Wireless Castable Fish Finder – Smartphone Sonar

Explore the water before your next cast

Turn a compatible smartphone into a portable sonar display with this rechargeable wireless fish finder. The compact floating sensor sends underwater readings to its companion app, helping you assess depth, bottom contours and potential fish activity without a separate handheld screen.

A clearer picture of your fishing spot

• Phone-based viewing: use the companion app on a compatible iOS or Android device to view sonar information.
• Castable floating sensor: tether the unit using its attachment points and keep the underwater transducer in contact with the water.
• Wide sonar coverage: a specified 90° beam helps survey the area beneath the sensor.
• Rechargeable design: recharge with the supplied cable between sessions.
• Compact kit: carry the sensor in your fishing bag and use your own phone as the display.

Before you head out

A compatible smartphone and the companion app are required; this sensor has no built-in screen. Follow the supplied guide for app installation, pairing and charging, and check compatibility with your phone. Wireless distance and sonar readings depend on water, positioning, interference and weather. Fish indications are sonar estimates, not a guarantee of a catch. This is a fishing aid, not a navigation or safety instrument. Secure the sensor with suitable tackle and close the charging cover before use.
