Understand sonar
If you are familiar with how sonar works, skip ahead
to the next segment. But, if you have never owned
sonar Fishfinder before, this segment will tell you the
basic working theory about sonar.
Based on the sonar technology, the Fishfinder could
detect the underwater condition, including fish,
structure, or bottom. After you finished the
installation of transducer and sonar unit, connect the
sonar unit to the transducer. 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 (think flashlight). The sound wave bounce
back to the transducer when it strikes any object, the
object could be fish, structure, bottom or any other
object with density being different from the water.
The transducer amplifies the return signal and sends it back to the Fishfinder. By
measuring the time between the transmission of the sound wave and when the sound
wave bounce back, the Fishfinder could calculate the distance by the inner microprocessor.
Then the Fishfinder display the information on the screen for you to interpret.
No-skipping detection
Adopted high detecting technique, your fishfinder
has a high detecting precision, which enable a
“No-skipping detection”.
When sonar works, it continually samples the echo at
same interval (for your fishfinder, it is 0.06ms). And
the continuous signals form different sampling point.
The shorter the distance between 2 sampling points
is, the higher precision your fishfinder will be able to
detect minimal object (thinking about the fishing net,
the smaller the hole is, the smaller fish that not being
able to leak).
