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. We enlisted the services of renowned shark experts, chemist Dr. Eric Stroud and marine biologist Dr. Patrick Rice. The two scientists founded Shark Defense almost 15 years ago, and are now the leading researchers in shark repellent technology. 

Sharkbanz use special patented magnetic technology to deter sharks from attacking people. 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. In this environment, sharks rely heavily on their electro-receptors instead of their eyes to “see” what’s around them. They possess the most sensitive electro-magnetic sense of all known animals, and use it to judge distance, shape, and even the heart rate of other animals near them. Most of the time, sharks get it right and leave people alone. Occasionally, they don't. Sometimes when relying on their electro-receptors, a curious shark may bite a person in order to figure out what he or she is. 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. The experience for the shark is, “like a person suddenly shining a very bright light in your eyes in a dark room, and it's not pleasant”, according to Dr. Stroud.  Once a shark comes near the band, it frequently leaves the area and does not return. To see video of some of our tests, click here.

Dr. Rice says that the effect of Sharkbanz is amplified if many people in a group of swimmers or surfers are wearing them. As more people choose to wear Sharkbanz, the more everyone’s risk is reduced. An approaching shark will be deterred sooner, keeping you, your friends, and sharks safe to enjoy another carefree day in the ocean. 

It is important for us to be honest about what Sharkbanz technology can and can not do. Sharkbanz will reduce risk of shark interactions but there is no 100% guarantee that interactions will not take place. This technology has been tested extensively on over ten of the most common predatory shark species (http://bit.ly/ZyJ47I  not effective on Great Hammerhead) such as Bull and Blacktip, which are responsible for the majority of "hit and run" attacks, and Sharkbanz are an excellent defense against these types of attacks. Great Whites are unique in that they are the only shark that acts as an ambush predator, attacking from a long distance at high speed. There is no effective way to prevent this type of ambush attack. However, Great Whites rely heavily on their electromagnetic sense when swimming in open water, and Sharkbanz could effectively deter an investigating Great White.

Sharkbanz are not designed to prevent sharks from eating visible bait. They have a hierarchy of senses and can override the electrical sense in the event that visible bait is present. Again, Sharkbanz are meant to deter curious sharks from biting a person while in investigative mode, not prevent them from eating bloody fish bait. 


Sharkbanz use no chemicals, batteries, or electricity to deter sharks, ensuring simplicity in use, storage, and durability. Just strap it on when you arrive at the beach, and let your fears fade away.

Our goal was to make a product that posed no risk to the wearer, protecting people and sharks. Great care was taken so that no sharks were harmed in the testing of our product, and we follow all procedures and guidelines of the IACUC.  At Mano, we like sharks, and if they could talk, we’d want them to say, “people are friends, not food!” Sound familiar? The safer we feel, the more likely we are to support these vital members of our ocean ecosystems. 

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.


Unlike other shark deterrent products, Sharkbanz don’t repel people because of their looks. We currently offer three colors in a compact, stylish design inspired by the most popular fitness bands.

Our design wizards came up with a secure clasp system that will allow Sharkbanz to fit the wrist or ankle of almost all men, women and children. Share it with the family or loan it to a friend, just make sure they give it back! You definitely don’t want to be the one without it.

Sharkbanz are not designed for children under 5, and young kids should always be supervised in the water and while using Sharkbanz. They contain powerful magnets, which can cause damage to electronic devices and computerized equipment. Always consult a doctor before use if you have any metal under your skin, such as pacemakers and hearing aids.
