°

When

searching

in

highly

mineralized

area,

the

unit

will

sound

even

if

there’s

no

metal.

In

this

case,

you

can

lower

the

sensitivity

and

increase

the

height

between

the

search

coil

and

the

ground

until

the

false

signal

disappears.

If

necessary,

reset

the

DISC.

°

When

searching

in

trash

area,

it’s

better

to

set

the

DISC

to

11:00

position,

so

that

the

unit

can

notch

most

of

invaluable

metals

such

as

nails

and

small

trashy

iron.

°

Move

away

any

metal

digging

tool

when

searching.

°

Sensitivity

level

is

generally

in

contradiction

with

that

of

the

Discrimination.

The

higher

the

sensitivity

level

is,

the

worse

discrimination

will

be.

But

you

can

lower

the

sensitivity

to

have

better

discrimination.

CARE

AND

MAINTENANCE

Your

metal detector

is

an

example

of

superior

design

and

craftsmanship.

The

following

suggestions

will

help

you

care

for

your

metal

detector

so

you

can

enjoy

it

for

years.

Handle

the

detector

gently

and

carefully.

Dropping

it

can

damage

circuit

boards

and

can

cause

the

detector

to

work

improperly.

Use

the

detector

only

in

normal

temperature

environments.

Temperature

extremes

can

shorten

the

life

of

electronic

devices,

causing

internal

damage

to

the

detector.

Keep

the

detector

away

from

dust

and

dirt,

which

can

cause

premature

wear

and

tear

of

parts.

Wipe

the

detector

with

a

damp

cloth

occasionally

to

keep

it

looking

new.

Do

not

use

harsh

chemicals,

cleaning

solvents,

or

strong

detergents

to

clean

the

detector.

to

the

Search

Coil

Sweeping

Hints:

¢

Never

sweep

the

search

coil

as

if

it

were

a

pendulum.

Raising

the

search

coil

while

sweeping

or

at

the

end

of

a

sweep

will

cause

false

readings.

°

Sweep

slowly

hurrying

will

cause

you

to

°

It’s

better

you

sweep

the

search

coil

from

side

to

side

in

an

arc

line

of

3

inches

motion

and

keep

the

search

coil

parallel

with

the

ground.

Factors

That

Affect

The

Detecting

It’s

difficult

to

have

an

accurate

detecting

result.

It

takes

practice

to

get

better

detection

results.

Sometimes

the

detecting

may

be

restricted

by

some

factors.

°

If

there

are

interference

from

other

instruments

or

electrical

cable,

TV

or

radio

in

your

searching

area,

lower

the

sensitivity,

or

to

change

the

current

searching

area.

TESTING

AND

USING

THE

DETECTOR

This

metal

detector

has

two

operation

modes:

ALL

METAL

&

DISC.

ALL

METAL

-

is

used

to

find

all

kinds

of

metal

targets.

DISC

-

Is

used

to

discriminate

the

metal

type.

Set

the

operation

mode

to

ALL

METAL,

DISC

to

counter

clockwise

end,

SENS

to

high

position.

Then

hold

the

search

coil

parallel

with

the

ground

about

5-2

inches

/

1-5cm

above

the

surface.

Sweep

the

search

coil

from

side

to

side

in

an

arc

line

of

2.75

inches

/

7cm

motion.

When

the

detector

detects

a

buried

target,

it

sounds

a

tone.

Make

a

visual

note

of

exact

spot

on

the

ground

where

the

beeps.

Then

stop

LISTENING

SAFELY

To

protect

your

hearing,

follow

these

guidelines

when

you

use

earphones.

°

Set

the

volume

to

the

lowest

setting

before

you

begin

listening.

°

After

you

begin

listening,

adjust

the

volume

to

a

comfortable

level.

°

Do

not

listen

at

extremely

high

volume

levels.

Extended

high

volume

listening

can

lead

to

permanent

hearing

loss.

°

Once

you

set

the

volume,

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.

Traffic

Safety

DO

NOT

wear

headphones

while

operating

your

detector

near

high-traffic

areas.

Even

though

some

earphones

are

designed

to let

you

hear

some

outside

sounds

when

listening

at

normal

volume

levels,

they

still

can

present

a

traffic

hazard.

Cautions:

°

Use

only

fresh

batteries

of

the

required

size

and

recommended

type.

