GoPros are well-known for being robust. I mean, we’ve seen one fall out of a plane and land intact. This GoPro was keen on going on its own adventure as well, except in the water instead of the air.
According to the video’s poster, the GoPro fell off during the surf (as you get to see) and washed up in a tide pool seven hours later. Seven hours is a long time, so you can take your bets on whether she’s just wrong about it having been seven hours or whether it’s viral marketing or both. In any event, a GoPro could totally do this (if not for quite that long), and it’s neat — though disorienting — to see. And as much as soundtracks to videos like this can be hit or miss, this one’s a hit.
Cool or not, you’d be well-advised to keep your cam out of the ocean and under control; everybody needs to stop dropping these things. [Reddit]
Nice. A bit over long though. Best bit is when the crab tries to bonk it.
I’m doing the surfing with a flipcam HD (in a waterproof housing), it’s all I could get my hands on. Hoping that this doesn’t happen…..
It annoys me made that even the GoPro 3 doesn’t seem to have a proper lanyard point, I mostly use mine just holding it by hand. There’s a guy on ebay selling alloy replacement lens rings that have have a lanyard hole but it would be nice to have something built in.
It least there’s the ‘floaty’ back…
Even if they stay connected, the waterproof cases can pop open. I’ve had 2 become disconnected, held on by a thin lanyard, bounce around for a few mins, then the case pops open. One was saved but waterlogged, the other lost to the depths!
