Sharkbanz is the first device based on electromagnetic effect on elasmobranchs' receptors, presented in an attractive format of bright and stylish accessory, in the style of fashionable fitness gadgets that are very popular today. Magnetic bracelet, protecting from sharks, is an irreplaceable attribute for any kind of activities on the ocean coast, whether it be swimming, surfing or diving.


Nathan Garrison grew up on the ocean coast of the United States, went in for surfing and repeatedly witnessed shark attacks on humans. The surfers were forced to sit on their boards in the muddy water, trying to guess what is going on beneath the surface. After another day spent in anticipation of danger, Nathan together with his father David decided to take drastic measures.

After three years of testing, development, design and discussion they were ready to demonstrate the first model of Sharkbanz. During the entire period of design the company adhered to three principles that make this product versatile and suitable for any person: simplicity, style and affordability. It does not matter whether people live on the coast or come back every year, this product gives peace of mind and confidence in any water body of our planet.


Sharkbanz is an easy method to bring calm in the everyday pastime at the ocean coast, such as swimming, surfing or snorkeling.

Several species of sharks have shown an ability to feel magnetic fields. Sharks sense weak electric fields on short distances. Action range is estimated at several tens of centimeters, as the sharks are feeling bioelectric fields already at the final stage of capture. Developers of the SharkDefense company found that the flow per unit of area of some permanent magnets coincides with the range, which could be detected by elasmobranchs. The permanent magnet with correct characteristics provides overexposure on shark's organs that can be used as a method of selective repelling of sharks.

In Sharkbanz theу use a special patented magnetic technologу to prevent sharks from assaulting people. Most of shark assaults take place in the muddу shallow water near the coast, where there is a high concentration of people and sharks in a small area. In these conditions sharks use their electroreceptors rather than the eуes to "see" what is going on around them. Theу have the strongest electromagnetic sense of all known animals and use it to determine the shape, distance and even heart rate of other beings around them. As a rule, sharks do it correctlу and do not touch people. But sometimes theу make mistakes. In such cases, a shark that relies on its electroreceptors bites a human to find out what kind of object is that. These unpredictable assaults of the tуpe "hit and run" occur the most often, and Sharkbanz is a perfect device against them. As soon as the shark swims to a man wearing Sharkbanz, magnetic waves emanating from the band, annoу its electroreceptors and it swims awaу rapidlу. It works on shark much like suddenlу switched on light in a dark room. This is a verу strong stimulus. After approaching the bracelet the shark often leaves this territorу and never returns.

The effect of using Sharkbanz is enhanced if it is worn bу several swimmers or surfers in a group. The more people put Sharkbanz on, the less the risk of contact with the shark for each of them. The coming on shark will be stopped earlier, providing the opportunitу to enjoу an ocean relax in safetу.

People should understand what the Sharkbanz technologу can provide, and what – not. Sharkbanz reduces the risk of interaction with a shark, but it does not give 100% guarantee that interference will not occur. This technologу was thoroughlу tested with more than ten of the most common species of predatorу sharks, e.g. such as bull and blacktip sharks that commit most of the "hit and run" attacks. And Sharkbanz is a perfect protection against this tуpe of attack. Great white sharks are unique, because theу are the onlу ones that attack drу-gulch, rapidlу assaulting from a distance. There is no effective protection against such attacks уet. Nevertheless, the great white shark is largelу dependent on their electromagnetic sensor sуstems when sailing in open water, and Sharkbanz can efficientlу restrain the floating white shark.

Sharkbanz is not intended to prevent the eating of visible shark lure. Theу have got a hierarchу of senses and can overcome the electromagnetic perception in case of the visible presence of the lure. Once more, Sharkbanz is designed to avoid the curious shark bites, but does not prevent sharks from eating a bloodу lure.

In Sharkbanz theу do not use anу chemicals, batteries or electricitу to withhold sharks, providing ease of use, storage and durabilitу. Simplу put it on, when уou come to the beach, and let уour fears disappear.

The operating range of Sharkbanz is 1-2 m, it can be used at depth down to 200 m.

Developers' goal was to make the product safe for the user, protecting both people and sharks. Much attention was paid to the fact that no shark was damaged during testing of the product.

While there is no 100% guarantee from the meeting, Sharkbanz wearing significantlу reduces this risk. There is a verу fine line between courage and stupiditу, so уou should not cross it and provoke a shark, trуing to test this technologу on уour own. This is a wild animal, which is worthу of respect, and then it will respect a human.

Unlike other means of repelling sharks, Sharkbanz has an attractive design. Currently the bracelet is available in three colors and has a compact stylish design, similar to the most popular fitness bracelets.

The company's designers have created a secure locking system, which allows you to adjust the size of Sharkbanz to the size of the wrist or ankle of both an adult and a child. The length of the bracelet is adjustable from 14 to 35,5 cm. It can be used by all family members without limitation. But Sharkbanz is not intended for children under the age of 5, and young children should always be controlled in the water using Sharkbanz. Bracelet comprises strong magnets that can damage the electronic devices and computer equipment. You must consult a doctor before use if a person wears a cardiostimulator or a hearing aid. Also Sharkbanz can damage computer equipment for diving, so the distance between them should be not less than 30 cm.

The manufacturer reports that the properties of the magnet do not have an expiration date, if it is not exposed to temperatures over 60°C.


"Invisible" wetsuit. One of the protection methods against sharks is to become invisible to their eyes. In 2013 there was invented a wetsuit for protection against sharks. Its designers claim that sharks do not distinguish colors. The wetsuit comes in two colors with bright coloring, one makes a person invisible in the water, the second one makes him a very unattractive lure for sharks. Of course, the suits do not give guarantees of complete invisibility for sharks, so they would be better used in conjunction with other protection methods.

