Special Features

This device has various special features and these features are effective and help to increase the capability of the device. The important special features of this device are listed below.

Down Imaging-The important and attractive feature of this device is the down imaging technique. This feature is very attractive and this feature is an important reason for the reputation of the device.  The down imaging techniques monitor the underneath region of the water and display these regions with high resolution.

Even the small branches under the water are displayed on the screen.  The depth of the entire system is also displayed on the screen and the depth of each fish is displayed separately on the screen.

Display-The display used in this device is black and white in color and this display is of high clarity. All the minute things underneath the water level are displayed in this display. The display is about 5-inches tall and the images are viewed with a resolution of 300x 300 pixels.

Since the display is colorless, it uses a 12-level grayscale to display the variations within the black and white colors. The display uses sonar technology for transmitting and receiving the signals. All the incoming signals to the display are viewed in the form of a 2D image instead of the 3D image.

Switch Fire Sonar-The next important advancement in this device is the use of the switch fire sonar. This sonar is very effective in determining the fishes beneath the water level. This sonar is operated in two modes, one is max mode and the other is the clear mode.

The clear mode modulates the incoming signal by eliminating all the minute disturbances within the signal. The max mode is of higher efficiency and it displays the entire signal without any modulation. Small branches of the system can be detected easily with this device.

Transducer-The transducer is a device used for converting one form of signal to another form of signal. In Humminbird 561, the transducer is used for converting the captured image signals and it is also used for transmitting these image signals to the receiver.

The receiver is the display unit and it also has a transducer for converting the signal suitable for viewing. The transducer displays the transmitted images without any loss and thereby, ensures high clarity of the displayed images.

Selective Fish Identification-Selective fish identification is also an important feature of this device and with this feature; the angler can identify the type of fishes crossing a particular region within the area. With this feature, the angler can select and catch the fish of their interest easily with high efficiency.  The main reason for the selective fish identification is  the quality and clarity of the device.

Split Screen-The display in this device displays the incoming signals on two different screens. These screens are based on the two modes of operation of the switch fire sensor. The displayed screens are also of higher clarity and this device also offers zooming phenomenon with this sensor.


The design of this device is simple and durable. This device resists water to a particular extent and can be used both in the salt water and fresh water. The coverage range of this device is about 850 meters and it can be used for detecting all the things beneath the water. This device is designed lightweight and hence, it can be taken everywhere. But once fixed in a boat, the portability of the device is less. Some anglers mount the device with the help of a screw and so, they do not offer portability.

How To Use?

This device is very simple and it can be used easily. It can be generally mounted in any places within the boat so that the anglers can see this device easily without any loss in their fishing. This device has a transmitter and a receiver with inbuilt sonar technology.

The transmitter is generally mounted beneath the ship and it has a high coverage area. The signals from the coverage area are received by the Humminbird 561 monitor and it displays the underlying region with high clarity. This process helps the anglers for various types of fishing.


This device is equipped with various accessories such as the mount. The mount is used for mounting the Humminbird 561 display unit in a perfect location. This region can be mounted without any loss thereby, increasing the efficiency of fishing. The transducer is also mounted beneath the ship with a transducer mount.
