Smartphone fish finder

    The fish finder sonar orb will pair with a smart phone to scan beneath the water, letting you know the best place to sink a hook.
    The fish finder will be able to withstand depths up to 120 feet and have a Bluetooth range of 150 feet. Once tied to a line and submerged, the waterproof orb will use sonar waves to gather information about temperature, depth, and the locations of the fish. The information will then be sent to the phone in the form of a depth chart image, with approximate fishy areas clearly marked.
