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.
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.
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.
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.
If you have metal or medical devices under the skin, always consult with your doctor before purchasing and using Sharkbanz.
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.
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.
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.
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, and here.
Great Whites rely heavily on their electroreception when swimming in open water, and Sharkbanz could effectively deter an investigating Great White.
However, it's important to note that 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.
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.
Sharkbanz and Sharkbanz 2 do not have any electrical or pressurized components, and Sharkbanz 2 are waterproof tested up to 100M.
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 140°F (60°C) and the chassis is not physically damaged, the Sharkbanz are operational.
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 effectiveness. 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.

No worries! Instructions are always available on our Product Care page.
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.
Sharkbanz are designed to fit on either your wrist or ankle. Sizing the band to your ankle using the instructions found on our Product Care page 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 all set!
