5. PINPOINT
After you find a metal object, you can use P/P to pinpoint the target. Hold
down P/P button. LCD will display P/P and an icon of an eye. Slowly move
the search coil above the sound area. The detector sounds and the depth
indicator on the LCD displays the probable depth of the target. Then release
the button. Sweep the search coil again, keeping the same distance of
search coil, sound disappears. Hold down P/P again, closer the search coil
to the sounds area, the detector sounds again. Repeat the above steps until
the detector displays the stronger signal where the location of the target is.
TESTING AND USING THE DETECTOR
To learn how the detector reacts to different metal, you should test if before
you use it the first time. You can test the detector indoors and outdoors.
Indoor Testing and Use
1. Press POWER to power on the detector.
2. Follow the instructions described in OPERATION to set SENSITIVITY,
VOLUME and operation mode.
3. Place the detector on a wooden or plastic table, then remove any
watches, rings, or metal jewelry you are wearing.
4. Adjust the search coil so the flat part points towards the ceiling.
NOTE: Never test the detector on a floor inside a building. Most buildings
have metal of some kind in the floor, which might interfere with the objects
you’re testing or mask the signal completely.
5. Slowly sweep a sample of materials you want to detector to find (such as
a gold ring or a coin) 2-3 inches or more above the face of the search coil.
When the detector detects any metal, it sounds a tone and an arrow appears
below the target icon. Also LCD displays the depth of the target.
NOTE: If you are using a coin, the detector will detect it more easily if you
hold it so a flat side is parallel with the flat side of the search coil. A sweep
with the side of coin over the search coil might cause false indication and
unstable display of arrows.
