CONGRATULATIONS

Your

new TESORO

metal detector

was

designed

to

provide

you

with

many

happy hours

of enjoyment

on

the

most rewarding

hobby I can

think

of

- treasure

hunting.

Ahead of

you lie fascinating

and

exciting

experiences

as

you

step

into

the

past,

uncovering

artifacts

lost

by

past

generations. I

wish

you

the best

of success.

Your Tesoro

metal detector

is

capable

of

meeting

your

needs

in a wide

range of

treasure

hunting situations.

As

with any

detector,

operator

skill and

familiarity

is

probably

the

limiting

factor

in determining

how successful

you

will be.

We recommend

that

you

read and understand

this

manual fully

before

attempting

to

use

the instrument

in

the field. Then,

as

you

practice

and become

familiar with

your

detector,

your

rate

of

success

will

increase

dramatically.

Your TESORO

metal detector

is a

precision

electronic

instrument,

which

will last for

years

if

properly

cared

for. Treat

it

right and it

won't let

you

down.

Good

Hunting!

GENERAL

INFORMATION

The

Tiger Shark

uses

microprocessor

technology

to create

a

t¡ue dual

function

machine.

In normal

mode

Q\loRM),

The

Tiger

Shark

works

like

any

other

Tesoro detector.

It

uses

the same

gteat

ground balance

and

discrimina-

tion

features

that made

the Bandido

and

Eldorado

series

so successful'

On

land,

the

Tiger Shark

can

be

used

for coin

and

relic

hunting

and even

gold

prospecting.

By

using

the

four

controls

on the

outside,

you

fine tune

your

detector

to

handle

whatever

conditions

you

are

working

in-

we all

know

that

working

in

the wet salt

areas

is different

To

working

in

any

type

of dry

area.

This

is

where

the Tiger

shark

outshines

the land

detectors.

In

land conditions,

the

most crucial

adjustment

is

using

the

ground

balance

to

tune out

mineralization.

In

wet salt

conditions,

changes

in

the con-

ductivity

in the sand

cause

most

of

the

problems.

The

Tiger

shark

uses a

completely

different

set

of

intemal

settings

in

the sALiT

Mode

than

in

the

NORM

Mode.

There

are special

controls

or

techniques

to remember.

When

working

on

a salt water

beach,

just

switch

to SALT

Mode,

adjust

the

Ground

Balance

and

start

hunting.

BATTERY

INSTALLATION

REPLAGEMENT

TIGER SHARK INSTRUCTION

MANUAL

The Tiger

Shark has

been equipped with a

drop-in battery

pack.

To

install

or replace the

batteries, make

sure the detector housing is

dry then

release

the two

draw bolts securing the faceplate

to the housìng.

Gently

pull

the

control

panel

free

bcing carcful not

to twist or strain

the

ribbon

cable

connecting the

faceplate

panel

to the

printed

circuit board.

The Tiger

Shark takes

8 AA size alkaline

batteries. \Mith the

battery

pack

out

of

the

housing, load

batteries

into

the

pack.

Make certain that

you

follow

the

polarity

indicators

on both the

battery holder as well

as batter-

ies

themselves.

Then check the

polarity

of the

pack

as

it

goes

into the hous-

rng.

Look inside the

housing for the two

spring clips and

slide the

pack

so

that

the

battery

terminals

meet the

spring

clips.

There is

only

one correct

way to

put

the

battery

pack

in. If

the batteries are

put

in

wrong, the

detec-

to¡

will not work.

Replace the faceplate

and use the draw

bolts to clamp the

faceplate

back onto the housing.

contacts

should aline with

the battery clips

as shown

GETTING

STARTED

The

pole

length should be adjusted

so that the detector

does

not

become

uncomfortable or

tiring after long

periods

of use. The

detector

grip

should

rest in

your

hand with

your arm relaxed.

your

elbow straight

but

not locked, and with the

pole

extending out

in front of

you

at the

approximate

angle shown

ìn

the

photo.

You should be able to

swing

the detector back

and forth in front of

you

-using

relaxed shoulder

movement

-

while

keep-

ing the searchcoil

as close

to the

ground

as

possible.

