 To setup required discrimination sector, press  , several 
times, select entry setup left discriminator border.  
You  will  see  a  VDI  digit  in  the  square  frame  above  the  left 
border of the discrimination sector.  
Use  buttons  and  to  change this  number,  moving  the  border  to  the

slightly aside from the assumed target location and press .  
Warning!    Avoid  turning  this  mode  on  in  the  zone  of  target  sensitivity  (put  the  coil 
rather far aside).  
Then  smoothly  pass  it  above  the  detected  target,  keeping  constant  distance 
from the ground. Sound signal volume and frequency will increase upon approaching the 
target, decrease upon...

Visual Identification Tool - Hodograph 
In  the  hodographic  image  mode  target 
information  is  shown  as  a  vector  on  the 
graph with axis Х and Y.  
Its  size,  form  and  angle  depend  on  the 
electric  parameters  of  objects  such  as 
conductivity,  magnetic  penetration,  depth, 
geometry etc.  
It  is  almost  impossible  to  describe  all 
nuances,...

In  second  case  (right  picture)  it  is  safe  to  say  that  there  is  a  flat  iron  target under the coil, a piece of iron roof coating, fragment of a kettle, for example.

You  are  likely  to  be  amazed  by  the  fact  that  most  devices  produced  worldwide 
have similar sensitivity, for example, to a brass disc with the diameter 25 mm and  a fifty...

 Make  additional  scanning  to  detect  object  type 
above  the  center  of  the  object,  i.e. on  the  maximum  signal 
line,  keeping  distance  between  the  searchcoil  and  the 
ground  if  possible.    For  the  same  purpose  it  is necessary to 
scan  found  object    in  the  direction  with  the  least  ground 
relief changes.  In  this  case  the  ground...

objects. 
If such target gives a strong response (rating 10 and higher), the searchcoil edge 
scanning  technique  may  be  applied.  With  this  scanning  technique  the  aforementioned 
targets would give low tone of sound indication, and the display would show specific shift 
of the hodographic picture to the left (to the iron sector). 
These targets may also be scanned by a...
