GENERALDESCRIPTION
TheGoldenSabreIIishighperformanceVLFmetaldetectorthatiscapableofrejectinggroundmineralizationandburied
metallictrashsimultaneously.ItincludesNotchDiscriminationsothatmostcommonpulltabscanberejectedwithoutlosing
nickelsandsmallgoldrings,orsothatonlyaparticularbandofdesiredtargetswillbedetected.NotchToneTargetID
providesalonetonefortargetsbelowtheNotchLevelsetting,andahighertonefortargetsabovetheNotchLevelsetting.
Designemphasiswasplacedonperformanceandeaseofuse,whileminimizingoreliminatingthosetroublesome
adjustmentsandfeaturesthatcouldcausealossofperformanceifnotusedproperly.
TheSilentSearchdiscriminatemodeisbasedonmotion,whichmeansthatthesearchcoilmustbemovingslightlyto
detectatarget.Themotionrequiredissoslightthatpinpointingispossibleinthismode,howeveranomotionpinpointmode
isincluded,whichwiththe8inchopencentersearchcoilmakespinpointingaverysimpletask.Theautomaticground
rejectioncircuitryissettoallowoperationinvirtuallyanymineralizationyoumightencounter,althoughoperationmaybe
difficultinblacksand.TheGoldenSabreIIutilizesTesoro'sadvancedHighGainSensitivitycircuitrywhichwillprovidegreater
depthinparticularenvironmentsplusahigherdegreeofsensitivitytosmallerlessconductivetargetssuchasgoldjewelry.An
expandeddiscriminatorisaddedforgreaterselectivityofhardtoidentifytargetspreviouslydetectableonlywhenhuntinginAll
Metalmode.TheGoldenSabreIIiseasilyconvertedtohipmountoperationwithouttheneedofkitortools.Additionaleight
footlengthofsoftbraidedshieldcableeliminatestheneedofanextensioncable.Tesoro'sexclusivemonolithicallyshielded
searchcoilcomplimentsthetechnicaladvancementsengineeredintoyournewGoldenSabreII.
Theunitisfurnishedwithan8"opencenterconcentricsearchcoil.Wefeelthatthiscoilwillprovideexcellentperformance
inmostsituations.Theopencentergreatlysimplifiespinpointing.
Aswithanydetector,thefamiliarityoftheuserwiththeinstrumentwillhaveagreatdealtodowithhowsuccessfulthe
treasurehunteris.Werecommendthatyoureadandunderstandthismanualfullybeforeattemptingtousetheinstrumentin
thefield.
Besuretofilloutandmailyourwarrantyregistrationcardtovalidateyourwarranty.
ASSEMBLY
TheGoldenSabreIIcanbeassembledineitheroftwoconfigurationsoreasilyconvertedfromonetotheother.The
