Yes, you can use a GoPro in a waterproof case to capture your diving adventures. If you use your action mostly for diving, though, you might want to trade that setup in for the Octospot, an action cam that’s custom-built for the job.
Unlike most action cams, it won’t require a separate case to provide the waterproofing. Instead, the darn thing is built to function in depths of up to 656 feet, allowing you to use it in depths where regular action cams would have been rendered inoperable.
The Octospot takes on a tube shape based on diving torches, making it easy enough to carry by hand, while being unobtrusive when mounted on the side of a dive mask. It can capture 4K video at 30 fps, 1080p video at 100 fps, and 720p video at 240 fps, along with 12 megapixel stills, with onboard temperature and pressure sensors, whose readings can be overlaid on top of the videos if you’d appreciate the extra information. Because of the onboard pressure sensor, it’s able to determine your current depth in real time, allowing it to adjust the camera’s white balance to optimize the captured images even at extreme depths.
Features include a 155-degree lens, a 0.5-inch display in the rear that shows vital information in real time, T-rail click mounts all around the camera body for easy integration with accessories, onboard Wi-Fi and Bluetooth, and a battery rated at two hours of use. It comes with two included mounts (one for dive masks, one for everything else), as well as a few other optional accessories. And, yes, we think the dive mask mount might work with snorkeling masks, too.
A Kickstarter campaign is currently running for the Octospot. Pledges to reserve a unit starts at $369.