This

swinging

movement

is

often called

a

"sweep"

The searchcoil

should

not touch

the

ground

during

your

sweep. The

pole

length

should be

adjusted

to

allow this without

having

to

lift the detector with

your

elbow or shoulder.

The searchcoil should

rest

about one

inch above the

ground

while

you

are

standing

erect.

The angle

of

the

searchcoil

should

allow the bottom

to

be

parallel

to the

ground.

The

pole length

is

adjusted by

depressing the spring

buttons and

extending or shodening

the

pole

until

the

spring

buttons click

into

the

set of

holes

that

give you the

most comfortable

pole

length.

To adjust the searchcoil

angle, simply

loosen the searchcoil

thumb

nut

slightly

and

move the searchcoil

into desired

position. Tighten the

searchcoil

thumb

nut by hand so that the

searchcoil will

hold in

place.

TIGER SHARK

INSTRUCTION MANUAL

The

Quickstart

is designed

to teach

you

how

to

use

your

new Tiger

Shark.

It

provides

a

quick

and

easy means of

learning

your

detector and the

concepts behind

all of the functions.

IMPORTANT NOTE:

The Tiger

Shark

has two very different

modes

of operation.

Normal

(NORM) is

used

for dry

land hunting or fresh

water hunting. Salt Mode

is

for wet salt, sand and

salt water

hunting only. The modes cannot

be inter-

changed.

When

you

switch

nodcs,

you

are actually changing the internal

setup of

your

Tiger Shark.

Please be very aware

which mode

your

detector

is in

while

you

are hunting.

The

controls for the two

separate modes on

your

Tiger Shark operate

almost exactly

the same.

As

you

follow the

Quickstart,

it will be assumed

that

you

are operating in

the Normal Mode. Any

differences between

the

Normal and Salt

Mode will

be

noted. You may want to

go

through the

Quickstart

in

Nolmal

MANUAL

Gheck

and

Set the

lnternal

Gontrols

There are

three controls

that arc

located on

the inside of

the detector.

The

Volume

control,

the Sensitivity

control

and the Threshold control.

All

of

these controls

have been

set at

the factory

for optimum

performance in most

conditions.

Howevet,

if there

is some

neecl to

fine

tune

these controls,

you

will

need to open

the waterproof

casc

to

perform the adjustments.

We recom-

mend

that

you

do

this on a clcan

dry surface

(a

clean beach

towel that

is

spread

out will

do fine).

When

you

are done

with adjustments,

visually

inspect

both

the control

box

and

l'ace

plate

O-ring,

as

it may

cause

leaks.

When

you

open

the detector

case,

it will release

the batteries

from the

contacts and

cause

the detector

to stop functioning.

While

you

are

making

adjustments,

it will be ncccssary

to

place

a slight

pressure

on

the battery

pack

to make

the detector work.

When

you

recorutect

the batteries

to the contacts,

the automatic battery

test

will be

heard. Once

the case

is

open,

reach over

the

top of the

detector with

your left hand

(right

if

you

are

left handed) and

gen-

tly

press

the

batteries

onto the contacts.

Use

your

f,rne

jewelers

screwdriver

to adjust

the

potentiometers inside

the case.

If

you

would

like

to

set

the

intemal controls,

please

continue

with

this

section

of the

Quickstart.

If

you

would

prefer not to set the

intelnal controls,

please

switch

the

scctiott,

the threshold

is a slight steady

tone

that is used

as

a reference

point to

jutlgc

targets by.

Some

targets

may be small

enough

or deep

enough

that thcy

will

not be

able to

generate an audio

signal

by themselves.

By

monitoring

a

threshold,

you

already

have a signal

so that

changes

in that signal

will bc cas-

ier to hear.

However,

if the

threshold

is set too

loud or

too soft,

small

changes

in the signal

will be

hard to

hear. To

of ignoring

and

hum until

The ALL

MET circuit

uses

a singlc

channel

to detect

various

metals.

