1. Asse mbling of the devi ce:
The bearing rod i s asse mbled b y i nser ting of the lower part into the upper
one. Choo se the d esired lengt h of the whole co nstructi on and the f ixing cla mp
is tightene d betw een both part s of the bearing r od. The lower p art of the
bearing rod is put with the o pening b etween the e ars of the coil an d the p lastic
bolt is tightened b y choo sing the p osition of the coil to be parallel to the
ground surf ace. The coil cable mus t be wind up tightl y around the bearin g rod
and is switch ed to the socket of the b ox with electr onic. Upon switc hing o f the
3
cable of the coil to the socket on th e box, tighten the well the metal nut of the
coupling to the t erminal of the box. Upon switchin g off , unscrew the nut
co mpletel y and pu ll out t he co uplin g witho ut pul ling or twisti ng th e ca ble of
the coil. This wa y, yo u will prev ent the cable and the conductors i n it f rom
breakdown or short circuit.
The searching coi l is approached to t he surf ace of earth b y pa yi ng attenti on to
avoid prese nce of met als within its r ange.
NOTE: Detect or ma y not work a s ex pected ind oors du e to the high degr ee of
met als used in mo dern construc tion. It is best to tune a nd practice out doo rs to
ensure stabl e, pred ictable r esul ts.
2. Sw itch on and w ork w ith NRG 1 50.
1. Turn the “ ON / VOLUM E ” knob to “ ON” and a dju st pref erenc e volu me of
sound. The displa y w ill mo mentaril y s how an o penin g screen whi ch lis ts the
sof tware version.
2. Settin g the “T HRESH OLD ” - While holdi ng the d etector a f ew f eet above
ground and aw a y f ro m an y metal o bj ect, slowl y tur n th e “THRESHOLD ” knob
until yo u hear a ve r y slight audio ton e through the spea ker or h eadphon es. This
is the opti mu m se t -point f or the “T HRESH OLD ”. If the search co il is not in
mo tion an d not cl ose to metal, the detector sh ould b e silent. A light “ buzz”
adjust ment
is
r eco mmende d
to
insure

3. You can work in ma nual or in auto mat ic “ GR OUND BALANC E ” mo de s:
- In man ual gro und bala nce mode:
Search f or and se l ect a clear piece o f ground or san d t hat does not con ta in an y
met allic targ ets. Wit h the co il elev ated at least waist high and a wa y f rom an y
met allic targ et, slo wl y adjust the TH RESHO LD contr ol until a ver y f aint audio
threshold s ignal is heard.

Lower the se arch coil to with in one - inch of the gr ound surf ace while list ening
to the threshold audio signal. If the threshold sig nal is high tone , the
“GROUN D
BAL ANCE ”
contr ol
needs
to
be
decreased
(rotate
c ounter
clockwise). If the threshol d sig nal is low tone , the “ GROUN D BA LA NCE ”
control need s to b e increased (r otate clockwise). Keep repeating th is step until
threshold si gnal is the sa me wit hin one-inch of the gr ound as it is i n th e air.
Once this is acco mplished, the detect or is properl y ground balanced .
Wh en th e gro und mi neralizati on is r ejected, t h e det ect or can see d eeper t argets,
and is less suscepti ble to grou nd inter f erence.
Wh ile balanci ng t he detector, you h ave to be sure the re are no metal o bjects
around the se arch coil. If it seems di ff icult or imp ossib le to get little c ha nge in
the stead y thre sho ld as t he coi l is l owered, yo u ma y be atte mp ting to t one on

As a s earch c oil i s swept o ver the gro und, ign ore th e dis pla y and conce ntra te on
the sound the dete ctor makes. A s a search coil is p ass ed over a metal t h at is
likel y iro n tras h, t he sound will be l ow tone (245 Hz). Once f ami liar w it h the
sound t ypi cal iron produce, an oper ator ma y pa ss ov er such targe ts wi thout
consulting the disp la y indication, and continue se archin g, saving more time.
As a searc h coil is passed o ver a met al that is likel y go od, high tone s oun d will
be heard (7 00Hz). A good tar get t yp i call y produ ce a lo nger, more solid s ound,
no partial sig nals and mixed sig nals: high-low ton e. On ce a s mooth sol id signal
is heard, swee p th e search coil over the ta rget several ti mes and look a t the
displa y ind ication.
Wh en a metal targ et is detected , pro bable target t ype will be indicate d at
the top of the LCD screen. The Upper Scale, whe re the VDI curs or is

