Soil density
conditionally shows the power of the reflected echo from the
bottom and can vary from 0 to 22 units. The larger the number, the higher the
soil density (the harder the bottom) and vice versa. With the same reflectivity
of the bottom, the density value will decrease as the depth increases, since
the signal weakens.
Screen scale (depth scale)
is how many meters of depth is shown on the
sonar screen. The letter "A" next to the number means automatic scale
selection; the letter "M" is manual scale (more details in the Scale section, p.
22)
Sensitivity indicator
–
the vertical bar visually displays a rough value of
sensitivity, and the number above the battery symbol indicates the exact
sensitivity level (in digits). Sensitivity can be adjusted in the range from 0 to 28
units. The default value is 10 units. The bar is displayed on the screen only in
work mode when the sensitivity adjustment is turned on.
RTS window
is the area of the screen (in FISH ID mode), in which all
registered echoes from the bottom and other objects are displayed without any
processing. Processed information is displayed in the main area of the screen.
(bottom line, bottom structures, and fish symbols).
Battery indicator
shows the current battery capacity. The battery
condition
can be estimated more precisely in the "Info" mode, where the battery voltage
is indicated in volts. The maximum battery voltage at which the sonar can fully
operate is 0.85 V.
