ABOUT YOUR DETECTOR  
The 1266-X wa s designed to exc el in three wa ys: depth,  
disc rimina tion a nd simplic ity. It offers a better c ombina tion of  
these three c ha ra c teristic s tha n a ny other meta l detec tor  
we’ve ever built. And we’ve been building meta l detec tors  
sinc e 1931.  
Depth. Engineered to go deep in minera lized soil a t high levels  
of disc rimina tion. If youre a n experienc ed detec tor opera tor,  
you’ll find yourself rec overing good ta rgets a t depths you  
never rea c hed before. And you’ll rea lly a pprec ia te the loud,  
c lea r a udio response you get from those deep ta rgets.  
Discrimination. Detec t a ll meta ls or ignore tra sh a s you detec t  
va lua ble ta rgets. Twin disc rimina tion modes a llow you to  
switc h insta ntly ba c k a nd forth between a ny two levels of  
disc rimina tion. If youve found ta rget ID meters c onfusing or  
ina c c ura te, you’ll like this quic k a nd simple wa y to help tell the

Simplicity. This is the kind of unc omplic a ted detec tor you  
would expec t from the c ompa ny tha t pioneered a utoma tic

CONDENSED OPERATING INSTRUCTIONS  
The 1266-X is ba sic a lly a turn-on-a nd-go meta l detec tor. It  
doesnt ta ke a n engineer to opera te it but you’ll ha ve more  
fun a nd a better c ha nc e of ma king tha t BIG find if you ha ve a  
c omplete understa nding of wha t you’re doing. Tha ts why we  
strongly rec ommend tha t you rea d the entire ma nua l. But if  
you just c a nt wa it a ny longer a nd you’ve a lrea dy used a  
Fisher “X” detec tor, here’s some quic k instruc tions to get you  
going.  
1. Set the c ontrols a s follows:  
DISC 1 = 4 (sma ll na il disc rimina tion)  
DISC 2 = 7 (Pull ta b disc rimina tion)  
SENSITIVITY = Pull a nd turn 3/4 c loc kwise  
OFF/VOL = Full c loc kwise1  
2. As soon a s you turn the detec tor on, it is  
a utoma tic a lly tuned a nd ground a djusted in the  
DISC 1 sea rc h mode.  
3. DISC 1 a nd DISC 2 a re motion modes. The  
sea rc h c oil must be a t lea st slightly in motion to  
detec t a ta rget.  
4. When you loc a te a ta rget, push a nd hold the  
TRIG G ER SWITC H for further ta rget identific a tion in  
DISC 2. If your ta rget still sounds good, dig it.  
5. With pra c tic e, you should be a ble to pinpoint in  
either of the DISC modes by moving the c oil  
slowly ba c kwa rds a nd forwa rds a nd left to right  
a nd fina lly stopping over the a rea of the  
strongest ta rget response. The ta rget should be  
a pproxima tely c entered benea th the sea rc h c oil.  
6. To use the Zero-Motion Pinpointing mode,  
simply pla c e the c oil on the ground (a wa y from  
the ta rget), pull a nd hold the trigger, lift the c oil  
a bout a ha lf inc h a nd bring it ba c k over the  
ta rget a rea a s you would in a DISC mode. The  
differenc es being tha t you don’t ha ve to keep  
the c oil in motion to get a response.  
7. HAPPY HUNTING !  
1. If you’re using headphones, reduc e the volume of the headphones  
to a c omfortable level when passing the searc h c oil over a large,  
shallow target.

SETTING UP  
Your 1266-X is just a bout rea dy to use. The only a djustment  
required is the a ngle of the sea rc h c oil a nd the length of the  
stem. Ta ke a look a t Figure 1 a nd fa milia rize yourself with the  
pa rts of the 1266-X before proc eeding.  
1. Unpa c k it c a refully. You ma y wa nt to sa ve the  
c a rton a nd inserts for future stora ge or shipment.  
2. Depress the spring loc k on the lower stem a nd  
slip the lower stem into the upper stem. C onnec t  
the sea rc h c oil c a ble to the c ontrol housing.  
3. The stem length is a djusted by loosening the  
loc k nut a nd a llowing the spring loc k to sna p into  
one of the holes in the upper stem.  
4. The sea rc h c oil a ngle is a djusted by loosening  
the nylon wing nut on top of the sea rc h c oil.  
5. Adjust the stem length a nd the c oil a ngle so  
the sea rc h c oil rests fla t on the ground a bout 6  
inc hes in front of, a nd slightly to the right of your  
right foot (to the left of your left foot for left  
ha nders). Your a rm should be stra ight a nd  
rela xed, the grip held loosely.