electroniccontrolhousingcanbemountedonthearmrestpole,orcanbebodymounted.Installationofthelowerpoleand
coilisthesameforeitherconfiguration.
1. Depressthetwobuttonsontheupperendofthelowerstem,andslideitintotheupperstem.Pushthelowerstem
upsothatthebuttonsclickintothethirdsetofholesfromtheendoftheupperstem.
2. Insertthepoletipbetweenthemountingearsofthesearchcoil,afterremovingthescrewandthumbnut.Alignthe
holesinthepoletipandthoseinthemountingears.Besurethattherubberfrictionwashersareinplace.
Itwillbemucheasiertoinserttopoletipintothesearchcoilearsifyoumoistenthepoletipwashers.
3. Insertthecoilmountingscrewthroughthecoilandpoletip.Besuretheinternaltoothlockwasherisonthescrew
headside.
4. Installthethumbnutonthescrewandtightenbyhand.
5. Windthesearchcoilcablearoundthepole.
6. Leaveenoughslackinthecableatthesearchcoiltoallowadjustmentofthecoil'sangel.
CAUTION:Toomuchslackmaypermitthecabletoflapacrossthesearchcoilwhileinusecausingfalsesignals.
POLEMOUNT
1. Thecontrolhousingisalreadymountedonthepole,asshippedfromthefactory,soallthatisnecessaryistoinsert
thesearchcoilconnectorintothecontrolhousingconnector,andtightenfingertight.
2. Usethetwovelcrostrapstoholdthecabletightagainstthepole.
NOTE:Thecablewilllastmuchlongerinthebodymountconfigurationifsomecareistakentospreadthenecessary
flexingoveralargearea,ratherthanmakingasharpbendawayfromthepoleatcableclipwhichwouldconcentratethe
flexinginasmallarea.
BODYMOUNT
1. Tousethedetectorasabodymount,simplyremovethecontrolhousingfromtheupperpolebydepressingthe
springnutsintheplasticmountingpiece,andslidethecontrolhousingoffthepole.
2. Insertthesearchcoilconnectorintothecontrolhousingconnectorandthenfingertighten.
3. Usethetwovelcrostrapstoclampthesearchcoilcable.Itwillbebestforyoutosometimesmovethestrapssothat
thewearonthecableisspreadoveralargearea.
CONVERSION
Obviously,convertingtheunitfrombodytopolemountorviceversa,issimplyputtingthecontrolhousingbackonthe
pole,orremovingitfromthepole.Besuretokeepthesearchcoilcablewoundtightenougharoundthepolethatitdoesn'tflap
rightoversearchcoilhousing.TheGoldenSabreIIisstrongenoughtoseethetinycablewiresmoving,andcangiveyoufalse
signalsifthecableistooloose.
Thearmrestontherearofthehandlecanbemovedforwardbyremovingthescrewsandnuts,andreinstallingthe
assemblyintothemostforwardsetofholes.

