7FISH 4200 Installation and Operation Manual
An internal simulator allows users to learn how to
operate the fishfinder off the water.
In Simulation mode the word “SIMULATION” flashes
on the bottom of the screen. The fishfinder generates
data so that all the main screens appear to be
operational. Any changes made to the contrast,
backlighting, alarms or the display setup are saved.
NAVIGATE screen (see section 3-6)
Prominently displays the water depth as a digital
readout. The corresponding bottom trace is also
shown. These two complimentary features are
particularly useful for understanding depth trends
when travelling at speed.
It also displays the boat speed and the enabled
DATA screen (see section 3-7)
The DATA screen displays the water temperature
and water temperature history over the last 40
minutes. It also displays the boat battery voltage, log,
engine-hours counter, boat speed, water depth and
FUEL screen (requires optional fuel kit)
(see section 3-8)
The FUEL screen displays the amount of fuel used
and fuel remaining, and the rate of fuel flow. It also
shows the boat speed, water depth and an
ECONOMY reading, which 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.

Full Range Section which shows part of the
HISTORY Screen and to the left is the Zoom Section.
Use this screen for taking a closer look at interesting
SONAR screen (see section 3-3)
Displays the strength and depth of the echoes
returned from each ultrasonic pulse. The depth range

and the fish species.
This screen can also be used to adjust the display
shading on the HISTORY and ZOOM screens.