SETTING UP  
REMEMBER • THE LONG ER THE SHAFT, THE MORE  
YOU WILL HAVE TO BEND YOUR ELBOW AND THE  
SOONER YOUR ARM WILL G ET TIRED. THE 1266-X IS  
BALANC ED FOR C OMFORTABLE SEARC HING IN A  
TIG HT SEMIC IRC LE AROUND THE FRONT OF THE  
OPERATOR.  
6. With the stem length properly a djusted, tighten  
the loc k nut a nd sea rc h c oil wing nut. C AUTION:  
Never use a pliers or a nything other tha n your  
ha nd to tighten the loc k nut or wing nut.  
7. Disc onnec t the sea rc h c oil c a ble from the  
c ontrol housing a nd wra p it a round the stem. A  
loose c a ble nea r the sea rc h c oil ma y c a use fa lse  
signa ls, but don’t wra p it so tight tha t it pulls  
a ga inst the housing or the c oil. Rec onnec t the  
loop c a ble to the housing.  
8. With the sha ft length a nd c oil a ngle properly  
a djusted, you should be a ble to move into your  
sea rc h” position by lea ning forwa rd very slightly  
ra ising your a rm (still stra ight) until the sea rc h c oil  
is a bout 1 inc h a bove the ground a nd 12 inc hes  
in front of your foot. The sea rc h c oil should be  
pa ra llel to the ground a nd ma y ha ve to be  
slightly rea djusted a t this point.  
9. If the a rmrest is too wide or  
too na rrow, you ma y bend it  
slightly inwa rd or outwa rd to  
meet your exa c t requirements.

CONTROL HOUSING  
1. DISC 1: DISC RIMINATE 1 is the sea rc h mode.  
The 1266-X a utoma tic a lly opera tes in DISC 1  
unless the TRIG G ER-SWITC H is pushed a nd held or  
pulled a nd held. DISC 1 is a full ra nge  
disc rimina tion mode. All types of meta l a re  
detec ted a t the zero level a nd most sma ll piec es  
of tra sh a re rejec ted a t the ma ximum level of ten.  
2. DISC 2: DISC RIMINATE 2 is simila r to DISC 1  
exc ept tha t it opera tes only when the TRIG G ER  
SWITC H is pushed a nd held. DISC 2 is used for  
ta rget identific a tion a nd/or pinpointing.  
3. STEREO HEADPHONE JACK: Ac c epts most  
stereo a nd mono hea dphones with one-qua rter  
inc h dia meter plugs. When used, the spea ker is  
a utoma tic a lly disc onnec ted. A hea dphone c a n  
be very helpful when hunting in noisy a rea s or  
detec ting fa int signa ls.  
4. SENSITIVITY: This is a dua l ra nge, push-pull knob  
tha t c ontrols sensitivity to ta rgets a nd soil  
minera ls. Pull a nd rota te c loc kwise for norma l  
opera tion in minera lized soil. Push a nd rota te  
c loc kwise for even more sensitivity in  
non-minera lized, non-c onduc tive soil. It should  
be noted tha t fa int erra tic c irc uit noise is a udible  
a t the full c loc kwise position.

from the c ontrol housing.  
DISCRIMINATION POINTS  
By a djusting DISC 1 a nd DISC 2 you will be a ble to ignore (or  
rejec t) sma ll piec es of meta llic tra sh a nd ground minera ls  
while detec ting va lua ble ta rgets. The lowest setting a t whic h  
a n objec t is rejec ted is referred to a s the objec ts  
“disc rimina tion point”. Disc rimina tion points a re determined by

