TREAS(TRE HIJNTER'S CODE: OFETHICSAll treasure hunters might be Judgedby the example you set Here are a fewbasic rules you should follow whileusing your detector Always get permissron before

searching any site Respect the fights and property ofothers

Observe all national, state, andlocal laws while treasure huntmg

Never destroy historical orarchaeological treasures If youare not sure about an object yourhave found, contact a museum orhistorical society in your area.

. . ._.....,_ O ' f tUSING HEADPHONES

You can connect a pair of stereoheadphones .(not supplied) to thedetector so you can listen to i tprivately. Using headphones alsosave battery power and makes iteasier to identify subtle in thesounds you hear, for betterdetection results.


7/16

To connect headphones to thedetector, insert the headphones'1 /8 inch plug i 11 tO the headphonejack on the side of the controlhousing.The detector's in ternal speakerdisconnects when you connectheadphones.

Listening SafelyTo protect your hearing, followthese guidelines when you useheadphones. Set t he volume to th e lowest

setting before you beginlistening. A [ter you beginlistening, adjust the volum eto a comfo rtab le le vel.Do not I istcn at extremelyhigh volume levels.Extended high volumelistening can lead top erm an en t hearin g loss.

O nce you set the volume, donot increase it. Over lim e, y ou rears adapt to the vo lum e lev el,so a volume level that doesn'tcause discom fort m ight stilld am ag e your hearin g.

INTRODUCTION OF OPERATION BUTTON

ZEROING BUTTON7eroing Button is at the forefinger'sposition when holding the detector.Press it, the pointer of the-viewrneter returns to "0" position.

Zeroing Button has memoryfunction, so it can memorize theworking circumstance at workingtime. For example, while holdingthe search coil over the ground, theground emits signal to make thepointer leave . O"poSiliolt, you canreturn it to "0" by pressing theButton again. Then you can begindetecting.Don't press the Zeroing Buttonnear metal, or the detector can notdetect metal any longer.What must be pointed out is thatyou must press the Zeroing Buttonbefore adjusting any other tumbutton, then relieve it after finishingadjusting.

7.

During detection, with thechanges of environment, thepointer often leaves "0"position. Pressing Zeroing Bullonto return the pointer to "0", so youmust often press it during thedetection process.The detector need about oneminute to preheat after turning onthe detector, or the pointer willleave "0" after pressing theZeroing Button. All will benormal after preheating.

TUNE TURN BUTTONAdjust the TUNE, the sound risesslowly, the sound which just canbe heard is called "critical sound" ,The detector has the highestsensitivity when it is at "criticalsound".


9/16

Note:Press the Zeroing Buttonbefore adjusting the "criticalsound" and set free it afteradjusting.If the "critical sound" rises.falls. or disappears. set it byprcssiug the Zeroing Bulton.SENSITIVITYBUTTON

TURN

Sensitivity Turn Button controlsthe sensitivity of the detector.

SENSITIVITY(fj)M IN MAX

Rotate it counter~clockwise tothe end point, the sensitivity isMlN and the detection depth isMIN; rotate it clockwise to theend point. the sensitivity is MAXand the detection depth is MAX.To set sensitivity depends onthe testing circumstance. but notthe higher, the better,

For example, in those heavymineralization area, high sensitivitycauses false signal, the detectorsounds everywhere so that thedetector can't find target correctly;'In such condition, lower thesensitivity to reduce the effectcaused by complex soil; in thosepure area, the higher the sensitivity,the stronger the detection.Note: Press the Zeroing Buttonbefore adjusting the sensitivity andset free it after adjusting.GROl)ND BALANCE TURNBUTTONOwing to The "mineralizationreaction". the search coil of old-style metal detector emits fals.esignal. and the "critical sound" isaffected by the change of thedistance between the search coil andthe ground, so you can't distingul.the type of the signal (minerlizalioQsignal or metal signal). To salvesuch problem, Ground Baia'nc::eCircuit is designed 10 decreasethe "mineralization reaction" to thelowest.

Notes: The search coil will not detectwithout motion. You must movethe object since you are notsweeping with the detector atthis time.

If you are using a coin. thedetector detects it more easily ifyou hold it so a Hat side (not theedge )is parallel with the nat sideof the search coil.

OUTDOOR TESTING AND USEI. Find an area on the ground outsidewhere there is no metal.

2. Place a sample of the material youwant the detector to find (such as agold ring or a coin ) on theground., (If you are using valuablemetal such as gold to test thedetector, mark the area where youplaced the item, to help you find itlater. Do not place it in tall grass orweeds.)

3. While holding the searchcoil level and annul kinches above the ground,slowly move the search coilover the area where youplaced the sample, sweepingthe search coil ill a side-toside motion.

4. Try finding other metal inthe area. When you rind ametal item, wait a fewseconds after the tone stopsbefore continuing, to allowthe detector time to reset (or,press the Zeroing Buttonto return the pointer to "0"position).

The search coil's plug should henot affected with damp. or thedetector will loss detectionability; the plug can be usedonly after drying III suchcondition;

The detector IS prohibited towork in rainy day and IIIburning sun;

The search coil should he faraway from furnace and otherhigh temperature circumstance;

Each detector is attached apiece of guarantee and it is freeto be repaired during the lengthof warrantee unless he circuit ischanged by user himself.
