Reminder: The site is complex. Once the pinpointer alarms everywhere and
appears self-excitation, it should balance again. You should pay particular attention
to the change of the color of the LED and the vibration frequency when you
determine the position. If the frequency turns higher, the LED glows white light
the distance to the target object will be more nearby. In order to improve the
positioning accuracy you also can detect in the cave after re-balancing.
4. You can be assured that the pinpointer will work well in the underwater only
keeping the depth the depth is not more than 10 meters .Of course, you should
check and make sure the time to change batteries, the O-type rubber ring on the
battery cover is placed well and the battery cover should be fasten tightly.
5. For the pinpointer use as a non-motion metal detector you can use as a small
detector in the home .Of course, it cannot distinguish the metal types but only can
find whether there are metals. You can scan on the wall, ceiling and plaster both to
find and to detect the position of the screw, metal pipe, switch box and other metal
objects.