DISCRIMINATION POINTS  
2. Pull the SENSITIVITY c ontrol out a nd turn full  
c loc kwise. (Ba c k it off slightly if c irc uit noise is too  
loud or a nnoying in the full c loc kwise position.)  
3. Turn the OFF/VOL c ontrol full c loc kwise. (If  
you’re wea ring hea dphones reduc e the volume  
to a c omforta ble level when the sea rc h c oil is  
over a la rge ta rget).  
4. Set DISC 1 a nd DISC 2 a t zero.  
5. Hold the sea rc h c oil a bout 2 inc hes a bove a nd  
pa ra llel to the ground. Move it slowly over the  
sa mples a nd note the sha rp loud response a s you  
pa ss over ea c h one. Keep in mind tha t DISC 1 a nd  
DISC 2 a re motion modes a nd respond only when  
the sea rc h c oil (or the ta rget) is moving.  
6. Inc rea se DISC 1 to a setting of 3 a nd a ga in pa ss  
over the ta rgets. Repea t this proc ess a t settings of  
4,5,6 a nd so on to 10. You will note tha t a s you

7. Push a nd hold the TRIG G ER-SWITC H. The 1266-X is  
now opera ting in the DISC 2 mode.  
8. Repea t steps 5 a nd 6 a nd you will note tha t the  
DISC 2 disc rimina tion points a re a bout the sa me a s  
DISC 1 disc rimina tion points.  
9. The a c tua l disc rimina tion points for different  
ta rgets ma y va ry slightly from DISC 1 to DISC 2 a nd  
from detec tor to detec tor. However,  
disc rimina tion points a re determined ma inly by  
suc h fa c tors a s ta rget size, sha pe, depth, type of  
meta l a nd ground minera liza tion.  
10. Some objec ts suc h a s sha llow bottle c a ps, bent  
pull ta bs or tra sh less tha n 2 inc hes from the c oil  
ma y be diffic ult to rejec t. The 1266-X will instea d  
respond with a strong broken signa l, whic h will,  
usua lly disa ppea r if the sea rc h c oil is ra ised slightly.  
(The strong signa l of a good ta rget will just get  
wea ker when the c oil is ra ised).  
11. The 1266-X will rema in silent when some objec ts  
a re rejec ted however other objec ts ma y “sna p,  
c ra c kle a nd pop” a s they a re rejec ted. This is a  
perfec tly norma l response indic a ting tha t the  
powerful disc rimina tion c irc uitry is doing its job.  
12. La rge piec es of tra sh suc h a s beer c a ns or ja r

Motion Mode.  
Ta ke a look a t the illustra tion a bove a nd note how the  
disc rimina tion level (a s well a s sweep speed a nd ground  
minera liza tion) a ffec ts the sea rc h c oil detec tion pa ttern. Not  
only is depth reduc ed a t high disc rimina tion levels but a lso the  
width of the pa ttern is reduc ed. This c ha nge in width ha s a  
very importa nt implic a tion: if youre sea rc hing a t a high level  
of disc rimina tion youll ha ve to sweep a lmost direc tly over a  
ta rget to get a response. The higher the degree of ground  
minera liza tion, the more pronounc ed this effec t.  
This is where the 1266-X dua l disc rimina tion system c omes in.  
Set DISC 1 a t a low level (like 2 or 3) a nd DISC 2 a t a higher  
level (6 or 7). As you sea rc h in DISC 1 youll ha ve a better  
c ha nc e of finding good ta rgets. Of c ourse, you’ll get more  
tra sh too, so when you do get a response, switc h over to DISC  
2. If you still get a good response, dig it, keeping in mind tha t  
ha d you been sea rc hing a t a high level of disc rimina tion you  
ma y well ha ve missed this one. This is the preferred method of  
sea rc hing in rela tively non-tra shy soil.  
In very tra shy soil however it is genera lly ea sier to sea rc h  
with DISC 1 a t a high level of disc rimina tion (a t the pull-ta b  
disc rimina tion point for exa mple) a nd DISC 2 a t a lower level  
of disc rimina tion (3 for exa mple). In this ma nner a good ta rget

6. Sea rc h in a methodic a l ma nner. Pa y c lose  
a ttention to where you’re going a nd where  
you’ve been.  
7. Keep the sea rc h c oil moving a t a c omforta ble

detec tor a nd responds only when the sea rc h c oil  
(or the ta rget) is moving while in the DISC modes.  
8. TAKE YOUR TIME. Also very importa nt. If you  
wa lk too fa st you c a nt overla p your sweeps a nd  
you’ll miss a lot of ground. If you sweep too fa st,  
you’ll lose sensitivity a nd miss the deepest ta rgets.

