Analogue-Scope Function; Navigate Mode - Navman F400 Installation And Operation Manual

Analogue-scope function

The Analogue-scope function is available in
either the Echo or Autofish modes. This feature
displays an intensity graph of the current echoes
down the right hand side of the screen.
The information can be used to help determine
the type of bottom structure and the size of fish.
The strength of the echo is proportional to size
or number of pixels visible in the analogue
section of the screen. This feature will help to
determine the strength of the return echo from
the bottom and therefore how hard or soft the
bottom may be.

Navigate Mode

In this mode the depth, speed and temperature
are displayed in large easily readable digits. This
is useful when navigating to your favourite fishing
location.
To increase precision, the values are displayed
in 0.1 increments.
