probing  and  processing  considerably  differ  from  the 

depth  measurement  in  other  sonar  modes.  Depth 

measurement  for  the  difficult  condition  is  performed 

especially  precisely,  for  example,  fleet  water  and 

grown-over  reservoirs  may  be  referred  to  these 

conditions. None of the fish and any other date on the 

water depth is displayed. 

Any activities and adjustments on the part of the 

user  are  not  required  for  operation  in  this  mode. 

Sensibility  selection  as  performed  automatically 

depending on the reservoir conditions. The dead end is 

always adjusted as 50 centimeters. 

Diameter of the sonar spot at the bottom is measured in meters at the bottom of the cone 

base.  In  the  algorithm  of  calculation  of  the  spot  the  data  is  involved,  taking  into  account  the 

attenuation of the acoustic wave in the water, as well as numerous experimental data for sonar 

“Praktik”. In reality in the water the beam cone has the shape of the inverted flame of a candle, 

rather  than  the  usual  cone  with  the  angle  of  40  degrees.  It  is  necessary  to  clarify  that  such 

geometrical  parameters  of  the  sonar  beam  were  defined  by  us  specifically  for  practical 

applications, since in such beam focuses the maximum density of acoustic power, and the angler 

can clearly watch his bait (fishing tackle, plug, lure, etc.) on the screen.  

ATTENTION! The Depth gauge mode works correctly with inactive sensor/ otherwise the 

depth measurements will be unstable. 

Depth gauge mode is recommended in cases when in other modes of the sonar the depth 

reading is not stable on account of condition at the reservoir or confident depth definition with 

large numbers indication is required.
