This is a vital component of a fish finder. The reason for this is because its function involves transmitting energy through the water before reaching a target, and reflects the beam back which is then processed by a fish finder. The final result is the image displayed on the screen.
For enhanced performance, you should select a fish finder with a multiple element transducer. This type of transducer allows for different elements to vibrate separately at their own frequencies.
2. Display ( size and resolution)
With the 5 inch screen, a user is able to enjoy a good view due to the display of the sizable images and data. This is a good screen size which will help protect your eyes against straining and which normally occurs when viewing minute images. It has a resolution of 640 by 320 which is quite high and will therefore show you objects or fish located a good distance away.
It features a power output of 250Watts. This involves the production of energy via a sonar transmitter. The more output produced the better and more beneficial it is to the user as they will be able to see long distant targets. It helps enhance performance while moving at high speeds.

The high quality 581i Combo which features a dual beam, power output of 250Watts and internal GPS to mention just but a few, is a suitable option for anglers looking to achieve excellent end results.
The main downside of this particular model is that the display is in black and white, although it really shouldn’t deter you. What is important is the power it has, and being able to locate sea life at depths of up to 800ft will be sufficient to most fishermen.
The Humminbird 581i Combo has also received positive reviews from the very vast majority of customers that have purchased this model. An important indicator of potential satisfaction.
Considering some fish finders cost much more than this one, we highly recommend the 581i Combo for any amateur fisherman.
