Who are Sharkbanz for?

Sharkbanz are for the casual beachgoer, swimmer, and surfer. This 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.

Who are Sharkbanz not for?

There are a few more dangerous professions and situations in the ocean where protection beyond the level of Sharkbanz is recommended. Commercial divers, spear fishermen, and anyone swimming, diving or surfing in waters known to be hot spots for Great White Sharks are advised not to rely solely on Sharkbanz as protection. Sharkbanz are designed to prevent investigative bites from curious sharks in shallow coastal waters, not to stop sharks from eating bait or stealing your catch. 

Great White Sharks are ambush predators and operate in a fundamentally different way from all other species. While Sharkbanz might help your cause, we certainly wouldn’t go swimming near a seal rookery and expect not to be bitten.

How many do I need? 

One Sharkbanz will give you protection for your ankle or wrist, although two will provide greater defense. For swimming or surfing, we suggest wearing them on your ankle. When scuba diving or snorkeling, the wrist is preferred so that the band can be more easily directed at a curious or aggressive shark, but please be mindful of our magnetic technology and how it may interfere with a diving computer. When surfing in sharky waters, our Founder wears one on each ankle. If you're absolutely terrified of sharks, you could fit quite a few on each limb!

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 I need to be moving to generate the magnetic field?

The magnetic field is generated by your movement, but you don’t need to be overactive. 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 and other scuba electronic systems? 

Sharkbanz technology can harm electronic devices, including electronic scuba equipment, and should be kept at least 12 inches (30cm) away from these devices. If you are handling electronic equipment while diving, we suggest placing Sharkbanz on your ankles to avoid direct contact with the electronics.

Will Sharkbanz attract sharks?

No! Sharkbanz emit a magnetic field that drops off quickly, so sharks cannot sense it from far away. Once they enter the magnetic field, they are quickly deterred.

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, follow this link to our partners at SharkDefense.

*Note from the scientists: 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 much less than most predatory species, instead relying on their keen senses of site, 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 electromagnetic sense when swimming in open water, and Sharkbanz could effectively deter an investigating Great White.

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.

What is the depth rating of Sharkbanz?

Sharkbanz do not have any electrical or pressurized components, so they are safe from damage up to 200M.

Do Sharkbanz affect any other animals in the ocean?

Sharkbanz technology also deters stingrays, an added benefit to the product. The technology is not known to harm any other ocean creatures such as dolphins, sea turtles, or fish.  

Do Sharkbanz have batteries?

Sharkbanz have no batteries and thus require no 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 140°F (60°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 140°F (60°C) and the chassis is not physically damaged, then the magnetic technology will not lose its power.  With regular use, we expect your Sharkbanz band to last approximately 3 years. If there is a problem with your Sharkbanz, please let us know.

I purchased Sharkbanz and don't have any instructions on sizing, care, etc... where do I find this information?

No worries friend! Instructions are always available at sharkbanz.com/protected.

After wearing my Sharkbanz, it appears as if something is leaking out of the banz…is my Sharkbanz defective?

No! The magnets are very powerful and all ferritic (iron) particles will stick to the banz and sometimes look like a dark goo. Don’t worry; your Sharkbanz is not leaking, nor is the effectiveness reduced. The best way to clean the particles off is to use a slightly damp or dry towel and smoothly wipe them away.

Will Sharkbanz fit me? What about my child?

Sharkbanz are designed to fit on either your wrist or ankle. Sizing the band to your ankle using the instructions at sharkbanz.com/protected will allow you to wear in both places. In rare cases, Sharkbanz may not fit. The best way to find out for sure is to measure the circumference of the wrist or ankle with a tape measure. If it’s between 5.5 and 14 inches (14 and 35.5 cm) then you're are all set!
