To enable ZOOM, press the left button in work mode. 

 

When ZOOM is turned  on, the screen is divided by a vertical line into two 

equal  parts.  The  bottom  area  is  displayed  on  the  right  side,  and  the  usual 
processed or “raw” (depending on the selected display mode) information is 
displayed on the left along the entire route from the surface to the bottom. 

 

When the 

ZOOM mode is on, a magnifying glass icon with a number in the

 

middle appears in the upper right corner of the screen (instead of scale value). 
The  digits  in  the  magnifying  glass  icon  indicate  the  height  of  the  ZOOM 
window.  You  can  increase  and  decrease  this  value  with  the  up  and  down 
buttons (1, 2, 3, 4 or 5 m). 

 

To  change  the  ZOOM  window  width,  select  one  of 

the  values  in  MENU  in  the  ZOOM  window  section: 
normal, wide, or narrow. 

 

There are differences between the ZOOM function in 

WINTER and SUMMER modes. 

 

In  summer,  when  you  move  on  a  boat,  the  scale 

switches  when  the  depth  changes;  various  bottom 
structures  are  displayed;  the  ZOOM  window  can  be 
filled  with  bottom  objects  by  half,  or  even  more.  For 
this  reason,  it  will  be  problematic  to  get  useful 
information on the sonar screen. 

 

In  winter, the  ZOOM mode  is more in  demand in  a 

hole  in  stable  conditions.  The  bottom  of  the  screen 
corresponds to the bottom line, "frozen" at a depth, 
at which ZOOM was turned on.
