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 ,

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

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 .

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

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

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

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

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

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
