Echofish 300 sonar
technology is based on
sound waves. The system
uses sonar to locate and
define structure, bottom
contour and composition, as
well depth directly below the
transducer.
The transducer sends a
sound wave signal and
determines distance by
measuring the time between
the transmission of the
sound wave and when the
sound wave is reflected off
an object; it then uses the
reflected signal to interpret
location, size, and
composition of an object.
A simple menu system accesses unit's adjustable
features.To activate the menu system,press POWER-
MENU and a menu appears.Press POWER-MENU
repeatedly to access other menus one at a time.When a
menu is on the display,use the right and left arrow keys
to adjust the menu.Menus automatically are removed
from the screen after several seconds.
