What’s in the Box?

Once you unpack the box, you will notice that the fish finder comes with a wireless T-box. This T-box will transmit the data from the finder to your smartphone. What’s more, you get a transducer with the box to search for fish. To plug it, you get a USB 12V adapter. It even comes with screws to attach the transducer to the boat. There is even an armband to keep your phone safe. Great deal for such low price.


Who will be benefitted with this SonarPhone?

This fish finder will be very useful for both newbies and advanced anglers. However, it is not a good option for pro anglers. Beginners and semi-pro users will be highly benefitted with this fish finder. If you don’t have a smartphone, then it is not a good option for you, because it uses the display of your smartphone. Vexilar Sonarphone can be used for ice fishing purposes also. It can work as ice flasher. So if you want a fish finder which is capable of both regular and ice fishing, you will absolutely love Vexilar SonarPhone fishfinder.


How does It connect?

One of the great thing about this fish finder is that it uses wi-fi to connect to your phone. No matter whether you are using Android or iPhone, it can be connected to the phone. As a result, if you have a smartphone, you can save a lot of money by purchasing this fish finder instead of a fish finder with a display.

Once you put the fish finder in the water, it will be on and start connecting with the phone within minutes. The transducer and the wireless T-Box will be connected, and it will be powered by the 12 volt USB connection. The green T-Box will route the data via the Wi-Fi to your smartphone and allow you to start mapping or charting the transducers findings. The data are shown on the display of your smartphone or tablet.

FreshWater vs. Saltwater

Even though this fish finder can be used in both freshwater and saltwater, it is suggested to avoid saltwater. However, if you want to use it in saltwater, you should clean and dry it after using.


Sonarphone Mobile App For Smartphone and TabletsSonarPhone by Vexilar Android APp


If you want to use this fish finder, you need to install a mobile app on your phone or tablet. This app will help you to turn your phone into a sonar system. Note that cell phone coverage is not needed as the connectivity with the device is done by wi-fi. The SonarPhone transmitter will create its own hotspots which can be used by multiple persons at a time and can be protected via the password.

The display is in color mode and has a good UI in it. You can change the language in 17 different languages including the major ones like English, French, Polish, Portuguese, etc. The app is easy to install and use. You can find the app on AppStore and Playstore.

You can use the display on your phone to change the settings for the transducer. It depends on the weather or maybe location. If you want narrow or precise search, you can alter the cone of the transducer by 40 degrees. For wider search, you can make necessary changes too. At the top of the screen, you will be able to access the gain.


Ice Fishing

It can be used for ice fishing also. However, the performance on ice fishing may not be very satisfactory, but it surely works quite good. If you are serious into ice fishing, you should check this Humminbird ICE-45 Three Color Flasher Review.

However, many people already informed that ice fishing with this Vexilar SonarPhone is working great. I have seen many anglers doing great with this device in ice fishing. The ice flasher option can be very useful for ice fishing.

If you are extremely serious about ice flasher, then check the Humminbird ICE-45 Three Color Flasher for serious ice fishing. That’s my opinion.


Navionics App

You might be wondering about the navionics feature. This additional app can be purchased separately to turn your mobile device into the GPS system. You can use it later on for other purposes also. The app is not expensive rather very useful if used properly. The app is fully functional and works fine with this fish finder. You can navigate smoothly and follow the map for better navigation.
