Zoom WS (Zoom weak signals) [1:2/1:4/1:7]. This option was designed to increase 
the capabilities of visual hodographic identification. It allows to increase sizes of weak signal 
hodographs as well as to evaluate the signal level by the size of the hodographic picture. For 
instance,  setting to  the 1:2 scale  you  can  increase  and  thoroughly...

these lower tones appropriately. If you perform a search in places where the medium/large 
iron can be interesting (Arrowheads, knives, medieval items etc.) you can move the non-
ferrous tone to the sector border where the majority of large iron indicates at -45 (-50 
possible maximum).

As we gain experience the company reserves the right, without notice, to change the value 
of the factory settings. 
             A  very  useful  practice  is  to  switch  between  user  modes  to  access  changes  in  menu 
options. A good example of this is changing “Backlight” settings. To do this there are a  pair 
of  identical  search...

REPLACING THE COIL 
Attention!  Before you replace the coil, find a clean section of ground, because after a 
coil replacement a ground balance is required. 
Or, if a clean place cannot be found, have a piece of ferrite, or use a piece of red 
brick. Secure the desired coil on the rod, wrap the wire around the rod and plug the 
connector into the...

               Use additional scans to more accurately identify the type of object by centering 
above the target. Sweep the coil through the maximum signal area as accurately as possible 
maintaining a constant distance between the coil and ground. For the same reason scan the 
target with coil in the direction of the least amount of surface change...

 ferromagnetic  objects  such  as  steel caps/stoppers,  lids,  cans,  etc.,  objects  with  a 
relatively  large  diameter of  the  eddy  currents.  This  is  largely  helped  out  by  using  our 
proprietary development – The Hodograph Display (see Fig. 19). 
In  the  interaction of such  objects with  the coil (assuming that  the  level  of...

The example in Fig. 25 shows a hodograph for two nearby objects. Dimensions of the 
Hodograph loops  will  depend  on  the  ratio  of  the  size  of  these  objects  and  the  distance 
between them....
