Afteryouhavedetectedthepresenceofatarget,holdthelocatorverticallyandslowlymoveit
backandforthinan “X”patternwhileobservingthedigital readout.Thevalueofthenumber
willbehighestwhenthelocatorisdirectlyover
averticaltargetorovertheendsofahorizontal
target.The“X”pattern,asshowninFigure8,isidealforpinpointingsmallobjects.Byusingthis
technique,a1‐1/4inchPKnailburiedupto8inchescanbepreciselylocated.


If you are looking for a corner marker and detect two more signals in the same general area,
raise the locatorseveralinches above the ground or reduce the sensitivity setting.Any signal
thatdisappearswhenthelocatorisheldhigherorwhenthe
sensitivityisdecreasedisprobably
comingfromashallowtarget.AsshowninFigure9,thesignalfromarustyboltorothersmall
itemdecreasesmuchfasterwithdistancethanthesignalfromalargertarget,suchasa18‐inch
lengthof3/4rebarthatcanbelocated
atdepthsupto7feet.
