Item Description Available settings
Ship’s Speed
Average
Set averaging time for ship’s speed. The default
setting is acceptable for most conditions. If the speed
indication is unstable, select the setting that gives
stable speed data.
5s, 10s, 15s, 30s,
60s
Current
Average
Set averaging time for current (tide) speed and direction.
The default setting is acceptable for most conditions. If the
current data changes randomly, select the setting that
gives stable current data, but does not slow response to
changes in current data.
1min, 2min, 3min,
5min, 10min
Track
Depth
Set the water tracking depth for measurement of through-
the-water-speed. If the through-the-water speed readout is
unstable, raise the setting.
0.5 - 25.0(m), 0.1m
steps
Current
Measurement
Set the depth at which to measure current (tide) speed and
direction.
0.5 - 25.0(m), 0.1m
steps
CALC
Average
Smooth the heading data, which is received every second. No Averaging, 10s,
30s, 60s, 90s, 120s
IR Turn the interference rejector on or off. Turn the rejector on
when an echosounder is connected to the DS-60, to
prevent mutual interference.
