Shark repellent bands offer false safety, experts warn after fatal attack

Experts say popular magnetic shark repellent bands give swimmers a false sense of security and have not prevented attacks.

A shark expert warned that wearable bands don't work well. A 65-year-old woman was killed in a shark attack off South Africa while wearing a magnetic band.

Shark expert Sharky Baxter called the devices little more than a sugar pill. The bands give people false security, he said.

Scientist Maddy Massie explained that magnetic deterrents only work within about 1 metre. Electric devices are more reliable, they interfere with a shark's electrical senses.

But neither type guarantees safety. Experts also noted that sales surge after shark attacks as worried swimmers rush to buy them.

Why it mattersThe bands don't work reliably. Experts say swimmers should focus on proven safety: swim between flags and stay in groups.

AustraliaAustralian swimmers also use magnetic shark repellent bands under the assumption they work, though experts say the evidence is weak.
