Sharkbanz has spent over a decade building the world's leading magnetic shark deterrent technology, backed by peer-reviewed research, government field studies, and real-world validation from over 200,000 users worldwide.

As our technology has grown, so has the spread of misinformation — from viral videos with flawed methodologies, to studies designed outside our product's working parameters, to counterfeit products on Amazon that create a false sense of security. This information sets the record straight — providing everyone a clear and honest resource on our products and technology.

The magnetic field created by Sharkbanz follows the inverse cube law — field strength drops exponentially with distance. At 10 feet, it's undetectable by even the most sensitive lab equipment.

Sharks detect electric fields through their ampullae of Lorenzini, their highly developed sensory organs used to navigate and hunt especially during the final, short-range stages of prey identification. A shark at distance uses vision, smell, and lateral line detection — not electroreception.

The short-range electric field created by Sharkbanz technology is designed to overwhelm a shark's electric sense. Marine biologists compare this deterrent effect to a bright light flash in your eyes within a dark room. This unpleasant sensation does not harm you (or a shark) but it causes a person (or a shark in this case) to turn away.

For investigative encounters — yes, the science supports it. Peer-reviewed research confirms magnetic fields elicit avoidance in White Sharks (C. Carcharias). Dozens of customer accounts describe successful deterrence of investigative Great Whites in Australia, California, South Africa, and Cape Cod. However, while avoidance behavior is possible through the use of personal deterrents, it is never guaranteed - especially with great whites.

For high-speed ambush attacks — no product can. Great whites are the only shark species that hunts via ambush, attacking from distance at extreme speed. No deterrent device — magnetic, electric, or otherwise — can reliably stop this behavior.

We believe honesty about limitations builds more trust than false guarantees. If a company claims their product prevents all great white attacks, that should raise a red flag.
