Two weeks ago the company Shark Shield made the public announcement of their new electronic shark deterrent systems product line. These devices are the next generation in shark attack prevention systems based on the not so old PODs (Protective Oceanic Device) designed to be used by scuba divers, snorkelers and surfers.
The unit, according to the manufacturer creates an elliptical field that surrounds the user with an electric shield up to eight meters in diameter. I think this is a neat mechanism to prevent shark attacks. The Shark Shield will only deter sharks, rays and skates; it will not affect any other animals so, you can enjoy underwater photography or underwater video without disturbing the star of your movie or picture. By the way, it will not scare any seahorses or jellyfishes! :-)
The Shark Shield uses three-dimensional electronic waves that create muscular spasms and discomfort in the Ampullae of Lorenzini, one of the main the sensing organs of the sharks. These sensors are capable of detecting with accuracy electric fields, voltage and temperature in the water. What an incredible technology, no? I am referring to the shark’s sensors!
For almost US$600, this device can save you from one the worst underwater nightmares: a shark attack. An increasing number of companies and divers are buying this protective system for work or recreational purposes. Prevention and safety are good things, but also is good to know that a representative of the manufacturer said that the device worked 90% of the time repelling sharks, but it is not very effective when sharks are in an extremely agitated state.
In any case, there is always risk involved when diving with sharks.
