UNDERSTANDING SONAR
If you are familiar with the manipulation of a sonar, please
skip to the next section. However, if you have never owned
any sonar fishfinder yet, this section will teach you the basic
theory about sonar.
Based on the sonar technology, the Echofish 820 fish-
finder can detect
the
underwater conditions, including
fish presence or bottom structure. The transducer sends a
sound
wave signal into the water in
a
cone shape. At the
source,
the
wave is narrow; however as
it
penetrates
deeper, the
sound
wave spreads forming a
cone
(i.e
flashlight). The sound wave bounces back to the
transduc-
er
when it strikes any object. The object can be a fish, the
structure, the bottom or any other object with a different
density from the water.
The transducer amplifies the return signal and sends it
back to
the fishfinder
. By measuring the time between the
sound wave transmission and its bounce, the fishfinder can
calculate the distance thanks to the inner microproces-
sor. T h e
fishfinder
displays the information on the screen
for your interpretation.

No Skipping Detection
Your fishfinder integrates a high detecting technology. Real-
ly precise, it enables a “No-skipping detection”.
When the sonar works, it continually samples the echo at
same interval (for your fishfinder, it is 0.06 ms). T he
continuous signals
form
different sampling
points. The
shorter the
distance between
2 sampling points is, the more
precise your f ishf ind er is. Even small size objects can be
detected.
