Portable and wireless, the ReelSonar fishfinder system consists of a bobber and a complementary mobile application for smartphones and tablets. The bobber connects to a device via Bluetooth Low Energy (BLE) with a range of up to 150 feet – no cables required!

The bobber uses sonar and patented technology to detect the presence of fish, map the waterbed and measure water conditions. You attach it to the end of your fishing-line; cast it to your desired location. The bobber immediately turns on and sends information such as the waterbed map and temperature to your device.

The ReelSonar App is compatible with Android 2.2 and iOS5.0 and higher. The app will be available on the App Store and Google Play in April 2013. The ReelSonar bobbers will be available July 2013.

ReelSonar is the idea of two tech geeks in Seattle that just so happen to be brothers. They love to fish. They love smartphones. The two have a background in medical ultrasound technology. For the past year, they have been working with a team spending countless hours bouncing ideas off of professional and amateur anglers, researching, designing and testing ReelSonar technology. The ReelSonar team consists of hardware Engineers, RF Engineers, Embedded Software Engineers, Mechanical Engineers, App Designers and Anglers.
