Sharkbanz Could Save You From a Shark Attack

I’m sure Mick Fanning wishes he’d been wearing Sharkbanz while surfing at Jeffrey’s Bay the day Mr. Whitey came calling. This new device throws out a magnetic field that repels sharks. At least Bull Sharks as this video shows. Not sure if it would stop the freight train of a Great White but it can’t hurt, right? I think the real key for this would be integrating into a surf leash ankle strap or building into the foam of the board itself…hmmmmmmm.


The Bull shark is widely considered the most dangerous shark to humans because of its aggressive nature and nearshore habitat. The magnetic technology inside Sharkbanz was first tested on Bull sharks several years ago, and we’re excited to bring you the next episode of our Tech in Action series.

Bait chunks were placed inside Bernie’s foot and he was sent out to fend off 6 large, hungry Bull sharks. After about a half hour with no bites and numerous repellent reactions, the Sharkbanz was removed and Bernie was returned to the water. Within 2 minutes, his foot was attacked.

Sharkbanz are an easy way to add peace of mind to the everyday ocean swim, surf, or snorkel, but make no mistake: the science is real. To create this breakthrough protection from sharks, we partnered with the leading shark repellent scientists at SharkDefense. They’ve put this patented magnetic technology to the test for over 10 years against the predatory shark species most responsible for attacks on people, including Bull Sharks, Blacktips and Tiger Sharks. Most shark attacks occur in murky, shallow waters off the coast where there are a high number of swimmers and sharks sharing the same space. These unprovoked “hit and run” attacks are the most common type, and Sharkbanz are an excellent defense against them. As the shark approaches a person wearing Sharkbanz, magnetic waves coming from the band disrupt its electro-receptors, and it quickly turns away. For the shark, the sensation is similar to someone shining a very bright flashlight in your eyes in a dark room, and while this deters the shark, it does not harm it. Stingrays are also repelled by Sharkbanz, and the technology does not affect other marine life.

Sharkbanz use no chemicals, batteries, or electricity to deter sharks, ensuring simplicity in use, storage, and durability.

While there is no 100% guarantee against an encounter, Dr Rice says that by wearing Sharkbanz, the risk is significantly reduced. There’s a fine line between bravery and stupidity, so don’t cross it and provoke a shark by attempting to test this technology yourself. They are wild animals and don’t take kindly to people with bad manners. Respect the animals and they will respect you.