PINPOINTING  
ZERO MOTION PINPOINTING MODE  
Ta rget loc a tion is a sna p using the Zero-Motion Pinpointing  
mode. You do not ha ve to keep the c oil moving to get a  
response in this mode.  
1. Onc e the presenc e of a buried ta rget is  
indic a ted by the beep-beep” of the 1266-X,  
simply pla c e the c oil LIG HTLY on the ground,  
a wa y from the ta rget a rea . Pull the TRIG G ER-  
SWITC H a nd hold. (At ma ximum sensitivity you  
ma y hea r a fa int tone, whic h will disa ppea r a s  
soon a s the c oil is ra ised. If the tone doesnt  
disa ppea r, lower the sensitivity slightly.)  
2. Ra ise the c oil 1/2 ha lf inc h or so a nd move it  
side to side a c ross the ta rget a rea a few times.  
3. Stop the sea rc h c oil over the c enter of the  
response a rea .  
4. Now move the c oil slowly forwa rd a nd ba c k a  
c ouple of times, a ga in stopping in the c enter of  
the response a rea .  
5. Repea t one more time, moving the c oil side to  
side. Your ta rget should be direc tly below the  
open c enter of the sea rc h c oil.  
6. For quic k a nd a c c ura te pinpointing of strong  
signa ls, pla c e the c oil on the ground very c lose  
to the a pproxima te ta rget a rea a nd pull a nd hold  
the trigger switc h. You ha ve now “tuned-out”  
most of the ta rget so you will only rec eive a  
response direc tly over or very nea rly over the  
ta rget.  
PINPOINTING IN THE MOTION DISK MODES  
Pinpointing in either DISC 1 or DISC 2 will ta ke a little pra c tic e  
but you ma y find tha t for most ta rgets, its even quic ker tha n  
the Zero-Motion Pinpointing mode. Simply use the sa me  
proc edure a s in steps 2 through 5 a bove. The only differenc e  
will be tha t when you stop the c oil over the ta rget, you will

PINPOINTING  
lose the a udio signa l. You MUST keep the c oil moving a t lea st  
slightly to determine the loc a tion of the strongest signa l before  
you stop it.

TARGET RECOVERY  
Onc e you ha ve pinpointed a ta rget, your objec tive is to

exc a va tion. There a re a lmost a s ma ny wa ys to do this, a s there  
a re Trea sure Hunters. Wha tever works for you is good enough  
a s long a s you don’t brea k a ny la ws, da ma ge vegeta tion, or  
lea ve your sea rc h a rea looking like a World Wa r II ba ttlefield.  
G enera lly spea king, bea c hc ombers do little if a ny da ma ge  
to the environment while rec overing ta rgets. However, if you

rec overy method c a n be very importa nt. Two of the most  
suc c essful methods a re illustra ted in a sepa ra te booklet  
enc losed with your 1266-X.  
WHIC HEVER TOOL OR METHOD YOU C HOOSE, REMEMBER THAT  
RESPONSIBLE TREASURE HUNTERS TAKE PRIDE IN THEIR ABILITY TO  
LEAVE SOIL AND VEG ETATION INTAC T AND UNDAMAG ED.