°

Always remove

old

or

weak

batteries;

batteries

can

leak

chemicals

that

can

destroy

batteries

promptly

and

properly.

You

can

extend

battery

life

by

using

earphones,

which

require

less

power

than

the

built-in

speakers.

USING

EARPHONES

You

can

connect

a

pair

of

headphones

(not

supplied)

to

the

detector

so

you

can

listen

privately.

Using

also

saves

TESTING

AND

USING

THE

DETECTOR

This

metal

detector

has

two

operation

modes:

ALL

METAL

&

DISC.

ALL

METAL

-

is

used

to

find

all

kinds

of

metal

targets.

DISC

-

Is

used

to

discriminate

the

metal

type.

Set

the

operation

mode

to

ALL

METAL,

DISC

to

counter

clockwise

end,

SENS

to

high

position.

Then

hold

the

search

coil

parallel

with

the

ground

about

5-2

inches

/

1-5cm

above

the

surface.

Sweep

the

search

coil

from

side

to

side

in

an

arc

line

of

2.75

inches

/

7cm

motion.

When

the

detector

detects

a

buried

target,

it

sounds

a

tone.

Make

a

visual

note

of

exact

spot

on

the

ground

where

the

detector

beeps.

Then

stop

the

search

coil

directly

over

this

point

on

the

ground.

Move

the

search

coil

10

straight

forward

away

from

you

and

straight

back

towards

you

a

couple

of

times.

Meantime

slowly

rotate

the

DISC

control

clockwise

away

from

ALL

METAL

until

the

unit

does

not

sound

or

sounds

short

tone.

You

can

identify

what

kind

of

metal

is

detected

according

to

the

setting

position

of

DISC.

A

reference

for

you

to

know

what

kind

of

metal

is

Search

Coil

Sweeping

Hints:

¢

Never

sweep

the

search

coil

as

if

it

were

a

pendulum.

Raising

the

search

coil

while

sweeping

or

at

the

end

of

a

sweep

will

cause

false

readings.

°

Sweep

slowly

hurrying

will

cause

you

to

miss

targets.

°

It’s

better

you

sweep

the

search

coil

from

side

to

side

in

an

arc

line

of

3

inches

motion

and

keep

the

search

coil

parallel

with

the

ground.

Factors

That

Affect

The

Detecting

It’s

difficult

to

have

an

accurate

detecting

result.

It

takes

practice

to

get

better

detection

results.

Sometimes

the

detecting

may

be

restricted

by

some

factors.

°

If

there

are

interference

from

other

instruments

or

electrical

cable,

TV

or

radio

in

your

searching

area,

lower

the

sensitivity,

or

to

change

the

current

searching

area.

°

When

searching

in

highly

mineralized

area,

the

unit

will

sound

even

if

there’s

no

metal.

In

this

case,

you

can

lower

the

sensitivity

and

increase

the

height

between

the

search

coil

and

the

ground

until

the

false

signal

disappears.

If

necessary,

reset

the

DISC.

°

When

searching

in

trash

area,

it’s

better

to

set

the

DISC

to

11:00

position,

so

that

the

unit

can

notch

most

of

invaluable

metals

such

as

nails

and

small

trashy

iron.

°

Move

away

any

metal

digging

tool

when

searching.

°

Sensitivity

level

is

generally

in

contradiction

with

that

of

the

Discrimination.

The

higher

the

sensitivity

level

is,

the

worse

discrimination

will

be.

But

you

can

lower

the

sensitivity

to

have

better

discrimination.

CARE

AND

MAINTENANCE

Your

metal detector

is

an

example

of

superior

design

and

craftsmanship.

The

following

suggestions

will

help

you

care

for

your

metal

detector

so

you

can

enjoy

it

for

years.

Handle

the

detector

gently

and

carefully.

Dropping

it

can

damage

circuit

boards

and

can

cause

the

detector

to

work

improperly.

Use

the

detector

only

in

normal

temperature

environments.

Temperature

extremes

can

shorten

the

life

of

electronic

devices,

causing

internal

damage

to

the

detector.

Keep

the

detector

away

from

dust

and

dirt,

which

can

cause

premature

wear

and

tear

of

parts.

Wipe

the

detector

with

a

damp

cloth

occasionally

to

keep

it

looking

new.

Do

not

use

harsh

chemicals,

cleaning

solvents,

or

strong

detergents

to

clean

the

detector.
