[RANGES]

you can customize the ranges to suit your needs, with [RANGE 1] - [RANGE 8]. Set
the ranges in descending order. Be sure that each range is higher than its preceding
range.

Interpreting the Display
Zero line
The zero line (transmission line) shows
the position of the transducer. The line
disappears from the screen when the
range is shifted.
Bottom echoes
The strongest echoes are from the bottom, and are normally shown in reddish-brown
or red. The colors and the width change with bottom material, depth, sea condition,
installation, frequency, pulse length and sensitivity.