The

MOTION

DISC

circuit

uses

twO

cliflbrcnt

channels,

that amplihes

and

filters

the signals,

and

then

compares

the twcl

to

determine

whether

or

not

to beep

atalarget.

while

this

is

a

grcat advantagc

for

ignoring

unwanted

targets.

it

can

make

the circuitry

more

susceptible

to interference.

A

number of

outside

conditions

such

as

power lines,

highly

nrineralized

soil

and

wet salt

sand can

cause

interference.

The

Sensitivity

control

is used

to raise

or

lower

the

power

to the operationat

amplificrs,

which changes

the

gain.

Gain

is the

measure-

ment

of how

much

a signal

is

amplihed.

The higher

the

gain,

the more

depth

and sensitivity

to small

objects

a detector

has.

Unfortunately,

any

small

inter-

ference

that

is amplifred

can

cause

the

detector

to

become

erratic.

The

Sensitivity

control

is

used to

find

the best

gain

setting

in any

location

with-

out

letting the

detector

becomc

unstable.

Turn

With

the case

open,

place a

slight

pressure on

the battery

pack and

wait

for

the battery

test

to finish.

When

the battery

test

is done,

you will

not

hear

any sounds

in

your headphones

until

you

pass

a

target

in

front of

the

coil. Using

you

screwdriver

turn

the

potentiometer

clockwise

to increase

the

gain and counterclockwise

to

decrease

the

gain. Take some

time

to try wav-

ing targets

in front

of the

coil

with different

sensitivity

settings.

Notice

that

with

a higher

sensitivity

setting,

the

farther

away

from the coil

a

target can

be

and still

get

a response.

Please

note

that

your

detector

will

probably

"chat-

ter"

at maximutn

sensitivity.

This

is normal

and

will not

hurt

your

detector.

The best

setting

is

to set

the Sensitivity

control

to

a

point

just

before

the

detector starts

to chatter.

GETTING

STARTED

Perform Air Test

in MOTION

DISG Mode

As discussed

before,

the Discriminate

Mode

is used

to filter unwanted

targets from

good

targets.

The

principle

behind

this

is

pretty

simplc.

Thc

detector

sends out a signal

and

then receives

it back creating

a

small

electron-

ic

field. As

metal

passes

through

the

field that the detector

generates, it

catts-

es a change

in the received

signal.

The amount

of change

that

each typc of

metal causes

is fairly constant:

therefore,

we can

tune our detectors

to miss

the targets

that we don't

want to find.

The change

is based

on

the type of con-

ductivity

that each

target has.

the

general list

of

conductive

targets is as

fol-

lows: iron, foil,

nickels,

gold

jewelry

pull

tabs, screw

caps,

pennies

and sil-

ver coins

- starting

with dimes

and working

up to

silver dollars.

This

list is

meant to be a

guide

only.

There

is

a

point

that some

gold

rings and some

pull

tabs overlap.

Also,

the

depth

of

the target and

its orientation

in

the

ground

can

change

the received signal.

A

coin

that

is flat to the coil

will

produce

a bet-

ter signal

than a coin

that is on

edge. Take

some time

nolv to

try diffelent

combinations

of depth

and orientation

of

your

tagets

and

hnd out how

your

detector

responds.

We are

now ready

to

discriminate

targets

from each other

. We will

start

with

the

DISC LEVEL at

zero. Wave

the targets

one at

a time at

least

2-l

12

inches away

from the coil.

All

four targets

(the

iron,nickel,

pull tab and

quar-

ter) will

respond with a

good

audio

signal.

Next, we

will turn

thc

DISC

LEVEL

up to approximately

3 or

4

(2

or

3 in the SALT

Mode).

This shoulcl

be

high enough

to knock out

the

iron target

and still

get

a

positive

rcsponsc

on

the nickel,

pull

tab,

and

quarter. When

you

are done

with the

iron target,

turn

the

DISC LEVEL to approximately

6 or

7

(4

or 5in

the

SAIT

Mode).

This level

is high enough

to knock

out

the nickel.

At this time

the iron

target

and

the

nickel should

give

no

response,

while the

pull

tab and

quarter

will

give

a

solid

response.