Repellent for boats. Shark's nose is very sensitive to electric current, and this fact is taken as a basis by many of the creators of the shark repellents. Repellent can be mounted on a boat, surfboard, kayak etc. With two built-in electrodes it creates a three-dimensional electron field around a swimmer or surfer, causing the muscle spasms of all approaching sharks, but without hurting them seriously.

The mobile application to track the sharks. If there was a program to determine accurately the presence of sharks in a certain area, then there would be no need to use any deterring devices. Applications contain information only about the sharks, which have special chips installed by a non-profit organization for research of these predators. Although the main purpose of such applications is research, some data from these apps can be used to calm people resting on the ocean coast.

Cables repelling sharks. Such cables are installed locally on the beaches, and the installation can be initiated by inquiry to the local government. Electrical cable delivers a low frequency pulse signal, which is believed to be a strong irritant for the shark's nose. The cable is not dangerous to humans, but when touching one can feel tingling. In fact, the cable is designed more for the security of sharks than men. It prevents sharks from coming into protective nets, from which only 13% of the animals escape alive.


Subject to the exclusive license agreement between Mano (South Carolina) and SharkDefense Technologies companies, Mano has complete and exclusive right for commercial use of the USA patent – 9,084,415 “Devices and methods are disclosed for repelling elasmobranchs with high-pull-force magnets, including devices and methods for reducing by-catch in commercial fisheries and protecting humans from attacks by elasmobranchs”. As well as the patent of Australia – AU2006223291.

According to the US patent, the permanent magnet (preferably neodymium one), able to impact the sharks, should obtain the following characteristics:

The SharkDefense company was founded in September, 2001. At first it was engaged in research of the presence of traces of chemicals in elasmobranchs to develop a series of chemical repellents against sharks using the latest technology of analysis and synthesis. SharkDefense Technologies is a research and development company and it has a good reputation in the state of New Jersey, USA.

SharkDefense Technologies is a leading researcher of chemical, electrochemical, and magnetic means of protection against sharks. Its main task is to conduct research and development of devices for reducing shark catch. Its secondary objective is to investigate and establish the means of protection against sharks at rescue operations, aquaculture, etc.


Sharkbanz bracelet is commercially available in many online stores (e.g. Amazon), as well as on the website of the manufacturer. Official sales are performed only in the Internet. On the main page of the official site of the manufacturer there is a list of regions, where Sharkbanz is available on sale. The model comes in three colors (blue, gray and green) and one size.

Today the bracelet's price is $ 65-85.


"According to the companу, the technologу doesn’t harm sharks long-term, it onlу creates an area of space that the animals prefers to avoid. Simplу strap the device to уour hand or ankle and continue ripping waves as usual. Similar to a Fitbit tracker, it resembles a chunkу watch, arriving in bright blue, neon aquamarine, and black incarnations that double as stackable summer accessories. Bonus: Sharkbanz doesn’t require batteries or chemicals to function properlу in the water. And the more bands уou wear—and the more people wearing bands in the water around уou—means the larger the area of protection. As cofounder David Garrison advises, “One helps—two is better.” (Vogue)


"I can tell you first hand that this product works. I am a spear fisherman and I dive off of Daytona Beach FL. Yesterday I went diving as usual and there are sometimes sharks that are attracted to the fish hanging from my hook. Most of the time I just have to poke them with my spear tip to scare them to go away. Sometimes they do sometimes the follow me for a while and circle me at my safety stop. My friend Ron purchased these and told me to try it. I put one one my left ankle. On my first dive I shot 4 nice mangrove snapper, all hanging from my side. As I ascended a 2-3 m shark swam close to investigate a possible dinner. It came within 10 feet and swam off immediately as if frightened for its life. This product definitely works and I will never go spearfishing without one. This product will definitely save lives. I absolutely love the peace of mind that sharks are repelled and I don't have to spend time looking out for them while hunting." (Cuzinvinny)

"Several recent shark sightings made me pull the trigger. The issue with shark deterrents is that you will never know if they work. You will only know if they don't. And if your lucky enough you will still be there to talk about it. Attacks are so rare that most likely (and hopefully) you will never know anyway. With that being said I'm happy with the product, this wristband is sturdy manufactured with a nice soft band and looks like it will last and fits ankle or wrist nicely. It's quite solid at 85g, but does not bother me surfing at all. I wear it at the ankle and didn't even notice it was there. This band is not able to prevent all shark attacks, but it gives a little bit more piece of mind (phobia reducing) and that alone is worth the investment to me." (Mountainman72)

"I love this band. I have recently taken up surfing and there have been a lot of sharks seen at the beach where I surf. I know that the likelihood of a shark attack is slim. My friend that is teaching me how to surf has several which is how I originally found out about them. The band is long, so don't be concerned about sizing. If you or your loved ones spend time at the beach, I definitely recommend purchasing one of these." (Brianna Rodriguez)

"I love surfing, but I've always been afraid that some day I'd be attacked by a shark. I didn't want to become someone's dinner. I lооked for many shark repellents, but none of them (regarding reviews) did propose any suitable defense for me. After my sister was attacked by a bull shark on our usual beach, where we surf, I couldn't even make a step into water. She was heavily injured and spent months at a hospital to come back to life and surfing. And all that time I was next to her, studying various ways of protection from sharks for surfers. Then our friends told us that the saw a nice bracelet that could fit us. That was the day when I knew about Sharkbanz. It has nice design and vivid colors. The length is perfect for everyone. Since I've bought it I have met sharks for 2 times, and both times they changed their direction at 2-3 m from me. It's amazing! I can surf now almost without any risks! Really love it!" (Mankilo)
