7 Echosounder
The Echosounder is a high quality, dual frequency fishfinder. An
ultrasonic pulse from your hull-mounted transducer travels down
towards the bottom and spreads outwards into a rough cone
shape. Depth to a target or the bottom is found by measuring the
time taken between sending the pulse and receiving the echo.
The Echosounder pane shows the most recent echo on the extreme
right of the pane, with the earlier echoes (the history) scrolling to
the left.
Factors such as the clarity of the water and transducer type can
affect the appearance of the
Echosounder pane.
The Echosounder is supplied with default settings, but you can
customize many of these to suit your own preferences.
Depth soundings should be used only for navigation. Never
use a depth sounding to gauge depth or other conditions for
swimming or diving.