Of ten when detecting ver y ol d rust y iron objec ts and some iron wit h
impurities of nonferrous metal such as galvanize d ste el, or iron b ottle caps,
indication on the 1-st row ju mps f rom th e f irst to the last seg ment, an d vice
versa. This is alw a ys a signa l that is detected magneti c object. Such ite ms of
dubious an d mixe d signals more accu ratel y identif ied as iron, if yo u detect with
the edge of a searc h coil than if you a re just belo w the c enter of the coil.
Highl y mine ralize d soils have a grea ter impact on the d etector and thus t h e
accurac y of VDI . In high mineral iza tion detec ted si gn als can be cha nge d with
graphical and digi tal indicatio n, tha n when teste d in a ir or in low miner alized
or sand y s oil. U sua ll y such p laces V D I is shif ted to the l ef t. For exa mple, i f one
nor mal metal o bjec t is det ected with t he "sign " of the f o urth or f if th segme nt, if
buried in such mineralized groun d, indication ma y be the second or third
seg ment. S o whene ver in doubt of the displa y, che ck the detected obj ect, a nd so
over ti me you will learn to so me ext ent to recognize w hat has detected met al
detector!
Wh en a me tal targ et is detecte d , аlon g with the VDI cur sor of the f irst row ,
yo u can se e their co mmon VDI n u mb ers (0 -9 9), on the botto m row o n the
screen. “VDI =
“.
VDI (Visu al Dis cri mination Indic ation) is a di git al indication whi ch
depends on the me tal targets exact a llo y, size, and s ha pe. The ref erence label
below t he di spla y provide s a co mpa rison of kno wn t a rgets an d thei r co mmon
VDI nu mbers. Dif f erent meta l targe t s ma y share t he sa me VDI nu mbe rs based
8
on their electr ical characteristic s. V DI nu mbers f ro m 0 to 99 are ava ila ble and
cover the ent ire ra nge of allo ys and s izes.
Wh enever detectio n of met al obje ct s, initiall y conce n trate on t he sou n d
signal, so yo u can better deter mine th e exact locati on of the object.
3. “DI SC” knob is used to eli minate an y ta rget t hat yo u do not want t he
detector to a udibl y respond to .
If yo u need to el imi nate more f err ous metals over t he ground, the “ DISC”
control must b e se t in a position ov er “ Rings” or “C o ins”. If you co me upon
non-f errous me tals /gold, silver, copp er, bronze/ a high sound can be heard ; and
if you co me upo n f errous metal a low sound is heard. If the “DISC” control is
in low positi on - “ Iron”, e ver y f erro us object will be s ignalized wit h hig h tone
(like non – f errous ). If the soil i s too mineralize d we re co mmend the “ F oi l” or
“Iron” pos ition.
So me tras h metal s such a s pieces of lead , tin, cann ikin or p ot metal wil l
produce a g ood so und regardle ss of the DISC position.
4. IRON MASK m odе.

Note: If the poten tio meter " DISC" i s reduced t o a min imu m, the detector will
detect f errous ( magnetic) objec ts with high to nes, but will not di sp la y a n
indication of the t yp e of metal, as i t would be the f irst seg men t, and in this
mo de it is indicat ed b y a s ymbol f or IRON MASK . T heref ore it is preferable
when use mode IR ON MASK , poten t io meter " D ISC" t o be increased to at least

