PHMD74 USER MANUAL
Metal Detector Owner’s Manual This metal detector has excellent sensitivity and intensive ability to identify and display six types of metals. It can indicate the material of the metal target through the latest patent design and the full digital location circuit, improved accuracy and stability of the location. In the field of electromagnetic interference, the full digital location circuit has good anti-interference ability. It will bring enjoyment of high-end products.
● Iron Iron is a common metal. It’s usually not the detection target, undesirable iron objects contains iron nail, bolts, old cans, caps and so on. But some valuable relics may also be made of iron, such as old ornaments, old armature and so on. ● Ferrous Metals which are made of, or contains iron. ● Trash metals Caps, pull-tabs, S-caps are the most bothersome trash items for treasure hunters; you should eliminate them during detecting.
● Power off prompt : sound a prompt tone every ten minutes ● Search coil: 210X70mm open waterproof search coil ● Earphone jack: 1/8 inch earphone jack(earphone not supplied) ● Power supply: 6 AA batteries (batteries not supplied) Note: When the power supply is switched on within a few seconds, the metal detector will go into self-inspection program. Don’t let the search coil approach the metal, nor carry out any operation, until the self -inspection is completed.
Assembly 1. Loosen the two triangular fasten buttons under the control box, insert to the bracket, and lock the two triangular buttons. See Fig.1. Fig.1 2. Press down the silver shrapnel on the plastic stem, and insert it to the black aluminum stem. When the silver shrapnel popping up from the black aluminum stem, you can use it.
Fig.3 Battery Use 6 alkaline AA batteries. 1. Press the “key” on the battery cover in the direction of the arrow, pull out the battery cover. Fig.4 2. Insert 6 AA batteries as indicated by the polarity symbols marked inside the battery box Fig.5 3. Close the battery cover. When a KATA tone being heard, which means the battery cover has been covered well. Ensure the direction of “UP” on the battery cover is followed. These batteries are expected to last for about 40 hours.
Panel and LCD All the controller adjustment displays on the LCD, and all the detection results are also shown on the LCD. LCD See Fig.6 Fig.6 ● Mode indication cursor: Indicate the four kinds of operation modes. Make a switch through the MODE button. ● Target ID pattern: It’s located above the LCD screen. It indicates the target metal you’re looking for. When detecting a metal target, the target ID cursor (upper scale) shows the metal patterns or the words.
● Target Digit Cursor: double digit, 10-99 indicates the material of the metal. When detecting, the digit may have some changes, which depends on the composition of the target, the size, the shape, the distance from the search coil and the speed of scanning. The surrounding soil can also affect the value. Refer to the following table as a preliminary guide.
● Sensitivity indication cursor: It’s divided into 4 gears, when they are all lighted; the sensitivity is at the highest. Adjust the sensitivity by the SENS button. It is useless in the PINPOINT mode. ● Battery power cursor: 3 gears indicate the battery power. When all the cursor is lit, this indicates power is enough. While the entire battery indicator is extinct and the battery pattern is glimmered, it’s time to replace the battery right away. Controller All the controllers are on the panel.（See Fig.
Press the MODE button again,logging out the memory mode,return to the state that all of the 6 lower cursors displaying,and carry on the second set.If no longer set,press the MODE button again,exit the MEMORY state,and enter the next operation mode. COINS- the detector eliminates the iron,pull-tabs and S-CAP,only be respond to all kinds of coins. ● SENS Button:choose the 4 levels with SENS button.Boot setting is at the middle value(the second gear).The highest sensitivity is the fourth level.
3. Turn on Press the POWER button,and the detector will sound two moo tones, all the LCD patterns will be lighted a moment,the detector will be in the operation mode by default,and the sensitivity will be at the second level.(See Fig.9) Note: Don’t let the search coil approach the metal,nor operate the detector,until the detector has the balance completed,and sound tweets. Fig.9 4. ALL METAL mode test Sweep the four metal samples 7 to 10cm above the search coil.
5. JEWELRY mode test a) Press the MODE “+” button again,the operation mode cursor points to JEWELRY,and the first target discrimination cursor at the lower cursor are extinguished. b) Sweep the four metal samples about 7 to 10cm above the search coil in turn. c) When sweeping the iron nail,the detector will not respond,meaning the “iron” is eliminated. d) When sweeping the other three samples,the response of the detector is the same with the ALL METAL mode.(See Fig.11,take 1￠ zinc coin as an example) Fig.
Fig.13 c) Sweep the four metal samples about 7 to 10cm above the search coil in turn. d) When sweeping the 25￠silver coin,the detector will respond,meaning the 25￠ has been remembered. e) When sweeping the other three samples,the detector won’t respond.(See Fig.14,take 25￠ as an example) Fig.14 f) If want to look for other materials,press the “MODE” button once again,so that the operation mode still points to MEMORY,and still shows figure 12.Then,repeat the above operation.
Fig.15 8.PINPOINT mode test a) Touch the “PINPOINT” button,the PINPOINT cursor is lighted and flashed.The PP cursor won’t flash until the detector has been balanced.The target ID cursor in the upper cursor and the target discrimination cursor in the lower cursor are all extinguished,and the depth cursor is full-scale,the detector will sound a slight single-frequency mediant.(See Fig.16) Fig.
c) Maintain the position of the silver coin,release the PINPOINT button,exit the PINPOINT mode.Press the PINPOINT button again after several seconds,the signal strength cursor is extinguished,and the sound comes back to the initial state,the depth indication comes back to the full scale.
3. Choose the sensitivity You always expect to set the sensitivity more higher.However,in the higher sensitivity range,the detector will be sensitive to the electromagnetic interference that comes from the power lines or cables around,and it will do abnormal reaction to the mineralization soil or electrical conductivity soil.If you move the search coil in the detection area,and the detector sends an unstable false signal,please decrease the sensitivity.
6. PINPOINT When detecting in the motion mode,as you should persistently move the search coil,so although you find the region that burying metals,it’s not easy for you to determine the exact location,it gets the digging difficult.At this time,you should recur to the PINPOINT mode. a) Touch the PINPOINT button,the PINPOIT cursor is lighted,and the depth cursor will be full scale.The detector will sound a low single-frequency tone,the sensitivity is in the highest state.
The above identification is only a reference,not completely accurate. The depth indication is accurate for coin-sized objects.Large objects or irregularly-shaped objects will yield less reliable depth readings.If sweeping at the same place for several times,but shows the same depth,then it is a more accurate detection.If the depth indication varies,try to change the angle of sweeping.There may be more than one target present.
TROUBLE SHOOTING GUIDE SYMPTOM SOLUTION Sound a successive “DI” “DI” tone 1.Make sure that there is no other metal detector operating around. The LCD displays normal,but the sensitivity is very low. 1.When turning on,there is metal near the search coil. 2.Let the search coil leave the ground, and then turn on the unit again. Sound an irregular tone,or the 1.Don’t use it indoors,because there is many metals there. target identification cursor chatters. 2.
