The Lucky Smart WiFi Sonar is a compact, WiFi-operated fish finder specifically designed for modern anglers. The device uses sonar technology to examine the underwater area and transmits the data in real-time to your smartphone or tablet. This means no separate display is needed – your phone becomes the fish finder display.

The transmitter placed in the water sends ultrasonic signals towards the bottom, and based on the reflected signals, it displays the position of fish, water depth, water temperature, and structure of the bottom. This is a great help in finding the right fishing spot, especially during bait boat or bank fishing.

The device is small, easily portable, and can be used as a castable sonar, for kayak fishing, or mounted on a bait boat. Thanks to the WiFi connection, it can transmit data to the mobile application from a distance of up to 70 meters.
