T ARGE T DEPTH
T he devic e pr o vides an estima t ed tar get depth ac c or ding t o the sig nal str ength both
dur ing det ec tion and in the pinpoin t mode .
Depth I ndica t or: I t sho w s the tar get's pr o ximit y t o the sur fac e in 5 lev els dur ing det ec tion.
B ecause each mode of the G old K ruz er has diff er en t depth, the depth indica t or will displa y
a diff er en t depth lev el f or the same tar get in diff er en t modes .
I n the pinpoin t mode , estima t ed tar get depth is sho wn on the displa y in cms (or inches -
please see belo w f or details) while getting closer t o the tar get .
D epth det ec tion is adjust ed pr esuming tha t the tar get is 2.5cm (1'') in diamet er . A c tual
depth v ar ies ac c or ding t o the siz e of the tar get . F or instanc e , the det ec t or will indica t e mor e
depth f or a tar get smaller than 2.5cm (1'') and less depth f or a lar ger tar get . I n r ealit y ,
pinpoin t pr oc edur e is not in t ended f or depth det er mina tion but e xac t loca tion

IMPOR T ANT! I f y ou w an t the tar get depth t o be displa y ed in inches inst ead of cms please
do the f ollo wing: W hile the devic e is off , pr ess and hold the SE T TINGS/OPTIONS and
BOOST butt ons simultaneously and tur n the devic e on. ''I n '' will be displa y ed . T o swit ch

L ARGE OR NEAR-SURF A CE T ARGE T S
T ar gets which ar e near the sur fac e ma y g iv e multiple diff er en t sig nals t o the devic e . I f y ou
suspec t a tar get near the sur fac e , lif t the sear ch c oil and swing it mor e slo wly un til a single
sig nal is r ec eiv ed . A lso , if ther e is a lar ge tar get near the sur fac e it ma y cause an o v er load in
the sear ch c oil and the devic e star ts t o gener a t e a c on tinuous sound which r esembles a
sir en. “ O v er load ” message is sho wn on the displa y simultaneously . I n such a case , lif t the
sear ch c oil up un til the message disappears .
F ALSE SIGNALS AND REASONS
S ometimes , the devic e ma y pr oduc e sig nals which ar e similar t o a tar get sig nal although no
metal tar get is pr esen t . T her e ar e v ar ious r easons f or the false sig nals r ec eiv ed b y the
devic e . T he most c ommon ones ar e g r ound miner aliza tion or r ocks with high miner al

rust ed or c or r oded ir on or f oil in the soil , gain or thr eshold v alues set t oo high.
Sur r ounding elec tr omag netic sig nals can be elimina t ed b y r educing the gain. I f another

M A GNE TIC MINER ALIZ A TION INDIC A T OR
T he M ag netic M iner aliza tion I ndica t or c onsists of 5 lev els . T he indica t or bars do not r ise a t

T his measur emen t is impor tan t fr om t w o aspec ts . F irst , on g r ounds with high mag netic
miner aliza tion, sear ch depth is lo w and users should be a w ar e of this fac t . S ec ond ,
mag netic miner aliza tion is a pr oper t y which is par ticular ly seen with miner aliz ed r ocks and