Next,

turn the

DISC LEVEL

to approximately

7

-ll2

to

8-112

(7

or 8

in

SALT

Mode).

At this

time

only

the

quarter

should

respond

with

an audio

signal. Now

roll the

DISC

LEVEL all

the way to

MAX. Notice

that the

quarter is

still

responding.

The discrimination

will not

go

high

cnough

to lose most silver

coins.

This air

test

was

designed

to show

you

how

the MOTION

DISC

Mode

works.

Each machine

may

be

a

little

different

than all the others,

so

you may

want to take

some time

and try different

targets

to find

the responses

of

your

machine.

At a

later

date,

you may also build

a test

garden

to

test

your

detec-

tor in

the f,reld.

Gonclusion

Congratulations,

you lravc

lust

fìllishcd

the

Quickstart

for

your new

Tiger

Shark

metal

detector

and in

tltc

proccss have

learned

quite

a

lot about

your

detector.

But experience

is tlrc best

teacher.

I would

recommend

that

you

get

out

and

practice with

youl

clctcctor

as

much as

possible. Any time

spent

using

your detector

will

givc

you

valuable

experience.

Now

that

we have

gonc tlrrough

the

Quickstart,

you

are

now

ready

to

take

your

Tiger

Shark

out

and lcarn

how

to

ground

balance.

(NOTE:If

you

have not

gone through

the Tiger Shark

Quickstart,

it is

strongly

recommend-

ed that

you

do so

before

ground balancing

your Tiger Shark.)

OPERATING

TECHNIQUES

Ground

balancing

your

Tiger Shark

Glound

balancing

is a

simple

but very

imporlant skill that

you

nrust

mas-

ter to

get

the

most out of

your

detector.

The Tiger Shark

has controls that

will

allow

you

to tune the

detector to the exact

ground

matrix that

you

arc

hunt-

ing in. Finding and

maintaining the exact

tune or balance

will

give you

the

highest

possible

depth and stability

for

you

conditions. Once

you

have

read through this section,

it is most

important

that

you

get

out and

prac-

tice

your ground

balancing skills

as

often

as

possible.

To

start,

find

an

area that is free

of metal targets,

If

your

coil is over

any targets, it will

always

give

a

positive

signal and

it will

be

impos-

sible to correctly

ground

balance

your

detector. Start

with

your

Tiger

Shark

in ALL MET FAST

position

(You

can

use the

ALL MET

SLOW

Position,

but it will

take a little

longer to do

your ground

balance.)

At this time,

it

will

not matter where

your

GROLIND

ADruST

knob is

set.

Place

your

DISC LEVEL at

min

and switch

the MODE switch

to

NORM.

After the battery

test is

done,

you

are ready to begin

the

ground

balance

procedure.

(NOTE:

Unless

you

are on a

wet salt beach,

do not use SALT

Mode. It will

not

ground

balance

to normal condi-

tions.

The

SALT

Mode is to

be used

only on a

wet

salt

beach).

Lift

your

detector straight

offof

the

ground

about 6

to 8 inches.

Keep the coil

parallel

to the

ground.

Lift

your

detector Straight

off of

the

ground

about 6 to I

Keep

the

coil

You must

lift

your

up.

Do NOT swing

it like a

thc tlotector

will reacl

the

you

know

how to adjust

to achicve

a

(NOTE:

You

must lift

your

Once

you

have

got

a steady

quickly lowcr

thc coil straight

down

to

approximately

I

inch offof

the

ground

and

listen

to any change

that

may occur

in the

thresh-

old. You will

hear

one

of

the

three

sounds:

OPERATING

TECHNIQUES

I9

Just

like

any skill,

ground

balancing

must be

practiced

constantly.

The

casiest

place

to do

it is in

your

backyard or

anyplace close

that has at

least a

l0 foot

by

10

foot

area.

First,

check

for

any

metal targets and

remove them.

When

the

area

is

clean,

take

your

Tiger

Shark

and

ground

balance

it. When

you

are done,

turn the

GROI-IND

ADruST

knob either

positive

or

negative

and

ground

balance again. Keep up

this

practice until

you

feel

comfortable

with

ground

balancing.

