Meet the Octospot: a smart action camera that lets you capture 4K video and 12 MP stills underwater. It has magnetic switch buttons and can be operated with gloves. The Octospot Dive Camera is made of anodized aluminum and polycarbonate. It is waterproof to 200m.
This smart cam has a temperature and pressure sensor, so it logs your dive and displays data in your videos. In fact, you will be able to relive dives on your phone. More information is available on Kickstarter.
