Instructions for use:
Thank you for choosing our Metal Detector MD-720. Please read this
manual carefully and become familiar with the function of M720
before use. After reading, please keep it safe for future reference. TIPS
1. MD720 is used for outdoors. There are too many interferences
indoors.
2. In the higher sensitivity range, the detector will be more
sensitive to the electromagnetic interference. By reducing
sensitivity you can get rid of interference.
3. When detecting, move the search coil at a constant speed. Let
the search coil be parallel with the ground and about 1/2 inch
from the surface, do not to swing it like a pendulum.
4. The depth indication is accurate for coin-sized objects. Large
objects or irregularly-shaped objects will reduce accuracy.
5. Most of the valuable metal objects will send consistent signals. If
the signal isn't consistent, it's mostly a false signal.
6. In order to save power and extend battery life, the backlight will
automatically turn off in about 10 minutes, whatever it is working
or standby.
7. The machine will automatically turn off when it is in standby
mode after about 15 minutes.
8. If the P-P(pinpoint) mode malfunctioned, sending a signal even
when not close to any metal , lift the detector in the air, press the
P-P key button once to solve the problem