CONTROLS
TheGoldenSabreIIhasfivecontrolsonitsfrontpanel,andathresholdadjustonitsrearpanel.Thefrontpanelcontrols
areallreadilyadjustedwiththeindexfingerofthehandholdingthedetector.
1. ON/OFF,BATTERYTEST,SENSITIVITYCONTROL.Theprimaryfunctionofthiscontrolistoreducethedetectors
sensitivitytothoseinfluencesthatcouldmaketheoperationmoredifficultforyou.Thiscontrolalsoisusedtoturnthe
poweronandoff.Turningtheknobcompletelycounterclockwiseuntilitclicksdisconnectsthebatteriesfromthecircuit.
Whentheknobisfirstturnedon(clockwise),thedetectorwillautomaticallytestitsbatteries,andgiveyouanaudible
indicationoftheirconnection.
NOTE:ThistestshouldbeperformedwiththeModeSwitchintheDiscriminateposition.Freshbatterieswill
causealoudaudioresponsewhichwillgraduallydecayintosilenceoveraperiodofabout4or5seconds.Asthe
batteriesageandbecomeweaker,theinitialaudioresponsewillbeweaker,andwilldecayquicker.Whentheresponse
isjustashortbuzzinsteadofalongbeep,orwhenthereisnoaudioresponse,it'stimefornewbatteries.Itis
recommendedtoalwaysusealkalinebatteries.
Manythingscancausetheresponseofthedetectortobecomeerraticasyouareusingit.Normallyyouwillnothearany
soundfromthedetectorunlessyoupassthecoiloveragoodtarget.Verylargetargetsoramultitudeofcloselyspaced
smallerrejectedtrashtargetscancausethedetectortoemitchoppysputteringsounds.CBradios,radioandTV
broadcastingantennas,intensemineralizationchanges,andothersourcesofelectricalnoisecanalsocausethedetector
toemitfalsesignals.Thesesignalswillgenerallysound"chopped"andwillnotberepeatablesoyouwillnothaveany
troublerecognizingthem.Theycanbedistracting,though,andturningdownthesensitivitycontrolwillhelpreducethem.
Thiswillalsocauseasmalllossoftargetsensitivity,soalwaysrunthesensitivitycontrolashighasyoucan,whilestill
gettingsmoothoperation.
2. SEARCHMODESWITCH.ThisswitchisusedtoselecttheAllMetalmodeofoperationortheDiscriminatemode.
TheDiscriminatemodeisaSilentSearchultraslowmotiontype,andallowsalotofusercontrolduetoitsextrafeatures
likenotchdiscrimination.TheAllMetalModeisanomotion,automatictuned,allmetalmodewhichutilizesaninternally
fixedthresholdsound.
3. DISCRIMINATELEVEL.Thiscontrolisusedtoadjustthedetector'sresponsetounwantedmetallictrashwhenused
intheDiscriminatemode.Atthelowestsetting"0",thedetectorwilleliminatemostironobjects,butwillstillrespondina
positivemannertolightfoil,bottlecaps,pulltabsandmostothermetallicitems.Astheknobsettingisincreased,
responsetomoreofthesemetallictrashitemsisreversedsothattheseobjectsgivenoresponse.Eachdetectorcan
varysomewhat,soitwouldbeagoodideatotestyourdetectoragainstvarioustargetstodetermineexactlywherethey
arerejectedbyyourdetector.DothiswiththenotchmodeswitchintheOFFposition.
4. NOTCHMODESWITCH.Thistoggleswitchisusedtoselectthefunctionofthenotchfilterinthediscriminator
circuitry.Intherejectmode,thetargetencompassedbythenotchwillberejected,andintheacceptmode,onlythose
targetsencompassedbythenotchwillbedetected.Thenotchwidthisfactorsettobejustwideenoughtoincludethe
commonpulltabsandlifttabs,sincerejectingtheseobjectswillbeitsprimaryuse.Inthecenterposition,thenotchfilter
isdisabled,sothatithasnoeffectonthedecimatedcircuit.
5. NOTCHLEVELCONTROL.Thiscontrolisusedtoadjustthenotchfilterresponsetothedesiredtargetlevelwhen
usingthenotchdiscriminatemodes.Thenotchlevelcontrolshouldalwaysbesethigherthanthediscriminatelevelbyat
