Trip Log or Total Log. Both logs are retained in the
FISH 4200 memory when the unit is switched off.
Use the SETUP - LOG menu to select the Trip Log
or Total Log (see section 4-6). The Trip Log must
be reset manually (e.g. to record total mileage
during a season, or the distance travelled on this
trip). Note that the units displayed on each Log will
correspond with the Speed.
Speed can be displayed in knots (KN), miles per
hour (MPH), or kilometres per hour (KPH). Use the

FLOW shows the fuel consumption per hour. For twin
engine installations the fuel flow for each engine is
shown separately. This is useful for checking that
both engines are under the same load.
ECONOMY is the distance travelled per unit of fuel
used. The NAVMAN fishfinder calculates this from
the boat speed and fuel used. The bigger the
number, the better the fuel economy. Adjust the
throttle and trim to achieve the best fuel economy.
SPEED is the current speed of the boat.
The water depth and the enabled alarms are shown
at the base of the screen.
Fuel economy can change drastically
depending on boat loading and sea
conditions. Always carry adequate fuel for
the journey plus a sufficient reserve.
Each time fuel is added or removed use
the fuel setup menu (see section 4-7) to
record the fuel or else fuel remaining and
the low fuel alarm will be meaningless!
