with other detectors may damage the

detector or the battery pack.

•VERY IMPORTANT: Ensure the battery seal (o-ring),

the o-ring seating groove and the mating face of the

battery are undamaged and kept clean of sand, grit

and other contaminants. To do this:

1. Remove the battery seal with a soft tool. (The

removable seal is in the control box battery

seal groove)

2. Gently brush or wipe out the battery seal

groove and battery mating face avoiding

damage to the surfaces.

3. Wipe over the battery seal using a clean,

moistened cloth.

4. Visually inspect the areas to ensure all sand, grit

or other contaminants have been removed.

5. Reﬁt the battery seal ensuring that it is seated

at the bottom of the groove, is not twisted,

and the corners are aligned.

6. Fit the battery to the detector- take care to

check that the battery sand seal is also free of

dust, grit, and moisture. The sand seal is not

removable.

7. Ensure the battery clips are fully closed.

•Damaged seals or batteries must be replaced.

•Do not try to adapt this battery to other models as it

will very likely cause damage.

•Do not charge the battery at temperatures above

113° F (45° C) or below 32° F (0° C).