leastonefullincrementforproperoperation.Thiscontrolalsocanserveasatonecontrolifthenotchfilterisnotused,
sincealltargetsbelowthenotchlevelareindicatedbyaloweraudiotonethanthoseabovethenotchsetting.Settingthe
controlat'0'willprovidethehigheraudiotoneforalltargetsdetectedintheDiscriminatemodewhilesettingitat
maximumwouldprovidetheloweraudiotone.
6. THESHOLDCONTROL.Thiscontrolisplacedonthebackpanelofthedetector,sinceitrequiresverylittleusage.
Oncethecontrolisadjustedtothedesiredthreshold,itwillnotrequirefrequentresetting.Turncontrolclockwiseor
counterclockwisetoasettingwherebythetoneisbarelyaudible.
TUNING
SincethemosttroublesomeadjustmentsofstandarddetectorshavebeenautomatedintheGoldenSabreII,thetuning
procedureforthisdetectorissimplyamatterofselectingthedesiredoperatingmode,settingthesensitivitylevel,andthe
discriminatelevel.Ifyouselectthediscriminatemode,youshouldbeginoperationwiththesensitivitycontrolsetatabout7.
Inmostsituationsyouarelikelytoencounter,youwillbebaletooperateatthissetting.Iftherearesourcesofelectrical
interferencepresent,oriftheareaisextremelytrashyormineralized,yourdetectormaygivesomefalsesignals.These
signalsaregenerallyshortchoppysoundswhichcaneasilybedistinguishedfromagoodtargetresponse.Turningdownthe
Sensitivitycontrolwillhelptoeliminatemostofthesesignals,ifnecessary.Itmayalsobepossibleinsomeareastoincrease
thesensitivitysetting.
SELECTINGTHEPROPERMODEOFOPERATION
TheGoldenSabreIIofferstwobasicoperatingmodes,PinpointAllmetalorDiscriminate.TheDiscriminatemodealso
hasthefurthercapabilityofusingnotchdiscrimination.
A. ALLMETALMODE.Thismodeisusefulforrelic,cache,ornuggethunting.Thegroundrejectionisinternallypreset
sothatnormalsoilmineralizationisslightlypositive.Thismeansthethresholdsoundwillincreasesomewhatasthe
searchcoilisloweredtotheground.Theautomatictuningshouldkeepthedetectortunedtothresholdasyouareusingit,
butbymomentarilypunchingthemodeswitchtothefasttuneposition,thedetectorcaninstantlybebroughtto
threshold.Allotherfeaturesofthedetector,suchasnotchtonetargetID#,andnotchfilter,arenotoperativewhenthe
unitisintheAllMetalMode.TheaudiosoundisalwaysthelowerofthetwonotchtoneswhenintheAllMetalMode.
B. DISCRIMINATEMODE.TheDiscriminateModeismotionbased,andrequiresthatthesearchcoilbemovingslightly
fortargetdetection.ThereisnothresholdsoundpresentasintheAllMetalMode.ThenotchtonetargetIDfeatures
worksintheDiscriminateModeevenifthenotchmodeswitchisintheoffposition.Thenotchlevelcontrolsetting
determineswhetheratargetindicationishighorlowtone.AllTargetswithphaseresponsebelowthenotchlevelsetting
willberepresentedbythelowertone'beep',thosehigherthanthenotchlevelsettingbyahighertone'beep'.
Werecommendsettingthesensitivitycontrolatthe(7)markwhenbeginningtosearchanewareainDiscriminateMode.
Ifthedetectorseemstohavealotof'chirpy'soundorfalsesignals,turnthesensitivitycontroldownslightlyuntilthesourceof
theinterferenceisovercomeandthedetectorwilloperatesmoothly.Notethatinverylargetrashareas,someclickingor
chirpysoundingfalsesignalswillbecausedbytheheavyconcentrationsofmetallictrashorbyverylargeironobjects.In
relativelycleanareas,itmaybepossibletoincreasethesensitivitysetting.
WhentheNotchmodeswitchisintheoffposition,theamountoftrashrejectioniscontrolledbytheDiscriminatelevel
Control.WiththeDisclevelcontrolsetatabout2or3,thedetectorshouldrejectfoilandferroustargets,whiledetecting
