Because why on earth wouldn’t you use a GoPro to swim with Sharks?

So, this is a new one. Today, at 17:00 GMT, GoPro will be livestreaming athletes Jeb Corliss and Roberta Mancino as they swim with great hammerhead sharks, without the safety of a protection cage.

Shooting with the GoPro Hero 4 Black and streaming via Periscope, the firm will broadcast its first ever underwater live stream off the Bahamian island of Bimini.

In an interview with GoPro, Jeb and Roberta said they want to get viewers closer to sharks than ever before. Jeb said that he and Roberta “hope to have anywhere from three to seven sharks” in the water with them by the time they go live.

Great hammerheads are, by all accounts, quite enormous, known to grow to up to 20 feet in length. They can apparently be very “energetic” according to Jeb, and will make contact with divers if they feel like it.

Fear not though, for he and Roberta have a plan. If the sharks do get “excited”, he says, the pair of them will “get back to back and defend each other as [the sharks] come in for the bait.” So, you know, that’s fine then.

In order to get the footage, the pair are going to be using a Wi-Fi extension cable and four of the GoPro Hero 4 Black Edition cameras, each of which will be capturing stills at different frame rates.

He’s also got a pole, he says, in case he needs to defend himself, and for the hell of it he’s going to stick a GoPro on the end of that as well. The live feed will be coming from a GoPro mounted to the side of his Guardian Full Face underwater communications mask.

Tune into GoPro’s Periscope channel at 17:00 to see it all happen. We’ll be watching, albeit through our fingers.
