This echo-sounder is basically a round ball you put in the water and connect your smartphone or another device via a special app. The range (or depth) is up to 40 m (130 ft). The device uses 2 beams: the first one has a frequency of 290 kHz and the second one 90 kHz. One beam is used for mapping the bottom while the another one is used for scanning the area around. This technical capability is very beneficial for searching the fish.
All the information is displayed on the screen of your smartphone (or tablet) via the special application called 'Deeper'. Apart from the underwater data, it also shows the temperature of water, shows a lunar fishing calendar, includes social network integration, etc. The image quality depends on the screen of your device.

What Is a Fishfinder?
Modern technologies greatly facilitate the process of fishing. Recently, a lot of high-tech appliances have appeared on the fishing equipment market. Thanks to that, you can catch fish effectively in almost any conditions.
A fishfinder is a very handy appliance for any fisherman. It helps you literally look through the depth of water and detect the fish, so you can save time and find the best place for fishing. And if you think a depth finder is just a radar you are mistaken - it allows to scan the relief of the bottom, so you know what is underwater - it is very important for divers.

What Features to Compare
A choice of a good fish finder is a guarantee of a successful fishing. There are several important features you need to consider when you choose a depth finder. A common person will get nothing from reading too difficult technical terms, so we have decided to make it all much simpler so that an average person can make a choice.
The first thing you need to consider is the Detection Range which means how deep underwater a fishfinder can scan. It is usually measured in meters or feet. Also, as an additional information, we give you a more profound information such as scanning angles, the power of a radar, a number of bands, and so on.
Having chosen a detection range, you need to realize how exactly the information is displayed and we have called this feature Data Mapping. Some fishfinders are autonomous and have TFT screens where all the data are shown, whereas others work via a special app you install on your smartphone or any other portable device. The graphics is different - some depth finders make a really detailed picture.
Finally, you need to know when and where you can use a fishfinder. Some of them are better for boat fishing while others are perfect for fishing from on the shore. That is why we give you a detailed information about the Usability. The best fishfinder sonars can be used in fresh water and in salt water.
