Feel naked without your iPad? Never fear: It can come along on your next dive with a new housing by iDive, which inflates a thin, flexible bubble over your iPad screen. Brave inventor Michael Berumen, a marine sciences professor, first tested the idea with a Ziploc in his bathtub. With the help of Watershot Inc., he added a sturdy frame that stands up to extreme pressure, and a system to bleed air on ascents. Plugged into a CO2 cartridge, the device can tag along with advanced divers to 130 feet.

Even in the shallows, the housing is a game-changer: ReefID is working on an app that draws on facial-recognition technology, so any diver or snorkeler can help scientists catalog marine life.

But don’t plan on checking Facebook on your safety stop just yet — there are (thankfully) some places cell and Wi-Fi signals still can’t reach. idivehousing.com
