 This  may  also  lead  to  targets  air  testing  as  iron,  as  well as a false  increase  in 
sensitivity when air testing.  Remember that for every 1 degree of ground balance offset from the 0 or 
neutral point we get a corresponding increase or decrease in the VDI scale for a 
given target. IE a 1 degree+ ground balance will increase the VDI by...

If  it  makes  sharp  angles  or  is  “chaotic”  on  the  screen,  this means  that  you  are  trying  to 
balance near a metal object in the ground. In this case, the device may perform a ground 
balance, however it  will  be  incorrect and  you will  notice  multiple false signals  from  the 
ground.  If  this  occurs,  simply  re-balance  the...

              degrees. If you encounter this problem then perform the ground balance procedure 
as follows.                                  
  Find a clean patch of ground with a width of 60 centimeters. Switch to manual ground 
balance and making short horizontal search sweeps with a width of 50cm at a height 3-5cm 
above the ground, you will see a...

 To configure the discrimination, click.             Now, by positioning the left and right 
edges of the search sector you can set the desired area (level) of discrimination. 
 
At the top left and top right of the screen are the current values of the search 
sector. These are in degrees of inclination relative to the vertical axis of the...

DYNAMIC AND STATIC MODES  Dynamic mode  is the main mode of operation of  the detector. It is characterized 
in  that  the processor constantly  adjusts  to  relatively  slow  changes  in  ground  conditions. 
Therefore,  in  this  mode,  the  instrument  responds  to  the  desired  objects  only  when 
moving  the coil.  If  the coil is stationary...

Then move the coil away from the target perpendicular to the primary direction 
(A) scanning (e.g. forward) along this line. 
 
This retraction of  the  coil in  this  direction must  pass  through  the original coordinate. Re-
enable the static mode. Scan the object along the line as accurately as possible keeping a 
minimum  distance between  the...

There  is  no  need  to  use  this algorithm  for  a  definitive  low-pitched signal, i.e. 
when  the  subject  is  clearly  iron.  Remember  though,  to  monitor  the signal  rating level  of 
the target. 
It  should  be pointed  out  that this  mode does  not  apply to general searching, but 
only to help clarify the type of metal of a...
