In recent times, there have been shark attacks off the coast of Long Island in New York, sparking concerns among ocean enthusiasts about how to avoid potential encounters with these predators. One solution that has been proposed is the use of shark repellents.
Shark repellents come in various forms, such as bracelets, anklets, and surfboard wax. Some work by emitting electrical pulses underwater to disrupt a shark’s ability to detect prey, while others release odors that sharks find unappetizing.
However, it’s important to note that shark repellents are not foolproof, according to shark behavior experts. Different shark species, including tiger sharks, bull sharks, great white sharks, and hammerheads, have different behaviors and react differently to the various types of repellents.
It’s worth mentioning that the chances of being bitten by a shark are incredibly low, with odds of 1 in 3.7 million. In fact, more people drown in the ocean each year than suffer shark bites. The likelihood of a shark attack is also lower than winning the lottery, dying in a car crash, or getting struck by lightning, as stated by Gavin Naylor, director of shark research at the Florida Museum of Natural History.
The Save Our Seas Foundation emphasizes the importance of rigorous peer-reviewed scientific testing to determine the effectiveness of a shark repellent. Their own tests revealed that most products on the market had limited or no discernible effect on shark behavior.
With that in mind, let’s explore five popular shark repellents:
Freedom+ Surf by Ocean Guardian
Ocean Guardian, an Australian company, offers the Freedom+ Surf, a 6-foot surfboard with a power module that emits an electrical current around the board and surfer. The module lasts for several hours and can be recharged.
A study conducted by the Save Our Seas Foundation found that the Freedom+ Surf was the only repellent among the tested products to have a measurable effect on shark behavior, specifically great whites.
Rpela
Rpela is a device that emits underwater electrical pulses to deter sharks. The Australian company collaborates with independent installers worldwide to attach the device to surfboards.
According to Naylor, using an electrical field as a deterrent works best when sharks are curious rather than actively hunting for food.
SharkBanz bracelet
SharkBanz utilizes magnets to disrupt sharks’ sensitivity to electromagnetic fields. The bracelet can be worn on the ankle or wrist and does not require charging.
Modom Shark Leash by SharkBanz
The Modom Shark Leash is a thin cord that can be attached to an individual’s ankle while swimming. Similar to the bracelet, it emits an electromagnetic field that is claimed to keep sharks up to six feet away.
Chillax Surf Wax by Common Sense Surf Company
Chillax surf wax relies on odors to discourage sharks from approaching humans. The combination of eucalyptus, chili, cloves, cayenne pepper, neem, tea tree oil, citronella, and beeswax creates an odor that sharks dislike. This wax is currently produced by a one-man operation in Queensland, Australia.