5. Searchi ng :
NRG-150 can wor k with 2 search coi ls - 27 cm. and 36 cm. Lar ge 36c m. s earch
coils are us ed to d etect large an d bul k y metal o bjects d eepl y burie d to ab out 1. 2
to 1.5 m maxi mu m, and a s mall pr obe is used to det ect and preci sel y locate
single coin depth o f abo ut 30-40cm. o r a large metal obj ects at depths up to 1 to
1.20 m (depe nding on s ize). Also, s mal ler co ils c an b e used in bushes, bu mp y
and uncomf ortable search locati on where it is i mpossible to use large coils.
The greater the s ize of the search coil, the greater will be the depth of
detection, b ut wit h the increa se of the coil size , will be hard to detect ver y
small metal obj ect s. The dif f erence in depth of detection using large c o ils is
appreciable f or lar ge metal obj ects s uch as a large met al object is, t he gr eater
the dif f erence in d epth of detection b etween lar ge and s mal l searc h coils ! I.e. if
the dif f erence in depth of detection o f large and s mall c oils f or me diu m co in is
3-4c m., the dif f erence in depth of detection as metal cup or pot of coins is
about 15 c m. Ther ef ore, the use of large coils makes s ense if you look b ulk y
ite ms and it is i mp ortant to f ind the best possible dept h. Disadvantage of larger
sensors is their si ze, require a f lat and clean places t o look. In conta minated
areas with l ots of scrap metal i s advis able to use s maller probes.
To test f or stud yi ng the characterist ics of the device, you can make po l yg on
where buried vari ous metal ob jects at dif f erent depths. Also you can put to the
10
ground si zes me ta l objects. Move t he search coil a t diff erent heights above
the m and yo u wil l learn to e valuat e the size an d de pth of the metal object
depending on th e intensit y and d ura tion of the so und. Af ter a while yo u will
learn to recogn ize objects that lie just bel ow th e su rf ace or at de pth. For
exa mple, the sign al f rom a small o bject located near the surf ace of th e earth
will disappear or d ecrease signif icant l y if you raise the coil, while if the object
is large, even the deep signal it will hardl y cha nge if yo u rai se the coil. Also,
note the dur ation and f requenc y of the sound mode when plug ged Pin Point
(VCO).
6. Pinpoi nting a T arget
A good method f or pin pointin g is "X -ing" the targe t with the search coil.
Re me mber that the target's respons e s ound is al wa ys gre atest when t he targ et is
directl y un der the center of the searc h coil.
To "X" a tar ge t, squeeze a nd hol d the trigge r
located on the h an dle and s weep t he search coil over th e target f ro m si de t o side
and then f rom f ront to ba ck u ntil yo u can ident if y th e ce nter of the X — t he spot
on the ground whe re the t arget r espo nse sou nd is the gr eatest. U se lou dest tone,
displa y lev el indic ation – bars on the 1 s t ro w, to ind icat e targets exac t cen ter.
Pinpointi ng a targ et is proba bl y best done b y "X -ing" as well. Re me mbe r that
the detector will b eep just as the tar get passes unde r the center of the search
coil. Sl owing the s weep spe ed do wn will hel p you pick out t he cen ter of t he X,
but reme mber that the search coil mu st alwa ys be moving slightl y f or target
detection.
11
Another ea s y met h od is to sweep t he coil f rom side t o side across the tar get in
ver y sho rt s weeps as you slowl y mo v e f orward and bac kward acr os s the t arget.
Slow do wn th e sw eep rate a nd s hort en the s weeps unt il you just b arel y get a
response at o ne spot. The target will be directl y be low the coil center at this
response time – f ig.4 Then turn 90 degrees an d swe ep the coil side t o sid e
noting the ce nter f ro m this new direc tion. "X" marks th e spot that yo u ne ed to
dig. Where the tw o loudest beep in t ersect, is t he cent er of the target. R elease
the toggle s witch t o the center positi on bef ore continue to search
You can practice with a coin on top of th e ground to beco me acquaint ed
with this t echnique .

