User Manual

a) Water depth: Depth detection ranges from 0.6 - 45m (2-135Ft), the precision is 0.1 m
(0.3 ft). Depth is expressed as one decimal point.
b) Water temperature：The detected temperature refers to the water surface temperature;
the temperature sensor on the probe keeps in touch with the water surface. The temperature
range is from minus 9.9 ℃ to 60.0 ℃, the precision is 0.1 ℃; the corresponding Fahrenheit
degree should range from 14.2° to 140°.
c) Calibrated scale: Based on this scale, the user can intuitively check the water depth
and the depth of fish group, and combine with the depth range to partially enlarge for use,
so as to achieve many ways for viewing,and maximally watch the interesting information
of fish group within the depth range.
d) Zoom upper limit: This value represents the currently displayed upper limit value, and
the value is jointly determined by the depth range and ZOOM. When the local zoom is set as
OFF, the upper limit value of zoom is 0; when zoom value is set as other values, the upper
limit value of zoom is equal to the difference between the lower limit value and zoom value;
when the lower limit value of zoom is less than zoom value, the upper limit value of zoom is 0.
e) Zoom lower limit: The value indicates the currently displayed lower limit value, and the
value is determined by the depth range. When the depth range of the parameters is set as
AUTO, then the value is not more than the current minimum value in the list of the water
depth range (the value is not more than the minimum value of current water depth range
among 1m-45 m); when the depth range is set as the other values, then the lower limit
value of zoom is the setting value; in other words, when the lower limit value of zoom is 5 m,
the content above 5m is only displayed.
