Meet the AguaDrone: a waterproof drone with a sonar fish finder, bait drop, line casting pod, and camera that lets you fish like a pro and capture all the action. The drone can land or takeoff from fresh and saltwater. It has plug & play components and has handy features such as Return to Home, Fail Safe Return, and Follow Me.
There are a bunch of useful pods available for it, including an Open Source Pod to attach your own gear. This waterproof drone is expected to ship early next year.
