The world's first active shark deterrent band. Proven shark deterrent technology.

Designed for beachgoers, ocean athletes, and marine professionals, Sharkbanz use patented magnetic technology developed by marine biologists to deter predatory shark species.

*Sharkbanz Technology has been verified by an independent third-party analysis group at the prestigious School of Coastal Environment Department of Marine Science at Coastal Carolina University (USA). Furthermore, our shark deterrent technology was proven effective at reducing shark depredation in recreational fishing by the WA Government (DPIRD) in a year-long 2021 study.

Who should wear Sharkbanz?
Sharkbanz are for anyone who spends time in the ocean, from seasoned watermen to the casual beachgoer. Our patented technology offers convenient protection for man, woman and child in a variety of activities. They are designed to prevent the most common hit and run attacks from the majority of shark species found in shallow coastal waters around the world.

How many Sharkbanz do I need to wear?
Worn on your wrist or ankle, one Sharkbanz unit will help reduce the risk. However, wearing two Sharkbanz (one on your ankle; another on your opposite wrist) will increase the overall deterrent field size and thus provide greater coverage – similar to how other safety devices work.

If only wearing one, we suggest wearing Sharkbanz on your ankle, as the majority of shark bites occur on the ankle and leg areas.

What’s the range of Sharkbanz?
The field is about 1-2 meters (about 3-6 ft). The unpleasant sensation becomes intense for the shark at about 1 meter, becoming exponentially greater each inch closer.

Do Sharkbanz affect other ocean animals?
Sharkbanz technology has also been known to deter stingrays, but we do not guarantee deterrent results for those wishing to use Sharkbanz as a means to deter stingrays. Sharkbanz do not attract Sharks, nor are they known to be detectable or harm any other ocean creatures such as dolphins, sea turtles, or other fish species.

Do I need to be moving to generate the magnetic field?
The electromagnetic field is increased by your movement, but movement is not necessary. The simple rhythmic current of the ocean moving you around is enough. Sharkbanz does not need to be submerged in water to deter sharks so keep us in mind next time you take out that Ocean SUP or Kayak.

Will Sharkbanz affect my medical devices such as heart monitor, metal plates, screw, etc?
If you have metal or medical devices under the skin, always consult with your doctor before purchasing and using Sharkbanz.

Will Sharkbanz affect my dive computer, dive compass, or other scuba electronic systems?
Special care should be taken with Sharkbanz and dive computers with compasses. The two can be used together successfully by ensuring the Sharkbanz is at least 24 inches (60 cm) away from the dive computer. By wearing Sharkbanz on the opposite ankle from the wrist with the dive computer, you can ensure it remains at least 24 inches (60 cm) away.

Placing your Sharkbanz within 24 inches (60 cm) of the compass will cause the compass to display an inaccurate reading. Dive computers without a compass feature will likely not experience mechanical problems within close proximity of Sharkbanz.

Avoid direct contact with any sensitive electronics (camera memory cards, hard drives, etc.) and Sharkbanz, especially for prolonged periods of time.

Will Sharkbanz attract sharks?
Sharkbanz emit a magnetic field that quickly drops off, so sharks cannot sense it from far away. Once sharks enter this magnetic field range, they can be deterred, as Sharkbanz has shown to over-stimulate their electroreception. For added peace of mind, please know that based on the laws of magnetics, this magnetic field created by Sharkbanz drops off at the inverse cube of the distance from the source, meaning at a distance of 10 feet and beyond, the field is not detectable by even the most sensitive laboratory equipment.

Has Sharkbanz Technology been tested on all shark species?
This technology has been tested on most common predatory sharks, including Bull, Blacktip, Oceanic Whitetip, small Tiger, Nurse, Lemon, Caribbean Reef, and Bonnethead. For more information on species tested, please review our full Research page and its links.

*Note from our scientistic partners: Official research tests showed that large magnets deterred Nurse sharks (please see research page for more info), but Sharkbanz will not elicit much of a reaction. Nurse sharks are bottom feeders and use their electrical sense much less than most predatory species, instead relying on their keen senses of sight, smell and barbels. They will bite if severely provoked, but are otherwise docile. Do not attempt to “test” Sharkbanz when diving with nurse sharks, as you may provoke the animal.

Do Sharkbanz prevent Great White Shark 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 electroreception when swimming in open water, and Sharkbanz could effectively deter an investigating Great White.

Much like other safety devices, such as a bike lights, Sharkbanz reduce the risk -- they do not eliminate the risk altogether. That said, customers in Australia and California have used our products to deter investigative Great Whites. You can read these testimonials on our Reviews page.

By purchasing Sharkbanz, buyer acknowledges that Sharkbanz are a deterrent to shark interactions and that there is NO GUARANTEE of no shark interactions. We liken Sharkbanz to other safety devices, such as bike helmets and seat belts. They’re intended to reduce the risk of harm, but they cannot protect someone fully, all the time. Instead, they add protection when previously there was none.

Are there shark species which are not deterred by electromagnetic fields like those emitted by Sharkbanz?
Benthic-based sharks such as wobbegongs (family Orectolobidae) and port Jackson sharks (Heterodontus portusjacksoni) are not deterred by Sharkbanz or electrical shark deterrents, even if placed directly on the animal. Benthic sharks have evolved differently than other predatory shark species like bull sharks and do not respond in the same way to these fields. Benthic species are a minor threat to divers/swimmers, although the wobbegong has been shown to ambush attack swimmers/surfers/divers when unprovoked. Most wobbegong incidents have taken place in NSW, Australia. All cases of wobbegong attacks have resulted in minor injuries with no fatalities.

What is the depth rating of Sharkbanz?
Sharkbanz and Sharkbanz 2 do not have any electrical or pressurized components, and Sharkbanz 2 are waterproof tested up to 100M.

Will Sharkbanz affect my open water swim / triathlon race monitor or timing chip?

Sharkbanz has been officially approved for use in major competitive swim races such as Rottnest Channel Swim and Port to Pub (Australia). Our technology is not known to interfere with timing chips nor has any issue ever been reported by customers globally.

If you have outstanding concerns on this question, please contact your race organizers and ask if their timing chips are affected by magnets.

Do Sharkbanz have batteries?
No - Sharkbanz do not use batteries and thus do not require charging. They are powered by the magnetic field of the earth and are always "on". As long as the magnetic technology is not exposed to heat over 150°F (65°C) and the chassis is not physically damaged, the Sharkbanz are operational.

How long will my Sharkbanz Last?
As long as your Sharkbanz are not exposed to heat over 150°F (65°C) and the chassis is not physically damaged, then the magnetic technology will not lose its power. The longevity of the band varies depending on frequency of use and amount of abuse. If there is a problem with your Sharkbanz, please let us know.
