Cutting-edge Kiwi-designed wetsuit allows divers to swim near dangerous marine life

A New Zealand company is giving divers the ability to remain largely undetected by marine life by masking their energy signal.

The Hecs Aquatic Stealthscreen suits use technology they call the Human Energy Concealment System.

They say it's a bit like a whole-body Faraday cage which masks the natural energy given off by humans.

Tests show that wildlife encountering divers wearing the suits are much more relaxed.

A video created by the company shows a crayfish actually advancing towards a diver's hand, compared to the way they usually retreat at the faintest touch.
