Humminbird 300TX Fish Finder User Manual


 
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 300TX alarms on
only those targets that are represented by the large fish symbols. The 300TX 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 300TX emits an audible beep when the selected
size fish symbol appears on-screen. The sound is slightly different for each of the three
fish symbol sizes, so with practice, it is possible to distinguish the size of the detected
fish without looking at the unit.
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 300TX, 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 300TX 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 the 300TX is
operated from a battery source, the voltage number can be used to determine battery
life. The 300TX will operate at voltages from 10 to 20 VDC. Voltages in excess of 20 or
less than 10 VDC cause the unit to power off.
Options. The Options Menu is a series of linked menu functions used initially to set
your preferences. Once you preferences are selected, it is unlikely these functions
need to be accessed during the normal operation of the product.
The Options menu works differently than other menu functions in that all the options
must be cycled through in order to return to normal operation. There are seven Option
menus: Units, Fish ID, Numeral size, Bottom Black, Diagnostic and Reset.
Units Speed. The Units Speed function allows the user to select the units of
measurement for the speed readout. Both MPH or statute mils per hour are available.
The 300TX remembers this selection even when the unit is powered off.