thosetargetwhosephaseresponseishigherthanfoil.Thisisshownbythesolidlinelabeledfoilreject.Asthecontrolis
increased,moreoftheremainingtargetsarerejected.Withthecontrolincreasedtoabout6or7,allofthetargetsshownare
rejectedexceptthepennyandquarter.Thisisshownbythedottedlinelabeledpulltabreject.Notethatatthislevel,the
nickelandsmallgoldringarealsorejectedasbadtargets.Sincesmallgolditemsmayhaveaphaseresponseaslowasfoil,
youcanseethatoperatinganormaldiscriminatoratthepulltabrejectlevelcanalsocauseyoutomissalotofvaluablefinds.
TheNotchFilterintheGoldenSabreIIcanhelpyoutoovercomethisinherentproblemofnormaldiscriminators.
NOTCHDISCRIMINATION.IntheNotchRejectMode,theresponseofthedetectorcanbemorecloselycontrolled.The
DiscriminatelevelControlisusedtosetthelowercutofflevel,forexample,toeliminateferroustargets,foil,andsteelbottle
caps.TheNotchFilteristhenusedtorejectthenarrowbandoftargetscontainingpulltabs.TheNotchwidthisfactorsetto
covertherangeofmostcommonpulltabsandliftringswouldfallinto,butsomepeculiartabsmaystillbedetected.Ifpull
tabshavebeenchoppedormutilatedbyalawnmower,thepiecesmaybedetectedasnickels,andofcourse,somevaluable
itemsmayhavethesamephaseresponseaspulltabsandberejected.Still,theNotchFilterallowsdetectionofnickelsand
smallgoldringswhilerejectingalmostallofthepulltabsignals.TheNotchlevelshouldalwaysbesethigherthantheDisc
level.
NOTE:ITispossibletoadjustthewidthoftheNotchFilter,butwerecommendforbestresulttoleaveitsetasitcomes
fromthefactory.IfitbecomesnecessarytoreadjusttheNotchWidthtosuitparticularcircumstances,contactyourdealerfor
details.
TheNotchAcceptModeallowsthedetectortorespondonlytoanarrowbandoftargets.Thismaybeusefulifyouare
searchingforaparticulartarget,suchasalostringortreasurehunttoken.Itisalsousefultohelpyouclassifyoridentifya
targetbeforedigging.
Eachdetectorcanvarysomewhatduetomanufacturingtolerance,soyoushouldexperimentwithyourdetectorand
becomefamiliarwiththerejectionlevelsforthesetrashitemswithyourdetector.
Earliermotiondetectorsthatoperatedwith"threshold"soundwouldgivetheuseradefiniteindicationofmetallictrashby
eithernullingcompletelyorbygeneratingshort,choppysounds.SincetheGoldenSabreIIoperateswithoutthresholdsound,
thereisnonullingtoindicatethattheareaisextremelytrashy,butundersuchcircumstancesthedetectorwillprobablyalso
emitsomeshortchirpysounds.Theseareeasytodistinguishfromthegoodtarget'slongercleanersound.
Sincethenotchfilterresponseislikea"window"thenotchlevelmustbecenteredonthedesiredtargets,ratherthanjust
sethigherthanthetarget.Thepresetmarkatthe'6'onthenotchlevelisanidealstartingpointtoprovidepulltabrejection
whilestillfindingnickels.Itwillprobablybenecessarytomakesomesmallcorrectionupordowntoaccuratelycenterthe
notchresponseonthepulltabrange.
Whensetcorrectly,thenotchlevelissettobejustwideenoughtoeliminatemostcommontabs.Thealuminumscrew
capissoclosetotheresponseofcoins,thatwefeelit'sbesttonotincludeitinthenotch.Thetargetsintheshadedarea
wouldberejectedbyaproperlyadjustednotchlevelinthenotchrejectmode.
Ifthenotchlevelweresettoohigh,thenotch'window'wouldnotincludethecompleteunbentolderstylepulltabsand
maystarttoeliminatepennies.
Ifthenotchlevelweresettolow,the'window'mayeliminatethenickel,andthenewerstyleofliftringtabswouldbe
detected.
Beginningoperationinthenotchrejectmodewiththenotchlevelcontrolsetatthe6or7markshouldputthenotch
windowreasonablyclosetothedesiredresponse.Ifyoubegintofindthecompleteolderstylepulltab,youshouldturnthe
