7) Current measurement performance
Current speed range
:0
～
10.0kn
Current measurement
accuracy
:Large one either ±2%rms or 0.2kn
Note: When there is a bubble right under transducer or the roll-pitch of the hull
is large, the unexpected value exclusion processing to keep the measurement
accuracy is done. However, when they are excessive too large, there is a
possibility that the direction and speed of the current is mis-displayed.
Current direction
display
: All surroundings (360 ° ), numerical values, and 32 point bearing display
Measurement layer : Max. 50 Layer (A numeric display shows five arbitrary layers.)
Minimum Measurement
depth of layer
: 2m (Shallow-water mode)
: 12m (Std. mode)
Maximum Measurement
depth of layer

:160m
: 100m
Note: The maximum value of measurement depth of layer is 80% or less of
depth.
%-value decreases as depth becomes shallow. Moreover, the maximum value
of the measurement depth might be different depending on reflection strength in
the sea.