Take

some

time to

keep

your ground

balancing

skills

sharp and

you

will see better

results in the f,reld.

Pinpointing

The

sweep speed

of the detector

is low enough

to allow

pinpointing

in the

Motion Discriminate Mode but will

require a little

more

practice.

Move the coil slowly

from side to side and

then from

front to back over

the

target.

Raising the coil slightly

and slorving

the sweep speed

will

naffow

down

the detection area

enough that it's easy

to tell whe¡e

the coil center

is

at the instant of sound.

Another easy

method is to sweep

the coil from side

to side across

the tar-

get in

very short sweeps

as

you

slowly

move

forward and backward

across

the target.

Slow

down

the

sweep

rate and shorten

the

sweeps

until

you

just

barely

get

a

response at

one spot.

The target

will

be directly below

the coil

center at

this response

time.

The easiest way

to

pinpoint

for most

people

will be

to

switch

to

the ALL

MET

Mode, since

no-motion is required.

To

pinpoint

a

target that doesn't

sat-

urate the audio,

just

move the coil forward

and back

and

side

to side until

you

get

the

strongest

sound.

The target will be directly

below

the

coil

centcr.

If

tlre andio saturates over

a

large area,

simply

hold the coil over

the

target

momentarily

to

detune

the

detector.

This will

narrow its field of

response

to

allow

you

to once

again seek

the area

ofsfongest

response.

Planting a Test

Garden

To better learn how

your

detector

performs in

the freld, it is helpful

to bury

some coins

and hash

metal

junk

items in an

afea that

you know is clear of other

metal

objects, and

then try the Tiger Shark

in the all metal

& discrimrnate

modes.

Check the area

in the all

metal mode to

be

swe

it's

clear

of trash.

Then bury the

targets

at

least I foot apart

and from 2

to 4 inches deep

to

start.

Make a

map of

the arca to

be

sure

you

know what each

target

is

and

how

deep

it is. Practice on

these targets to familiarize

yourself

with

your

detector's

target response.

This will

also help

you leam the

proper

sweep speed

for

best

operatìon.

This

type

ofprac-

tice area is often called

a

"test

garden" or "test bed"

and is one of

the best tools

to help

you

develop

your

metal detecting skills.

1)

the threshold

will

get

louder

or

go

positive,

2)

the threshold

will

go

quiet

or

become

negative, or

3) the

threshold

will stay

the same.

If the threshold

stays

the same,

the

detector

is

telling

you

that

the

ground

matrix

is not

affecting it

and

you

are

ready to

hunt.

If

you get

a

positive

or

negative sig-

nal, the

machine

is

telling

you

that

it

is being affected

by

the

ground

matrix and

must be

adjusted

for

peak

performance.

Ifyour

threshold

goes positive,

you

must turn

the GROLIND

ADJUST

knob counterclockwise

or

towards

the

negative side.

If

your

threshold

goes Negative,

You must turn

the GROI-IND

ADruST

knob clockwise

or towards

the

positive

side.

Once

you

have made

an adjustment,

lift the

coil up,

let the threshold

retune and

push

the coil

down

again

while

listening for any

sound

change as

the coil

drops.

Ifthere is

a threshold

change,

follow

the

above directions

and

repeat until

you

have

very

little or

no threshold changes

on

the way

down.

Avery

slight

positive response

is better

than any

kind ofnegative

response.

If there

are threshold

changes

on the upstroke,

do

not

pay

attention to

them. As

you

raise

the coil,

the detector

goes

from a

ground matrix

(soil) to

no

ground

matrix

(air) and

that difference

will

most

likely cause some

change

in the thleshold

tone.

Only

changes

on the

down stroke

are

to be

adjusted

for.

Now that

your

detector

is

ground

balanced,

you

are

ready to

hunt. You

can stay

in

either

of

the ALL

MET

Modes or switch

into

the MOTION

DISC.

Whichever

mode

you

choose

to

hunt in,

it is always

necessary

to

ground

balance

in

ALL MET

Mode

frrst.

Once

you

have

got

a

steady

threshold,

quickly

lower the coil

straight

down

to approximatelY

1

inch off the

ground.

