Aguadrone, a crowdfunding project on Kickstarter by Daniel Marion, manages to combine the worlds of fly fishing and remote control aircraft, creating a waterproof quadcopter with some niche potential.Like the Splashdrone, the waterproof Aguadrone floats and carries a camera for underwater picture-taking. But photography is just the baseline here. What makes the Aguadrone a unique vehicle are the other pods that it can carry. There’s a sonar pod, which sends out a 300-foot Wi-Fi signal when in the water, sending its scans of the water below to a cell phone or tablet without the need for a cell tower. This means the pilot can look to see just how deep a river is, and maybe even find fish under the surface.
