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.
Remind you once again,when detecting in the wild,due to the impact of the
ground condition,the discrimination indication and depth indication will be all
deviation.The composition,size and oxidation of the metals will all affect the
indication result.It’s necessary for you to consider these factors before
choosing elimination a certain metal or determining whether there are
precious metals present.Not to eliminate the precious metals
8. The use of the non-motion mode.
In fact,the sensitivity in the non-motion mode is high,search metals directly
using non-motion mode is also a choice.In some regions,the ground is too
narrow to sweep search coil,you could choose the PINPOINT mode.In the
severe mineralization or salinization region,you could try to sweep using
PINPOINT directly.
Caution
1) In areas with heavy traffic,please not wear earphone,in case an accident
occurs.
2) Always obtain permission before searching any site.
3) Keep away from the region where may bury electrical line,cable line or
pipeline,in particular the pipes that are full of flammable gases and liquids.
4) Do no detect in the military area where may bury bombs or gas
explosives.
5) When excavating the target,use the reasonable method,not destroy the
vegetation.Leave the land and vegetation as it was,fill in the holes after the
excavation.
SYMPTOM
SOLUTION
No power,no boot sound,and the
LCD has no indication.
1.Be surer that the batteries are
installed correctly.
2.Be sure that “UP” on the battery
cover towards up.
