- A $500 rechargeable device that clips to a surfboard reduces the chance of a shark attack by 66%
- The Rpela V2 was tested on great whites in Western Australia’s Salisbury Island, which is considered a ‘hotspot’ for sharks.
- It clips into the lower deck of the surfboard and uses an electric field to overwhelm the sharks’ electro-reception organs which they use to navigate
- The Rpela V2 cuts shark interactions (like nudges) with surfers by 38%
Had the people of Amity Island had it, it would have turned out very differently than Jaws.
Researchers from engineering company Cardano and Bond University have found that a $500 rechargeable device that clips onto a surfboard reduces the chances of a shark attack by two-thirds.
Experts tested the device, known as Rpela V2, on big whites in Salisbury Island, Western Australia, long considered a ‘hotspot’ for sharks.

Researchers find that electric pulses do not endanger sharks
The device clips into the surfboard’s lower deck and uses an electric field to overwhelm the sharks’ electro-reception organs that they use to navigate.
The researchers found that the electric pulse did not pose any threat to the sharks.
“Such stimulation does not harm the shark, but may encourage the shark to move rapidly away from an area or to change its behavior,” he wrote in the study, comparing it to a person who ‘Gets away from too loud music that becomes obnoxious. ‘
The researchers also found that Rpela V2 reduced shark interactions (such as nudges) with surfers by 38 percent, giving them extra time to get out of the water after encountering an apex predator.
“There are many different shark deterrents available, but most, including some very popular, are not effective or have not been independently tested,” said study co-author and Bond University shark expert Dr. Daryl McPhee. Statement.
‘This means surfers can put themselves at risk thinking they have an extra layer of protection when they don’t.’

Dr. McPhee said that although no shark deterrent is 100 percent safe, it is important that surfers (who are at highest risk of shark attacks) understand that electric deterrents are considered the most effective.
“As well as the Rpela V2 we assessed in this study, the electric deterrents developed by Ocean Guardian have been tested multiple times and shown to be effective,” he said.
‘No shark deterrent is 100 percent effective, but when independent testing shows a statistically significant reduction in interactions with sharks, consumers can be confident that protection is enhanced.’
The findings were published in Journal of Marine Science and Technology.
According to the study, there has been an increase in the level of shark attacks on the continent with 18 unprovoked attacks occurring in Australia in 2020. International Shark Attack File (ISAF)Despite the COVID-19 pandemic.
There were 57 unprovoked cases of shark attacks on humans in 2020, down from the 2015-2019 average of 80 per year.
Despite the low figure, due to the COVID-19 pandemic, shark attacks killed 10 people in 2020, the highest figure since 2013, in what some experts described as an ‘unusually fatal year’.
However, ISAF noted that ‘short-term trends still show both fatal and non-fatal bites to be low’ and that the higher number of incidents in Australia ‘is not a cause for alarm.’
Unprovoked shark-related deaths average four per year.
Of the 548 known species of sharks, just over two percent are known to attack humans, but three — the bull shark, the great white and the tiger shark — account for the majority of them.
In July, a study found that Hollywood shark movies portray sharks negatively, harming conservation efforts.
How the Sharks earned their ruthless reputation
Sharks are the most efficient predators on Earth and have long scared humans.
Their original design has never really changed over the course of 200 million years and they are considered complex and intelligent.
Their teeth are fear factor number one, with great white teeth growing to two and a half inches in length.
Their prey is pinned on the fangs of the lower jaw where they saw parts of the flesh. The serrated edges of the teeth help in this process.
Their teeth are brittle and constantly breaking but also growing continuously and on average there are 15 rows of teeth in the mouth at a time.

Their speed is fear factor number two.
They are much faster in the water than humans, with the mako shark capable of reaching an incredible 60mph.
The great white can reach speeds of 25mph.
By comparison, 5mph is the fastest a human can reach.
The strength and size of sharks terrify us too.
The great white shark can grow up to 20 feet and while it has no special taste for humans, even an exploratory bite can cut a man in half.
Most sharks release humans after their first bite, but sometimes, that’s all it takes to kill a person.
However, sharks have even more reasons…
