This device could keep surfers safe from sharks

If you are afraid of sharks while surfing, you may want to look into this shark deterrent device.

The Rpela V2 was tested in shark-infested baited waters and reduced bites from white sharks by 66%.

The research was conducted in Australia through a collaborative effort led by global engineering company Cardno, Bond University shark expert Dr. Daryl McPhee and freediver Ocean Ramsey.

The device that weighs 5.5 ounces is mounted into a surfboard and produces an electric field around the boardrider that interferes with the shark’s electro-reception organs, which are used to navigate and assess their surroundings.

When the device was turned on, sharks kept a greater distance from the bait.

Non-bite shark interactions including nudges were reduced by 38%, potentially giving surfers extra time to exit the water after encountering a predator.

The Rpela V2 does not harm sharks but causes unpleasant sensations.

There are a number of electric deterrents commercially available to the public, all of which claim to be effective shark deterrents, yet most of them have not undergone robust and independent scientific scrutiny.

McPhee, who has no financial connection to the researched product, said that overall, electric deterrents are the most effective compared to magnetic, acoustic and spray devices.

It should be noted that the chance of unprovoked shark bites in areas where dangerous shark species occur cannot be reduced to zero.

“No shark deterrent is 100% effective, but when independent testing demonstrates a statistically significant reduction in interactions with sharks, consumers can be confident that safety is enhanced,” McPhee said.

The study only involved seven white sharks off the southwest coast of Australia, and it is uncertain if these results would be as effective for other species or locations.

The devices are about $500 and must be professionally installed in a manner similar to routing in fin boxes. Once installed, the part of the unit can be removed for cleaning and charging since the power won’t last all day.
