:Less than 270W
:Temperature：-15℃～＋55℃／Humidity：Less than 93% at ＋40℃
:Vibration Amplitude：±1mm at 2～13.2Hz、Acceleration：7m/s
:0～10.0kn
: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.
: All surroundings (360°), numerical values, and 32 point bearing display
: Max. 50 Layer (A numeric display shows five arbitrary layers.)
: 2m (Shallow-water mode)
: 12m (Std. mode)
: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.
: 5m
: 2～500m It is possible to set it arbitrarily.

Large one either ±1%rms or 0.1kn
: Ground speed measurement depth: 5～250m
: Water speed measurement depth: More than 10m
(Ground speed/Water speed simultaneous display)
Note: The measurement depth might be different according to the state of the
bottom.
