Shopping guide

Capacity and measurement system
By definition, a sonar is a product that sends sound waves and, depending on the way they bounce off objects, is able to know what kind of objects have been found and how far, or in this case, at what depth they find each other. Therefore, the sonar detection system is always based on this principle.

However, there are differences in the way this system works, depending on the audio frequencies used. For example, the greater the range of audio used, the farther the sonar can go and the more depth it will be able to work.

At the time of choosing it is advisable to bet on models that reach the level of depth that we need. In this aspect, some products incorporate long cables for the transducer that increase the range. And in some, we even have independent sensors that allow us to go even further in our searches.

Data presentation
Once the sound signal data has been processed, these are normally presented on the screen, duly interpreted. This is another key element, since sometimes the difference in how much a fishing sonar costs depends on the type of screen. And seeing the quality offered by some, it is worth paying.

Within the available models we can find LCD screens, similar to a conventional clock, where the results are shown in overprint. Better in quality are the LED screens that, despite their tight size, offer more image quality. In this section, the better the resolution and the image size, the better it will be to see everything clear.

For that reason, perhaps the most outstanding models in this aspect are those that use our mobile as a screen. Through a wireless connection, the data is sent to the terminal where we can see them in large size and high color quality. This makes it easier to see them, manage them or even send them where necessary.

Power and operation
As last important aspects, it is necessary to take a look at the ease of use or operation of the product, as well as its power supply. A sonar that is difficult to use or that does not have a battery may not be a useful product.

On the side of the operation it is advisable to bet on models with bototeras that allow us to move easily through the different options of the team. If, in addition, we can zoom or scroll through the different screen elements easily, much better. In the case of those based on mobile apps, it will be these that must cover this need.

As for the battery, a computer that does not offer you at least 5 or 6 hours of useful life should not be considered, at least in general terms. If it is true that if it is a battery model, there are no problems, although you will have to carry them, of course. In the case of battery models, it is also advisable to have a backup battery when the power supply of the installed device fails.
