When we enter the ocean we must consider and respect the shark, because we are in their natural environment. Nonetheless, finding yourself in the company of a hungry or curious shark is not a good feeling, seeing as we have no natural defense.

We do have brains however and research has shown that the eyes, gills and electrical receptors around a shark's snout are their most sensitive parts. Therefore we've designed and developed The Biteback to help fend and fight off these apex predators and increase your odds of survival in an attack.

Who's it for?


...I like that it can be accessed quickly in an emergency. When I was bitten by a Grey Reef shark at Enewetak Atoll, it would have definitely come in handy. I was bitten on my left hand and my partner was bitten on his right arm. Even though he had a bang stick mounted on his backpack, there was no way for me to remove and activate it, since it would have required two hands. I can see how your product would be a lot easier to use, plus would not be nearly as dangerous to use. It's nice to know it won't kill the shark either!

I like the Biteback's design. Its simple.  Next time, I'm biting back!