notchleveldownslightly,andcontinuesearching.Ifyouarefindingthenewerstyleliftringswhichhavebeentornoffthecans,
it'sasignaltoraiseyournotchlevelslightly.
Nomatterwhichwayyouadjustthelevel,doitinverysmallsteps,sincethissettingisfairlycritical.
FIELDUSE
Thedetectorshouldbeheldinapositionthatiscomfortableforyou.Swingthedetectorfromsidetosideinaboutathree
footarc,overlappingsucceedingstrokeswell.Thismotioniscalleda“sweep.”TheGoldenSabreIIwasdesignedtoget
maximumdepthwithoutthefranticpacerequiredofearliermotiondetectors,sogoatapacethatiscomfortableforyou.In
fact,tryingtohunttoofastinDiscriminatemayevencausealossofdepthinheavilymineralizedlocations.
Itwouldbehelpfultoburysomecoinsandtrashmetaljunkitemsinanareathatyouknowisclearofothermetal
objects,andthentrytheunitinitsvariousmodes.ChecktheareainAllMetalModefirsttobesureitsclearoftrashthen
burythetargetsatleastafootapart,andfrom2to6inchesdeeptostart.Makeamapofthetestbed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learnthepropersweeprateforbestoperation.
Regardlessofwhichmodeyouareusing,trytokeepyoursearchcoilheightconstantandclosetotheground.Most
peopletendtoraisethecoilattheendofasweep,muchlikeapendulum,especiallyiftheyarehurrying.Trytoavoidthis,as
anyincreaseinheightwillcauseacorrespondinglossofdepth.
Inareaswithwellkeptlawns,theeasiestwaytomaintainaconstantsearchcoilheightistoallowthecoiltorestonthe
grassasyousweepfromsidetoside.Inroughandrockyareasitisbestnotto“scrub”thecoilontheground,astherocks
willactlikeabrasives,andwearawaythecoilbottom(anoptionalcoilscuffcoverwillprotectagainstthis.)Sweepthecoilas
closetothegroundaspossiblewithouttouching.Hittingthegroundorrocksmaycauseafalsesignalmuchlikeadesired
targetwould.Sweepingthecoiltoohighabovethegroundresultsinalossofdepth.
WhenoperatingintheDiscriminateMode,some“falsesignals”maybecausedbyheavyconcentrationsoftrashmetal
objects,byverylargetrashitems,orbyelectricalinterference.Thesesignalswillsounddifferentthangoodtargetsignals
becausetheyaregenerallyshort,choppysounds.Attheendofyoursweep,asyouthereversethecoildirection,the
detectorismostsusceptibletotrashinducednoise.Therearetwowaystotellwhetherthesesoundsaregooddeepsignals
ortrash“noise.”Thefirstisbyrepeatability.Trashinducednoiseswillnotberegularasyousweepthecoiloverthesuspected
targetseveraltimes,whereasagoodtargetresponsewillberepeatable.ThesecondmethodistoswitchtoAllMetalMode
andcheckthetargetresponsesound.Iftheresponseisweak,itmaywellbeadeep,goodtarget;butiftheresponseisvery
strong,itisprobablytrash.Notethatacoinclosetothesurfacecangiveadoublebeepsound,butitisregularand
repeatable.Raisingthecoilaninchortwowillrestorethesinglebeeponsurfacetargets.Raisingthecoilaninchortwowill
alsomanytimescausesurfacetrashfalsesignalstosuddenlydisappear,whilegoodtargetresponsesjustbecomefainter.
Ifthetrashinanareaissoheavythatyouaregettinglotsofchoppysoundingfalsesignals,itmightbegoodtochange
toasmallercoil.Ifthisisn'tfeasible,youcanprobablygetbetterresultsbyslowingdownyoursweepspeed,andusing
shortersweeps.Itwouldbegoodtohunttheareatwice,thesecondtimeatrightanglestothefirsttime.Thistechniquewill
probablyallowdetectionofsometargetsthatwerehiddenbytrashthefirsttimeduetothesweepdirection.
Ifthereisanydoubtwhetheratargetisgoodornot,DIGIT.
Ifyoudon'tdiganyjunkatall,youaresurelypassingupalotofgoodfinds,too.SettheDISCLEVELonlyhighenough

