Meet iBubble: an autonomous underwater vehicle that lets you capture beautiful footage underwater. It does not make a lot of noise and avoids obstacles. The device returns to the diver when out of battery. It automatically goes to the surface in case of an emergency. With its image stabilization system, you will be able to capture smooth underwater footage.
iBubble has 1-hour battery life. It comes with a bracelet that lets you call it back. A manual mode is also available. This cool underwater drone is available for as low as $1299, but you have to be an early supporter.