RECOVERY TOOLS  
1. A hea vy duty, blunt sc rewdriver is c ommonly  
used by expert Trea sure Hunters a nd the tool of  
c hoic e for c ut la wns.  
2. A sturdy hunting knife with a 5-inc h bla de will  
do the job in most other soils. A high qua lity  
double-edged “surviva l” knife is even better  
(a nd more expensive) c hoic e sinc e it will be  
a lmost impossible to bend or brea k.  
CAUTION: Using a jac k knife without a loc king  
blade is a good way to lose a finger!  
3. A na rrow ga rden trowel will work in loose or  
wet soil.  
4. Severa l exc ellent digging tools a re ma de just  
for the Trea sure Hunter a nd espec ia lly designed  
sa nd sc oops a re a va ila ble for bea c hc ombing.  
5. A thin, dull probe is the preferred tool for  
prec ise ta rget loc a tion.  
OPERATING TIPS  
1. We’ve a lrea dy sa id it but it bea rs repea ting:  
TAKE YOUR TIME AND OVERLAP YOUR SWEEPS.  
2. Keep your disc rimina tion levels set low. You’ll  
dig more tra sh but you’ll find more good ta rgets,  
too. If you c ontinua lly run a t the pull-ta b  
disc rimina tion level you’ll find c oins a nd silver  
rings but very few gold rings for exa mple.  
3. Use a good hea dphone. You won’t miss fa int  
ta rgets, you won’t a ttra c t unwa nted a ttention  
a nd you won’t bother others.  
4. Pra c tic e pinpointing. There’s nothing sa c red  
a bout the methods desc ribed in this ma nua l.  
Ma ny 1266-X users ha ve developed their own  
pinpointing methods.  
5. Alwa ys bury a c oin when working in unfa milia r  
territory a nd c hec k it a t different disc rimina tion  
a nd sensitivity levels. There is some sensitivity loss  
a t higher levels of disc rimina tion. The grea ter the  
14  
 
OPERATING TIPS  
ground minera liza tion, the higher the sensitivity  
loss. For exa mple, you ma y be a ble to detec t a  
penny 6 inc hes deep a t zero disc rimina tion, but  
no deeper tha n 4 inc hes a t the pull ta b  
disc rimina tion point. Also, ground minera liza tion  
c a n reduc e a detec tors a bility to disc rimina te  
a c c ura tely. In highly minera lized soil, some tra sh  
ta rgets ma y not be rejec ted.  
6. If a ta rget gives a good strong response in the  
sea rc h mode but no response in the Zero-Motion  
Pinpoint mode, you ma y ha ve “tuned-out” your  
ta rget (a nd a ll others) by pulling the TRIG G ER-  
SWITC H over a nother piec e of meta l. If you  
suspec t this ma y be the c a se, c hec k the ground  
first in DISC 1 a t zero disc rimina tion to insure  
there’s no buried meta l before pla c ing your c oil  
on the ground a nd pulling the TRIG G ER-SWITC H to  
go into the pinpoint mode.  
7. In tra shy a rea s, to reduc e the “ma sking”  
effec ts of tra sh on nea rby good ta rgets, use a  
shorter a nd slower sweep pa ttern. Also, the  
optiona l sma ller 5-inc h sea rc h c oils will zero in on  
good ta rgets c loser to tra sh.  
8. When in doubt a bout the possible identity of a  
ta rget, dig it up.  
9. The 1266-X is a n ea sy detec tor to use but if  
you’re ha ving trouble with a ny a spec t of its  
opera tion (pinpointing, sea rc hing, fa lse signa ls,  
etc .) go ba c k a nd rerea d the pa rt of this ma nua l  
rela ting to your problem.  
15  
 
