In getting the accurate picture bottom contour, making sure in reeling or trolling in finder at steady, slow speed. Depth scale at right of screen will enables one in identifying depth at any features. The reading in top right in screen show one bottom depth just under the finder, bearing at mind that not is necessarily same depth and that would call the depth finders.
Most units have gain or sensitivity control is of automatic feature. Computer would interpret the information receives and adjusting the sensitivity down or up, in giving the clearest of picture possible. In getting most of the unit at putting of sensitivity on manual could be achieved. Slowly turning the sensitive level up just a little till the false bottom or second echo reading would appear.
At modern system some transmitter that supply the powerful pulse in electrical energy then the transducer will convert pulse in acoustical pressure in water then receive the echo then convert that back to electrical that could amplified then applied to indicator. An audible frequency that is less than fifteen kilohertz is employed. Basic principles that used in those early devices have been no changed.
If it is installed properly and functioning then it shall produce a lot of information just for any angler. The finder works through sending electrical impulse that comes from transmitter then converting that in sound wave via transducer, sending sound wave in water. That method is called sonar. When that wave strikes some object, it rebounds a signal in form of echo to its transducer.
The technology in fish finder was the first used at nineties and been has upgraded since. At modern times, it is developed in including the system like GPS, radar and electronic compasses, making device more reliable even before. And there is transmitter located in ship that sends signal in waves. It uses aspect of the echoes into reflecting back waves into transmitter. That reflected waves would be recorded and signal sent to screen.
The active one uses the receiver and transmitter. When those two are on same place is the mono static of operations. The receiver and transmitter are separated that is bi static operations. The transmitters are used and spatially separated and it that is multi static. Most of the sonar used are with same array that often in being used to reception and transmission.
Unlike single frequency, the digital or broadband technology, the chirp continuously be sweeping the spectrum to a lot of frequencies in long duration pulsing. An equivalent energy is hundreds of the times that is greater than single, fixed frequency pulse, the resulting more energy at target. That provides the huge advantages at detail, accuracy and resolution in much of greater depths.
In measuring that distance to object and time from the transmission of pulse into reception that is converted and measured in range through knowing speed of the sound. In measuring several, bearing hydrophones that is used and set measures relative time arrival to everything through measuring relative amplitude at beams through process. Using the array reduces spatial response that provides the cover systems.
They are ideal tools because of reading depth, watching finding underwater and bottom contour features. That information shall more be valuable in actually marking things. The sonar shall constantly scan that means the display keeping scrolling if it not moving. The stationary and bottom shall appear yet may not.