7. The det ection depth depe nds o n t he follow ing :
-size, shape and l ocation of the object in the soil. The bigger the ref lecting
surf ace of the object the deeper it is t o be f ound;
-soil co mpositio n and minera lization level – the drie r and more ho mog e neous
the soil the easier it will be to ada pt the devic e and f or the device to detect
deeper. Under ston es, dr y sand or in cla y ute nsil, metal s are easier to be found
than in f reshl y dug out or da mp soil.
-the longer the ob j ect has bee n in t he soil the easier it will be to be f oun d as a
result of the good contact with the soil.
-t yp e of detecting coil. The bigger th e dia meter of the coil the deeper it w ill be
able to detec t meta ls.
-operator 's experi e nce and skil ls.
12
You can do f ield t ests b y yo urself us ing the device if you bur y dif f erent met al
objects in dif f erent depth but yo u sh ould leave th e m in the ground for at least
3 mo nths . T hus th e test results wil l be more reliable. You should mind t he soil
t yp e and the moist ure co mposi tion in it. Best result s ar e received whe n th e soil
is dr y.
Freshl y-bu ried ta r gets will not prod uce the nor mal de pth and discri min ation
results of targets t hat have been na turall y lost and s ettled in the ground. I t ma y
take a nu mber of ye ar s f or f reshl y- b uried targets to re spond at true dept hs and
discri minat e accur atel y.
The best wa y to de ter mine true detect ion depth is to use real search co nditions.
To reduc e f alse si gnals w hen s earch ing in a ve r y tra s h y grou nd, s can o nl y a
small area at a ti me using slo w, shor t overlappin g sweep s.
Keep the searc h c oil moving a t a c omf ortable ra te. If you walk too f as t, yo u
can’t overlap your s sweeps and yo u will mi ss a lot of ground. Also if you sweep
too f ast, yo u will l ose sensiti vit y and mi ss the d eep targ ets
8. Using a head phone
You sho uld al wa ys use a h eadpho ne whenever yo u sea r ch with yo ur metal
detector. Head pho ne is especiall y us ef ul in nois y are a, such us the beac h and
rear cit y area. It enhances audi o pe rception b y bri ngi ng the sound d ir e ctl y t o
yo u r to your ears while maski ng “ outside” noise int erf erences. You s hell be
ama zed at ho w mu ch be tter yo u can hear t he d etector si gnals w ith the
headphone than yo u can with the speaker alone. Using head phones also save
batter y pow er .
To conne ct a head phone to the detect or, insert the 3,5 mm. headp hone jack
into the “ Phones ” on the f ront panel , or 6,3 mm. head ph one jack i nto the s ocket
on the bott o m of th e box .
NOTE: Th e detec tor internal sp eak er will be disc on nected when yo u
connect a hea dphone.
9. Chargi ng stor a ge batteries and i ndications for the ir status.
13
If a light “ Low battery ” appears whi le using th e detect or that mea ns you
have to stop using it and recharge the batteries as f ollows: put the jack of the
charge device i nto “CHARG E” nest and place the de vice into electr ic net of
220V.
The chargin g is a uto matic an d begi ns when th e devi ce is SWI TCHE D
OFF and yo u plug the charger in to t he charging j ack o f the back panel o f the
device. The jack c age is “-” an d the mi ddle ter minal is “ +”.
Charging dep endin g on the level of discharge of the batteries. It’s not nece ssar y
to keep e ye s on charge device, beca use it is supplied with auto matic tur n off
and batteries coul dn’t be da maged no ma tter how lo ng the y will sta y in the
charge device. The chargi ng continue s till the mo men t when the batteries reach
their maxi mu m ca pacit y When rea ch ing their f ull capa cit y t he red ligh t on the
charger will not light an y mo re.
Wh en the y are rea d y pull the device out of the e lectric net and unplu g the jack
out of the “CHAR GE”
NOTE: Don’t unplug the c harger i f charge pr ocess i s n ot fini shed.
Alw ay s charge device's storage bat teries ONLY w ith the paired char g ers to
it. Thus y ou w ill prevent da mages or confusio n betw een “+” and “ -” b ecause
the use of other c hargers or a dapto rs may lead to irretrievable da mag es in
the batterie s!
10. Possi ble p ro bl ems duri ng ex ploi tation of NRG 1 5 0 :
1. When sw itching it on you ca n not h ear a sound, no an y i ndicatio n on the
LCD that t he devic e is switche d on. It mi ght ind icate f or:
-storage batterie s are dead (usuall y af ter a long period of time). Charg e the
