How Fish Finders Work?
A Fish Finder is a subset of a group of instruments
called Sonar.
The Sonar is made up of a transmitter, the transducer
receiver and display.
In its simplest form, an electrical impulse from
a transmitter is converted into a sound wave from the transducer
and sent into the water. When this wave has hit an object, it bounces.
The frames echo transducer, which converts them into an electrical signal,
which is amplified by the recipient and sent toshow.
Because of the speed of sound in water is constant (about 4,800 meters per second)
the period of time between the transmitted signal and the echo received can be measured
and the distance of the object specified. This process is repeated many times
second.
DISPLAY:
The display shows a history of eco received. The user can set a series of
adjustments to adapt the display of his choice, as senitivity,
depth and diversitypaper speed. Show use a variety of techniques,
offers various resolutions, and the number of grayscale or color. Each panel
includes a number of pixels, which are small rectangular blocks from which the pictures.
The largest number of pixels and gray scale or color resolution of better quality and clarity of images.
Fish Goal:
Echoes of fish in the package will be displayed at the pixel indicated is displayed.
What image appears on the screen depends on a number offactors: the sensitivity
Fishfinder setting, the cone angle of the transducer, the speed of the boat,
and size, depth, speed and direction of the fish. A fish that swims directly
During the boat, it will create a consistent echo that an unbroken line that will cause
displayed. A stationary fish caught in a narrow beam transducer appears
as a single point on the screen when the boat approached, while
conditions for fishappears as an arch if a wide beam transducer is used.
