Fish Alarm. The Fish Alarm alerts you to the
presence of fish, or other targets not connected to
the bottom. The Fish Alarm has three different
settings that correspond to the three different size
fish symbols shown on-screen.
The default setting is “OFF.” With the “Large fish
only” setting, the 250DX alarms on only those
targets that are represented by the large fish
symbols. The 250DX can be set to alarm on only
large and medium fish, or set to alarm on all fish.
Once the Fish Alarm is enabled, the 250DX emits an
audible beep when the selected size fish symbol
appears on-screen.
Triplog. Triplog provides a running log of
information based on input from the Temp/Speed
sensor.
Since Triplog requires information from the
Temp/Speed sensor to operate, if this sensor
is not detected by the 250DX, the Triplog menu will not appear as
an option.
Triplog provides seven pieces of information: the current digital depth, water
surface temperature, current boat speed, the distance traveled since the 250DX
was powered up or reset, the average speed, the total time elapsed since
power-up or reset, and the input voltage from your boat’s electrical system.
The time, speed and distance calculations are useful for tracking your progress
on a trip. The input voltage is useful for determining the condition of the
charging system of the boat. When used in a portable application or whenever
