How to shorten pulse length

The pulse length determines the length of the transmission pulse emitted into the wa-
ter. While a longer pulse is advantageous for long-range sounding, it has the disad-
vantage of being poor in discrimination of targets, that is, the ability to separate several
closely located targets. When searching bottom fish, therefore, it is useful to shorten
the pulse length in order to separate fish echoes from bottom reflections.
Note: For search of surface and midwater fish in which bottom reflections are not so
strong, use the longest pulse length "9".