ROCKS AND SEARCHING IN ROCK Y TERR AINS ( GENER AL MODE AND O THERS)
Challeng ing g r ound c onditions ar ise especially when c onduc tivit y and mag netic
pr oper ties of the g r ound ar e t oo in t ense . Oper a tion of the devic e o v er such g r ound is made
possible b y selec ting the best oper a ting mode as w ell as using pr oper g r ound balanc e ,
gain, iSA T , iM ASK and thr eshold settings .
S t ones and r ocks or ca vities inside the g r ound ar e as impor tan t as the g r ound itself in
r egar ds t o the sear ch and tar get det ec tion qualit y .
S oil and r ocks ha v e t w o diff er en t pr oper ties just like the tar gets y ou ar e sear ching f or . One
of them is the in t ensit y and the other one is the c onduc tivit y - mag netic per meabilit y r a tio
and these t w o pr oper ties ar e independen t fr om each other . I n this manual , the
c onduc tivit y - mag netic per meabilit y r a tio will be r ef er r ed t o as ID in shor t . H igh mag netic
per meabilit y , lo w c onduc tivit y r esults in lo w ID . S oil or r ocks can be highly per meable and
ha v e lo w or high IDs as w ell . I f the c onduc tivit y incr eases r ela tiv e t o mag netic per meabilit y
then the ID will also incr ease .
Hot r ocks ar e classified as nega tiv e or positiv e based on their ID being lo w or high in
c ompar ison t o the ID of the soil they ar e in. One or both of the t ypes ma y be pr esen t in a
field . T he nega tiv e and positiv e eff ec ts men tioned her e will only be v alid if g r ound
balancing is pr oper ly done on the e xisting g r ound . O ther wise , soil itself will not ac t
diff er en tly fr om hot r ocks in t er ms of ID . I n '' TR A CKING'' ho w ev er , c onditions will diff er .
T her ef or e , the eff ec ts of r ocks in tr ack ing will be discussed separ a t ely . Her e w e ar e r ef er r ing
t o a pr oper g r ound balanc e without tr ack ing .
P ositiv e hot r ocks ac t just like metal and pr oduc e a metal sound . I n the G ener al S ear ch
M ode ( GEN) they pr oduc e a “ zip zip ” sound when the sear ch c oil is mo v ed o v er them. I f the
sig nal is str ong enough, the devic e ma y pr oduc e an ID f or these hot r ocks and the M iner al
Bar will r ise . Nega tiv e hot r ocks in the G ener al S ear ch mode , pr oduc e a long “ boing ” sound
when the sear ch c oil is mo v ed o v er them. T he devic e does not g iv e an ID f or these hot r ocks
ev en if the sig nal is str ong but the M iner al Bar will r ise .
P ositiv e hot r ocks pr o vide a t ypical metal sound in the other modes . Nega tiv e hot r ocks do
not pr o vide a sound in these modes (e x c ept f or r ar e cases of false sig nals). T he M iner al Bar
will r ise in either case .
A t higher settings of iSA T , ther e will be no change in the sounds of positiv e or nega tiv e hot
r ocks . A s the iSA T v alue is decr eased , the sound of positiv e hot r ocks will r emain the same
but the nega tiv e hot r ocks ma y g iv e a thinner beep sound inst ead of the boing sound .
T her ef or e , y ou can make a decision b y list ening t o the audio r esponses pr oduc ed b y the
devic e in the field . I n the GEN mode , when the devic e pr oduc es an audio t one , if the miner al
bar r ises a t the same time , y ou can decide whether the tar get is a positiv e or a nega tiv e hot
r ock b y list ening t o the sound . I n the other modes , if y ou ha v e not changed the default
DISC. setting of the de vic e , the devic e will not pr oduc e an audio t one f or positiv e hot r ocks
and if y ou ha v e g r ound balanc ed , it will not emit an audio t one f or nega tiv e hot r ocks
an y w a y . I f y ou ha v e changed the DISC. setting of the devic e in these modes , when y ou
r ec eiv e a str ong sig nal and a stable ID , y ou can distinguish if the det ec t ed tar get is a positiv e
hot r ock or metal b y check ing the ID . Ho w ev er , r emember tha t w eak sig nals ma y pr oduc e
diff er en t IDs and metals under r ocks ma y pr oduc e diff er en t metal sig nals . T her ef or e , the
most appr opr ia t e ac tion is t o dig up when a metal sig nal is r ec eiv ed .
B ecause y ou can enc oun t er such a situa tion in gold pr ospec ting ar eas wher e nuggets ar e
being sear ched f or , it is impor tan t f or y ou t o get familiar with the hot r ocks and their IDs in
y our sear ch field and pr e -t est the devic e with some nuggets .
I f y ou ar e using one of the modes other than the GEN mode and y ou k no w the ID of the
sur r ounding hot r ocks , y ou can use the DISC. setting t o elimina t e the r ocks . Ho w ev er , this
ma y not be sufficien t t o a v oid all r ock sig nals . T he devic e ma y still r ec eiv e sig nals fr om r ocks
because soil and r ocks t ogether will f or m a c ombined eff ec t and gener a t e a diff er en t ID
than those of r ocks .
TR A CKING AND EFFEC T S OF ROCKS
W hen the tr ack ing is ac tiv e , the devic e ma y g iv e an audio r esponse and ID when it passes
o v er a hot r ock because the eff ec t of the r ock will be diff er en t than the g r ound's . A t the sime
time , the miner al bar will r ise . I f y ou swing the sear ch c oil o v er the r ock , tr ack ing will
aut oma tically adjust the setting and the audio r esponse/ID will either disappear or
diminish sig nifican tly . B ecause ther e is a sligh t dela y in tr ack ing , y ou ma y hear a str ong
sig nal a t the first one or t w o swings un til the setting is adjust ed . T hen the sound will get
w eaker and disappear . T his will not happen with metal tar gets because metals will pr ev en t
the devic e fr om g r ound balancing . T her ef or e , in tr ack ing , if y ou ar e getting a c onstan t
sig nal o v er a tar get af t er r epea t ed swings , ther e is a high possibilit y tha t the tar get is a
metal . M o ving fr om o v er a r ock back t o soil , the devic e ma y g iv e sig nals t o the g r ound f or a
f ew swings un til the g r ound balanc e setting is upda t ed again. T his is nor mal and should not
mislead y ou .
T r ack ing is not r ec ommended t o elimina t e r ocks under nor mal c onditions . I t is
r ec ommended f or use in ar eas with chang ing soil t ypes .
ME T ALS UNDER ROCKS
G old K ruz er incr eases the possibilit y of det ec ting metal tar gets under miner aliz ed r ocks
