Features Of Portable Fish Finder

While choosing your fish finder, it’s important that you are well aware of its features. I will tell you some of the amazing features your fish finder should include.

Screen Size And Resolution:

The screen size is an important decisive factor. The screen if the fish finder is preferred to be as big as possible to have a clear view and understanding. As the size of the display unit increases, the rate also goes up. In the case of some portable fish finders, your phone is your display unit. This makes it easy to use. This also gives you your choice of screen size.

When it comes to the resolution, the greater the resolution, the better will be the quality of the display. More number of pixels makes it possible to have a clear image of the underwater world. Devices with low resolution often cause misinterpretation of information and also confusion. In the beginning, fish finders were usually back and white. With the advancement in technology through all these years, they now have coloured screens.

Ease Of Detachment :

When it comes to portable fish finders, they are very easy to install on your boat or kayak and even on your fishing rod.

If you choose a mounting fish finder that can be fixed on your boat, you should look for one with many transducer lines. This will make installing easy for you.

In the case of castable units, they are designed in such a fashion that they can be easily attached or detached from the fishing line. You can lower it according to your requirement and detach it later on.

Wired Or Wireless Connectivity:

In some portable units, you need to wire your battery and transducer to the display unit to work. Such units are mostly cheap. But it also makes it difficult to carry around. You need to make sure you have power input to your unit to energize them.

While in the case of the wireless unit, they do not require any external source of power. This makes it easier to handle. You have to connect them with your phone using wifi to use them.

Weight:

One of the crucial features your fish finder should possess is to be light in weight. Most fish finders are small in size, which makes them easy to use. It is difficult to work if your fish finder is heavy. If you are installing your fish finder on your boat, the weight wouldn’t matter.

Cone Angle:

It is very important to choose the cone angle considering your requirement. Cone angle is nothing but the width of the area under scanning. Wide come angle refers to a higher area under scanning for finding fishes. As the signal transmits deeper into the water, the angle increases, and the sensitivity for detecting decreases. While opting for a transducer cone angle range, you might want to consider if you are fishing in deep or shallow waters. For deep water fishing, I highly recommend you to use a lower come angle. Whereas in shallow fishing, you can go for a wider fishing angle to cover more area. Transducers having dual-beam are also available in the market.

Waterproof:

It is hard to avoid your fish finder unit getting wet during fishing. You may be able to not fully dunk it on water, but water splashes are inevitable. This can cause damage to your fish finder if it is not waterproof. This it is ideal to opt for a fish finder that is waterproof.

Such units generally come with a plastic coating to avoid corrosion. This helps it last a longer period of time.

How Does Fish Finder Work?

Fish finder works on the principle of the SONAR system. It transmits ultrasonic waves into the water, which upon hitting reflects backs. This reflected signal is detected and decoded to find the size, shape, and composition of the object it hit. Accordingly, the signal is sent to the display unit.

Which Benefits More From Portable Fish Finders?
