HydroView

Scuba diving isn't exactly easy, and it's even harder if you're trying to shoot any sort of decent photos or video. So why not let the HydroView ($4,000) do it for you? This underwater vehicle shoots 1080p video and high-quality stills, which it beams back wirelessly to the same iPad that you use to control it via the accelerometer and touchscreen. Other features include on-board LED lights, the ability to reach speeds of five knots going forward and one knot in reverse, and the ability to collect data on water conditions. Just think of it as your very own remote-controlled miniature James Cameron. [Scouted by Chris]
