iGillsWant to record your next diving trip but don’t want to invest money in a new underwater camera? How about waterproofing your iPhone instead? If that’s what you have in mind, the iGills is just what you need. The iGills is a polycarbonate case that turns your iPhone into an underwater video and still camera at depths of up to 40 meters. In addition to keeping the phone safe from water, the case acts as a way to interact with the phone when you’re underwater (you won’t be able to access the touchscreen normally) – it features buttons that can be used with iGills’s own dedicated app.

In addition to being a camera, the app will help you keep track of your depth, time underwater, nitrox levels, temperature of the water you’re submerged in (the case has built-in sensors) and alarms you can program to remind you of your oxygen supply levels. If you’re interested in picking up one of these cases (it works for the iPhone 4, 4S, and 3GS), head over to the iGills website to pre-order one for $329.99.