PINPOINTING
ThesweepspeedoftheGoldenSabreIIisslowenoughtoallowpinpointinginthe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slowingthesweepspeedwillnarrowdownthedetectionareaenoughthatit'seasytotellwherethecoilcenterisatthe
instantofthesound.
Anothereasymethodistosweepthecoilfromsidetosideacrossthetarget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.Infact,youwillbelookingatthe
exactspotinthegroundwhereyouwanttodig,becauseoftheopencoilcenter.
TheeasiestwaytopinpointformostpeoplewillbetoswitchtotheAllMetal,sincenomotionisrequired.Topinpointa
targetthatdoesn'tsaturate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center.Iftheaudiosaturatesoveralargearea,simplypushthemodeswitchtothe
retunepositionmomentarilyovertheareatoretunethedetector.Thiswillnarrowitsfieldofresponsetoallowyoutoonce
againseektheareaofstrongestresponse.Itmaybenecessarytoretunemorethanoncewiththistechnique.Witha

Overview

1. Function Description
2. Usage Features
3. Maintenance Features

The TESORO Metal Detector, specifically the Golden Sabre II model, is a high-performance VLF (Very Low Frequency) metal detector designed for treasure hunting. Its primary function is to detect buried metallic objects while simultaneously rejecting ground mineralization and metallic trash. The detector is engineered for ease of use and high performance, minimizing complex adjustments that could lead to a loss of detection capability if not used correctly.

Function Description

The Golden Sabre II operates with Notch Discrimination, a key feature that allows it to reject common metallic trash items like pull tabs without sacrificing the detection of valuable targets such as nickels and small gold rings. Alternatively, it can be configured to detect only a specific band of desired targets. The Notch Tone Target ID system provides a distinct low tone for targets below the Notch Level setting and a higher tone for targets above it, aiding in target identification before digging.

The detector offers two primary operating modes: All Metal and Discriminate.

• All Metal Mode: This is a no-motion, automatic-tuned mode that utilizes an internally fixed threshold sound. It is particularly useful for relic, cache, or nugget hunting. The ground rejection in this mode is internally preset to be slightly positive, meaning the threshold sound will increase when the searchcoil is lowered to the ground. All other features like notch tone target ID and notch filter are not active in this mode, and the audio sound is always the lower of the two notch tones.
• Discriminate Mode: This is a motion-based mode, requiring the searchcoil to be moving slightly for target detection. There is no threshold sound in this mode. The Notch Tone Target ID features are active, even if the notch mode switch is in the off position. The notch level control determines whether a target indication is a high or low tone, with targets having a phase response below the notch level setting producing a lower tone "beep" and those higher than the setting producing a higher tone "beep." This mode is ideal for coinshooting and general treasure hunting where trash rejection is important.

The Silent Search discriminate mode is motion-based, meaning the searchcoil must be moved slightly to detect a target. Despite this, pinpointing is still possible within this mode. A no-motion pinpoint mode is also included, which, especially with the 8-inch open center searchcoil, simplifies the pinpointing process. The automatic ground rejection circuitry is designed to allow operation in virtually any mineralization, though challenging conditions may arise in black sand. The detector incorporates Tesoro's advanced High Gain Sensitivity circuitry, which enhances depth in various environments and improves sensitivity to smaller, less conductive targets like gold jewelry. An expanded discriminator further refines selectivity for hard-to-identify targets that previously could only be detected in All Metal mode.

Usage Features

The Golden Sabre II is designed for user comfort and efficiency. It can be assembled in two configurations: pole mount or body mount, with easy conversion between the two. The lower pole and coil installation remain consistent for both setups. The control housing, when pole-mounted, is already attached from the factory, requiring only the searchcoil connector to be inserted and tightened. For body mount, the control housing is removed from the upper pole, and the searchcoil cable is clamped with Velcro straps. The armrest can also be adjusted for optimal comfort.

The detector features five front panel controls and a rear panel threshold adjust. These controls are easily accessible with the index finger of the hand holding the detector.

