Stealth suit for divers

A wetsuit that masks electric energy is allowing divers to get closer to marine life.

The HECS Stealth suit was developed for spear fishing but is now being used by film-makers, photographers and marine scientists.

Earlier this year it won the most innovative product award at the DEEPEX free diving show in Athens, Greece.

Warren Bird of HECS Aquatics - the New Zealand-based firm which developed the suit - said: ‘All living creatures give off energy and the energy signal is either used by predators to hunt out their prey or it acts as a warning signal to other species that danger is approaching.

‘Species like crayfish, rays, sharks are very sensitive to receiving energy signals. When wearing the HECS technology the signal that the human body is emitting does not pass through the carbon grid.
‘In situations where a diver wants to get closer to marine life that is relying on receiving the energy signal that particular species will not be able to pick up the signal. Thereby allowing the diver to get closer.
‘HECS does not make the wearer totally undetectable to all marine life as other senses like smell, sight and sound are still in play.
‘Our HECS technology is designed to allow all wearers (above or below water) to get closer to animals and marine life in their natural undisturbed state.
“This makes for a more relaxed experience both for the HECS wearer and the animal and marine life that is being studied.”

The suit is in effect a Faraday cage which inhibits electrical signals being emitted by a diver.
Testimonials provided by the company support the claims that it allows you to get closer to marine life. Marine biologist Riley Elliott said: ‘The HECS technology blew my mind. In fifteen years underwater I have never had such interaction with a crayfish – I was literally stroking its face. It was incredible.’

Underwater photographer Jason Scanlon said: ‘HECS is awesome. During a recent trip to the Bahamas I had the opportunity to wear the HECS dive skin. It was extremely comfortable and fit very well. During the first set of dives I started to notice that most of the wildlife ignored me and would swim around and near me as if I wasn’t even there. I was able to get very close to the life, which allowed me to capture photos and video that others on the dive could not. As the week progressed I noticed that most of the life would treat me as if I were one of them instead of an intruder into their space, some even ran into me.’
