Shark Shield this week announced the opening of its first U.S. office in St. Petersburg, Florida.

According to the company announcement:

After 12 years of leadership in the Australian spearfishing and dive market, we are now opening our U.S. office to support local U.S. spearfishers and divers and to educate other water sports enthusiasts on alternatives to shark culling and powerheads. Shark Shieldhas been protecting people and providing peace of mind for nearly 20 years, supplied over 20,000 units and have hundreds of user testimonials.

Shark Shield’s technology is based on more than 20 years of scientific research by some of the world’s leading shark experts and is used by the Australian Navy, U.S. Navy & Coast Guard and professional abalone divers and spear fishers around the world. The company recently signed Tom Carroll, two-time World Surfing Champion, as its brand Ambassador in the surfing and stand-up paddle board markets.

The three Shark Shield devices, SURF7, SCUBA7 and FREEDOM7 create an electronic shark barrier by using salt water as the conductor to produce an electromagnetic field that disturbs the sharks’ (ampullary) receptors used to find food. There are no known long-term effects to the shark from the electrical field, but the discomfort is enough to discourage interaction with humans. The field is not detectable by other ocean creatures like the catch you are hunting. As a result, many professional divers and spearfishermen use Shark Shield as their most important piece of equipment.

Shark Shield is currently being sold in dive shops and spearfishing stores. Retail prices range between $599 and $699.

Anyone wanting Shark Shield to visit their dive or spear club to present the company’s technology, as well as the independent testing results including video, should contact Scott Wilson, U.S. sales manager, via email at scott.wilson@SharkShield.com or by phone at +1.727.301.8835.
Sunday 7th February saw over 3,500 swimmers take to the water in The Sydney Morning Herald Cole Classic presented by Virgin Active. Little did they know that Shark Shield, the world’s only scientifically proven and independently tested electrical shark deterrent devices were protecting them throughout the race.

Twelve Shark Shield’s were attached one metre below on the large swim buoys that marked out the course, creating a loose electrical shield and providing a place of refuge in the unlikely event that a shark sighting occurred.

Lindsay Lyon, Shark Shield’s Managing Director said, “We were approached by the event organisers who were pro-actively seeking out proven technology to reduce risk for their contestants.”

“Traditionally, our products haven’t been used in organised ocean swims. However, in theory the devices would provide a loose electrical shield to turn sharks away had they ventured into the area, and most certainly a place of refuge for swimmers if required,” Lyon said.

Choice, Australia’s leading independent consumer watchdog, recently announced Shark Shield as the only effective shark deterrent on the market. Following an extensive review of the shark deterrent options currently available, Shark Shield was the only deterrent shown to be independently tested and scientifically proven to turn sharks away.

“The use of Shark Shield’s at this event is a good example of how our proven deterrent technology can be used as a preventative measure to reduce risk to the community. We remain open the opportunity to work with other water sport events and competitions,” added Lyon.

Following their presentation at the Senate inquiry into shark mitigation and deterrent measures
last week, Shark Shield, manufacturers of the world’s only scientifically proven and independently tested electrical shark deterrent, has today announced the pre-production release of a long-range version of its technology. The new Shark Shield Ocean Guardian is based on 20 years of research and utilizes a patented Metamaterial Electromagnetic Transducer, with expectations of repelling sharks within a 100-meter diameter of each unit installed.

Lindsay Lyon, Shark Shield CEO says, “The Ocean Guardian has been many years in the making and has come about through a partnership with leading physicists and biologists. We have been able to produce a long-range shark deterrent solution to not only protect beach goers but significantly reduce the environmental impacts caused by using shark nets, drum lines and culling.”

The new transducer form is based on technology used to treat patients in the medical field including, oncology, urology and other chronic diseases, with clinical studies demonstrating that the electromagnetic field does not affect the health of humans or ocean life, such as sharks or dolphins.

“Sharks have small short range electrical receptors in their snouts used for finding food. Shark Shield’s electromagnetic field causes unbearable spasms in these sensitive sensors, which turn sharks away, this has been well proven over the past twenty years. The Ocean Guardian leverages this weakness in sharks to not only deter them, but in the long run we hope to teach them to stay away from beaches protected by Shark Shield,” says Lyon.

“Classical conditioning, also known as Pavlovianor respondent conditioning, refers to a learning procedure in which a biologically potent stimulus, such as food, is paired with a previously neutral stimulus, such as long term use of Shark Shield Ocean Guardian. With our Ocean Guardian in place, over time sharks will learn...

The cold of winter is really starting to settle in, but instead of rugging up and hibernating like the rest of us, Kohen Grogan plans to ride a floating bike from Cottesloe Beach to Rottnest Island. With the help of Ocean Guardian, powered by Shark Shield Technology, Grogan will be taking on the icy 23km ride in waters well known for shark attacks. Grogan plans to tackle his ride between 1 – 14 June.

Although he’s previously described himself as “incredibly unfit”, Grogan aims to train hard in an effort to raise $10,000 to help build a school in remote Cambodia.

“Currently, most children have to travel 2.5 hours each way to get to school. There are also approximately 121 million primary and secondary age children that don’t have any access to education. To help this crisis we will also be building clean water drinking facilities, toilets and a solar station”, says Grogan.

To aid Grogan in his risky but courageous ride, Ocean Guardian will be loaning him a FREEDOM+ Surf to attach to his catamaran-bike hybrid. Ocean Guardian’s Shark Shield Technology has been protecting ocean adventurers for 20 years and has again recently been scientifically proven to significantly reduce risk and deter white sharks, with new research led by Flinders University and commissioned by the NSW Department of Primary Industries.

Lindsay Lyon, CEO of Ocean Guardian says, “We are honoured to be helping Kohen complete his ride by offering him a little extra protection to ensure he accomplishes the journey safely. We wish him all the best and sincerely hope he reaches his goal.”

Introducing Ocean Guardian’s FISH01 – Powered by Shark Shield Technology

Raising high quality fish species from the depths can be a demoralizing experience if sharks are in attendance. Thanks to the latest innovation from Ocean Guardian, the new FISH01 has been specifically developed for the fishing industry to improve catch rates by reducing shark tax.

The new device is powered by Shark Shield Technology, the world’s only scientifically proven and independently tested electrical shark deterrent, and has been proven to prevent the majority of shark species from attacking hooked fish, improving efficiency and resulting in less time at sea.

Ocean Guardian CEO, Lindsay Lyon, says, “The major outcome from a trial using Shark Shield Technology conducted by the Western Australian Fishing Industry Council indicated that electrical shark deterrents do deter the majority of shark’s species from attacking hooked fish.”

“For many years we have known that both recreational and commercial fishermen have been using our Shark Shield Technology to significantly improve catch rates, we are now very excited to deliver a product specifically designed to meet their needs, the FISH01”

Key features of the FISH01:

Dramatically reduces collateral damage from sharks
Between 10-12 hours of battery life – continuous operation
Protective field up to 15 meters deep and 6 meters wide
Maximum operating depth of 200m