AND USE

22 TIGER SHARK

INSTRUCTION MANUAL

Basic

Gare

The

Tiger Shark is a sturdy

instrument, but it

is not desigaed

to

with-

stand

abuse. In caring for

your

Tiger

Shark,

there are several

important

"DO

NOTs"

to remember. DO NOT use it

to

pry

rocks loose or

to

beat

bushes out

of

the way.

DO

NOT store

it in

places

t.hat

can

get

extremely

hot

(next

to a

woodstove,

in an attic). DO

NOT leave it in

the trunk

of

a

car or

in

the

back

of a hatchback-style

car where

high temperatures can

build up. DO NOT

store

it with

the

batteries

installed as batteries

may leak. DO

NOT spray

lubricants such as WD-40, or

any type of cleaners,

solvents, sealants or

other chemicals

into or onto

the

electronic

parts,

switches,

or controls.

And

finally,

DO NOT attempt to

modiff or

repair the detector's electronics

as

this will

void

your

detector's warranty.

THE WARRANW DOES

NOT

COVER

DAMAGE

RESULTING

FROM AN ACCIDENT

NEGLEGT

OR ABUSE.

Protecting

your

investment

Often

detectorists

are disappointed

when

their

new detector

slowly

becomes

less and less responsive and seelns

to

have lost

sotne

of its origi-

nal

peak

performancc.

You can

help avoid

this from happening

to your

detector by

following these basic

care and

protection

guidelines:

Ø

Operate

your

detector exactly as recontmended

in this operator

instruc-

tion manual.

EI

Use

only high-quality alkaline

batteries of the

correct voltage.

Never

substitute

a different voltage.

.When

using a

Ni-Cad battery, always use

a separate convertible

pack

with

the

proper

voltage ouþut

for the detec-

tor's design.

Ø

Remove the batteries

from the detector

after

each

use. This will

prevent

damage

to the

detector

if the batteries

leak.

Ø

ttre

searchcoil

cable is

hard-wired to the searchcoil

and

protected

by a

strain relief.

It is very important that

the strain relief temains

intact and

should

never be adjusted or

tampered with

ø

GENERAL INFORMATION

Keep

cables

properly

wound

around

the pole

stems and protect

them

during

use. Floppy, pinched,

or

cables that become

snagged during

use

may short,

causing erratic noises

or unnecessary

replacement

of the

searchcoil.

Sweep

the searchcoil

carefully, especially

when using

around rocks

and

building foundations.

Avoid hitting

the

searchcoil against hard,

solid

objects and surfaces.

Keep

your

searchcoil

slightly off the

ground

during the

sweep, espe-

cially

when using in

gravel

or hard, rocþ

dirt.

Always

use a

properly

designed

protective

scuff cover

on the search-

coil.

(See

"Optional

Accessories"

on the

page

25.)

Remove

and

clean out scuff covers

periodically

to avoid

buildup

of

mineralized

dirt

paficles

which will

affect

performance.

The

searchcoil is waterproof

and

can be submerged in

either fresh

or

salt water. After

the searchcoil is

used in

salt wate¡ ri¡se it

and the

lower

stem assembly

well with fresh

water to

prevent

corrosion.

The entire

unit is

waterproof, but thoroghly

dry the enti¡e

unit before

taking

off

faceplate.

Ø

After

each use,

clean

the

detector with a

soft cloth to remove

dust,

moisture,

or other contaminants.

When transporting

the

detector in a car

during hot weather,

store

it

on

the floor of the

passenger

compartment

if

possible.

Using a carry

bag

gives

additional

protection.

In any

case, never allow the

detector to roll

around

unprotected in the trunk

or

back ofa

pickup

truck.

Protect your

detector fiom

dust, moisture, and

extreme temperatules

during storage.

When

shipping,

use the original

factory carton

or similar heavy-duty

container and

provide

a minimum

one inch

of

padding

around all

parts.

Treat your

detector as

you

would

any sensitive electronic

instrument.

Though

ruggedly constructed and

designed to

withstand the

demands

of normal treasure

hunting,

proper

care is essential.
