Operation Instructions

1. Understanding the Fishfinder screen

This chart shows all the information your fishfinder can display
during the operation. The upcoming sonar information will
first appear in the Real Time Sonar window, and then scrolls
across the screen from right to left. So, what you see on the
screen (fish symbols, fish arches, bottom shape, etc) is
formed by the sonar history. The black line at the top of the
screen represents the water surface. You can also read the
following information: water depth, water temperature and
real time battery voltage.
By moving the transducer slowly at a steady speed, you can
see the bottom shape at the bottom of the screen.