• ON/OFF, BATTERY TEST, SENSITIVITY CONTROL: This control turns the detector on and off. When first turned on, it performs an automatic battery test, providing an audible indication of battery connection. Its primary function is to adjust the detector's sensitivity, reducing interference in difficult operating conditions. It's recommended to run sensitivity as high as possible for smooth operation.
• SEARCH MODE SWITCH: This toggle switch selects between All Metal and Discriminate modes.
• DISCRIMINATE LEVEL: Used in Discriminate mode, this control adjusts the detector's response to unwanted metallic trash. At its lowest setting ("0"), most iron objects are eliminated, while light foil, bottle caps, and other metallic items still elicit a positive response. As the setting increases, more trash items are rejected. Users are encouraged to test their detector against various targets to understand its rejection levels.
• NOTCH MODE SWITCH: This toggle switch selects the function of the notch filter in the discriminator circuitry. In "reject" mode, targets within the notch are rejected. In "accept" mode, only targets within the notch are detected. The notch width is factory-set to reject common pull tabs and lift tabs. In the center position, the notch filter is disabled.
• NOTCH LEVEL CONTROL: This control adjusts the notch filter response to the desired target level in notch discriminate modes. It should always be set higher than the discriminate level by at least one full increment for proper operation. It can also function as a tone control if the notch filter is not used, indicating targets below the notch level with a lower audio tone and those above with a higher tone.
• THRESHOLD CONTROL: Located on the back panel, this control requires minimal adjustment. Once set to a barely audible tone, it typically doesn't need frequent resetting.

For optimal use, the detector should be held in a comfortable position and swung from side to side in a three-foot arc, overlapping strokes. Maintaining a constant searchcoil height close to the ground is crucial for maximum depth. In well-kept lawns, the coil can rest on the grass, while in rough areas, it's best to sweep without touching the ground to avoid abrasion.

Pinpointing in Discriminate Mode requires practice, involving slow, short sweeps over the target to narrow down the detection area. The open center searchcoil simplifies this by allowing the user to see the exact dig point. For easier pinpointing, switching to All Metal mode is recommended as no motion is required. The detector can be retuned momentarily to narrow its field of response for precise target location.

Maintenance Features

The Golden Sabre II is a precision electronic instrument designed for longevity with proper care.

• Battery Replacement: The detector uses 8 AA penlight batteries. To replace them, the large knob on the battery door at the rear of the unit is pulled, and the entire door pops out. Battery packs are then removed, new batteries inserted with correct polarity, and the packs slid back into the detector. The battery door is then reinstalled and locked in place. It is recommended to use good quality alkaline batteries and replace all of them at the same time.
• Storage: For long-term storage, it is best to remove the battery pack to prevent internal damage from potential battery leakage.
• Searchcoil Care: The searchcoil is waterproof and can be submerged in fresh or salt water. However, caution must be exercised to prevent water from entering the chassis, which could damage the electronic circuitry. After use in salt water, the coil and lower stem assembly should be thoroughly rinsed with fresh water to prevent corrosion.
• General Care: Treat the detector with care to ensure years of reliable operation. The unit is designed to withstand normal use but should not be abused, altered, or repaired by unauthorized parties.
• Cable Management: When converting between body and pole mount, ensure the searchcoil cable is wound tightly enough around the pole to prevent it from flapping, which could cause false signals. Spreading the necessary flexing over a large area, rather than creating a sharp bend at the cable clip, will extend the cable's life in body mount configurations.

Tesoro Metal Detectors are sold through independent dealers, who are often treasure hunters themselves and can provide valuable information on detector use, probing, digging, and local treasure hunting. Using earphones is highly recommended as they block ambient noise, allowing fainter signals from deeper targets to be heard more clearly, and they significantly extend battery life. The Golden Sabre II includes a limiting circuit in the earphone jack, and earphones with built-in volume control can be used if less volume is desired.

The manufacturer emphasizes the importance of responsible treasure hunting, including obtaining permission before hunting on private property, schoolyards, parks, churches, or state parks. Users are urged to "NEVER LEAVE A HOLE!" and to always fill their holes to protect the hobby.
