two times
Small depth and dense
soil
Reduce sensitivity of
the device or switch
the device to “depth
meter” mode
4. The screen is
“sounded-off”,
too many objects
The depth reading is
changed chaotically
Big sensitivity is set;
“litter-out” reservoir
(much suspension, litter,
small fish, etc.)
Reduce sensitivity.
Increase “dead zone”

readings.
Absence of the
bottom line on all
the scales
Depth value or the
fish contour appears
sometimes
Depth under the sensor
is more than 25m or
very clay-covered
bottom. The depth
figures – distance to the
fish swum quite close to
the sensor
Transfer the sonar to
a more suitable place
(with smaller depths
corresponding to its
possibilities)
6. Chaotic
readings of the
depth on the
screen
The bottom line
disappears
The sensor is not fully
plunged into the water;
bubbles stack to the
sensitive area of the
sensor
The sensor must be
fully sank into the
water, and its surface
– free from the air
bubbles
7. Water drops
appear in the
battery
compartment
Image on the screen
may be unstable
The sensor was not

Dry out the battery
compartment. Locate
t he battery on a warm