FALSE SIGNALS  
Due to the extreme sensitivity of the 1266-X, youre bound to  
get some “fa lse signa ls” onc e in a while. A fa lse signa l oc c urs  
when something tha t shouldnt sounds like a good ta rget. The  
1266-X does a good job of rejec ting junk but it is so sensitive  
tha t hot” minera lized spots in the soil, la rge, c a n fool it piec es  
of junk, some kinds of bottle c a ps a nd pull ta bs or tra sh less  
tha n 2 inc hes from the c oil.  
So wha t do you do a bout fa lse signa ls? Well, 90 perc ent of  
them will sound suspic ious to you a fter you’ve ha d some  
experienc e a nd you’ll just ignore them.  
They ma y be very fa int or very a brupt with sta tic . Often  
when you go ba c k over the sa me spot, a fa lse signa l will  
simply disa ppea r. Other fa lse signa ls ma y be very loud a nd  
sha rp but most of these will a lso disa ppea r if the c oil is  
speeded up or ra ised slightly. Some sha llow, la rge or irregula r  
piec es of junk however, will sound off no ma tter wha t you do.  
You ma y reduc e the number of fa lse signa ls by inc rea sing the  
disc rimina tion level a nd/or reduc ing the sensitivity. Some other  
sourc es of fa lse signa ls a re:  
1. ELECTRICAL INTERFERENCE: C aused by radio/TV  
stations, power lines, nearby detec tors operating at  
the same frequency. SOLUTIONS: Move further away,  
lower the sensitivity, and reduc e sweep speed.  
2. HIGHLY MINERALIZED SOIL: Usually c auses  
c onstant static or good target sounds. SOLUTIONS:  
Make sure youre in the normal “Pull” sensitivity  
c ontrol position. Lower the sensitivity, inc rea se the  
disc rimination, raise the searc h c oil until false  
signals disappear and sweep at that height.  
3. WET SAND: Sa me a s highly minera lized soil.  
4. ELONGATED FERROUS OBJECTS: If you hea r two  
beeps very c lose together a nd c a n’t find either  
one, you’re proba bly over a na il or some other  
long iron objec t. But a very sha llow c oin or a  
buried c oin on edge ma y give the sa me  
response. In a ll c a ses, the ta rget will be between  
16  
 
FALSE SIGNALS  
the beeps or, if you sweep a t right a ngles to your  
origina l direc tion, you’ll rec eive a single beep  
direc tly over the ta rget (exc ept for the very  
sha llow c oin). One wa y to tell the differenc e  
between a c oin a nd a na il is to set your  
disc rimina tion a t a bout 5. Most sma ll na ils will be  
tuned out while most c oins will respond with a  
good, smooth signa l.  
5. EXTREMELY TRASHY SOIL: May result in a  
c onstant c hatter or “snap, c rac kle and pop” with  
assorted, hard to find good signals. The obvious  
solution is to inc rease the disc rimination level to  
maximum. Slow down your sweep speed and  
shorten your sweep pattern. An even better  
solution is to try one of the optional 3-3/4" or 5" c oils.  
You’ll be a ble to zero in on good ta rgets in the  
midst of junk.  
6. DIGGING TOOL: If you’re c a rrying a meta l sa nd  
sc oop, digging knife, sc rewdriver or wha tever,  
hold it behind your ba c k or keep it a bove your  
wa ist. Your 1266-X is sensitive enough to sound off  
ea c h time you sweep the c oil benea th it.  
Fa lse signa ls ma y a lso oc c ur in the Zero-Motion Pinpointing  
mode. When in this mode, the 1266-X detec ts a ll meta ls so you  
ma y pinpoint a piec e of nea rby junk instea d of your good  
ta rget. The solution is simple: a lwa ys rec hec k your ta rget a rea  
a fter rec overing a ny ta rget to insure tha t you ha ven’t missed  
something. Or lea rn to pinpoint in the disc rimina tion modes.  
You ma y a lso rec eive fa lse pinpointing signa ls in highly  
minera lized soil. In this c a se, it is importa nt to keep the c oil  
pa ra llel to the ground a nd a t lea st a n inc h a bove it.

MAINTENANCE  
Your 1266-X doesnt require a lot of c a re but there a re a few  
things you should do to keep it in pea k opera ting c ondition.  
1. If you’re not going to be using it for a while,  
ta ke the ba tteries out. Ac id da ma ge c a used by  
lea king ba tteries c a n be severe.  
2. Avoid extreme tempera tures like the inside of a  
c losed c a r sitting in the sun. Even worse, inside  
the trunk of a c a r.  
3. If you “sc rubthe sea rc h c oil on the ground,  
you’ll eventua lly wea r through the bottom.  
Repla c ement c oils a re expensive. Instea d, invest  
in a n in expensive c oil c over.  
4. Put a pla stic ba g over the c ontrol housing if  
you’re hunting in ra in, fog or dust.  
5. Keep your 1266-X dry a nd c lea n. Wipe off the  
lower stem before sliding into the upper stem a nd  
keep the loc k nut free of sa nd a nd dirt.
