If you’re an avid fisher, you need the Deeper START smart fish finder to help you see clearly underwater. This fishing gadget features a depth and range of 165 feet each, allowing you to use it in vast open waters. Simply place the smart fish finder in water, and it’ll share helpful information so you can locate fish. And it’ll send live data to the app for you to interpret. This data includes the size of fish, depth information, and vegetation and weed location. But the most impressive feature of this gadget is the Fish Alarm. The device will send a sound notification to your phone when it’s picked up movement underwater. This audio feature means that you don’t have to take your eyes away from the water to look at your phone.
